Well, some of the "avert your eyes" applied to the USPS bike is due to the 
largely erased history it was involved with, but yeah, it's not much to look 
at.

FYI, that DiNucci was built for Patrick Brady over at Redkiteprayer. He 
wrote a few articles on it. This one 
(http://redkiteprayer.com/2017/02/the-dinucci/) describes the tubeset and 
components.  Velo-Orange brakes, compact double, Zipp Wheels, fits 35 mm 
tires. Yellow Submarine–inspired paint job.

 You can help that luck by making sure your frame has a round seat tube

I have to agree. It is already happening with Shimano Dura Ace 1st 
generation di2. Parts are no longer available and the 800-1000 users are 
out of luck or have to pay exorbitant prices for spares!  I know one guy 
who got rid of his 1st gen DA carbon bike and now has a new carbon bike 
with guess...mechanical Sram Red!  :)

Btw, my calfee is now 20 years old since I bought it used in 1997 (I 
believe its a 94 model) and is still going strong. I have easily over 
30,000 miles on it and expect it to last another 20 years. But the latest 
carbon frames out of Taiwan are much much lighter and who knows how long 
they will last.then again, the MUSA Trek Emonda SLR frame that weighs 
680g has a weight limit of 275lb, so who knows?! Good Luck!

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

I think you've nailed it with "respect for 50yo carbon frames", they will be 
virtually non-existent. There's no real concern for the longevity of current 
electronic shifting systems because they'll be replaced in a few years along 
with the frame they're attached to. 

I think traditional steel bikes with manual components will continue to be 
passed around and restored indefinitely, but this is simply not the case with 
carbon racey bikes. We are in the era of the disposable bicycle in that market.

I disagree. I think e-bikes are here to stay.


I think you're talking at cross purposes.  Electronic shifting may 
persist -- although it no longer seems to have the "must have" cachet it 
did when it was the flavor of the month, as far as I can tell -- but 
what is the chance that 50 years from now you'll see "classic" carbon 
bikes with people fetishizing the original 2017 DI2 shifters and 
derailleurs?  Because that's what Garth is talking about, not whether 50 
years from now there will be e-bikes at all. With no batteries, those 
systems won't run, unlike dumb mechanical systems.   Electrically 
motorized bicycles - who knows?  Long term viability probably depends on 
factors unknown right now.  How many gas powered mopeds do you see?  
None at all where I am.




Besides the "racing" stuff like di2 and etap (which btw uses standard 
2032 batteries for the shifters, but requires proprietary batteries 
for the FD and RD), there are numerous e-bikes out there for many 
uses. On my commute home, I have several hills to climb. I routinely 
get passed going up by a Bakfiet and Yugo cargo bikes loading with 
kids and groceries. I also get passed by kids on e-skateboards going 
up hill!  The latter is kind of a trip as you see these kids standing 
on their e-boards cruising up the hill.


Also, e-bikes are a good way to get just one more car off the road. I 
usually talk to the owner and most appear to be moms. I find it 
interesting and a lot more fun than driving a minivan, which I had 
when my girls were small.


Yes, batteries are going to need replacing at some point. But like a 
car, they should be available.  After all, if there's money to be 
made, I'm sure the mfrs will continue to provide it! Good Luck!


I'm not sure cars are a good analogy.  There's a lot of room in an 
engine compartment for a battery, and if the OEM is no longer available 
it's possible to fashion something to accept a battery that is 
available.  The e-shifter batteries really are pretty proprietary and 
there's not a lot of room to play with alternate form factors.  I'd 
guess camera batteries are a better analogy -- except that I suspect, 
based on current attitudes towards older carbon frames, that top line 50 
year old cameras get a lot more respect and collector interest than any 
50 year old carbon frame will.


But I'm just guessing.

That's great! If a 1984 Trek is all you need to ride, then I say Just 
Do It!  In contrast, I have a buddy who just got into riding about 5 years 
ago. He has the latest Trek (well, 2014 version) with di2 and all the 
works. It got him riding and he has now lost over 30lbs and flies up 
the hills!  I had been trying to get him on a bike for 20 years, but you 
know what was stopping him? dt shifters. He couldn't stand having to reach 
down to shift. Same goes for bar-ends. However, with integrated shifters, 
where your hands almost never leave the bar, he's into it!  He is now one 
of the guys pushing everyone to get out of bed on the weekends to ride! He 
also rides on the weekdays after work during the summer. 

So, what ever floats your boat and gets you out on the bike, I say go for 
it and enjoy! Good Luck!

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Nick Payne]

No, they're just chainrings I had in my parts collection. Probably
originally 8- or 9-speed - definitely not 10-speed. The 36t is a Shimano
and the 24t a stainless steel Sugino. Take no notice of the garbage
spouted by the manufacturers about needing speed-specific chainrings.
I've got several bikes running 11-speed chains/cassettes and not a
single one of them has "11-speed chainrings".

I've used generic Sugino and ancient Pro 5 Vis rings with 10 speed chains;
no problems at all.

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

Are those standard Sugino rings, and they work fine with a 10 speed chain?
One of the chief issues I'm running into is finding 10-speed specific rings
in my preferred tooth count/BCD...

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Jim Bronson]

Yes, I don't just want, I *NEED* high-q.  Low-q makes my knees hurt, all
other things being equal.  I've tried, believe me.  I'm just big with big
hips and my feet need to be farther apart than that.  I use pedal extenders
on top of having a high-q crank.

 I have had no problems mixing SRAM road and mountain 10 speed
 derailleurs and shifters with 44/28 and 42/26 cranks and 11/32 or 12/28
 cassettes.  Even on my Calfee, now sadly sold.

 You can help that luck by making sure your frame has a round seat tube
 and uses a clamp on front derailleur.  Which pretty much means a titanium

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Bill M.]

I have two Campy Record Triple cranks that I run without outer rings to 
create ultra-compact doubles.  135 mm TA and Stronglight chainrings are 
available from XX Cycle in France.  Bottom brackets are pretty scarce, 
though.  The inner is a standard 74 mm ring.

Many iBOB's will shudder at the thought of a slightly wider q factor than 
they would like.  In my case, my toes point out quite a bit, and the Campy 
arms offer good ankle bone clearance so they fit me well.

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Patrick Moore]

A thought as an aside: a 44 X 12 (99 gi with 27" wheel) is smack in the
middle of a 50 X 13 and a 50 X 14; and at the other end, a 24 X 32 (20 gi)
is just 10% lower than a 30 X 36 (22 gi).

I got compact, indeed sub compact, gearing with a 52/38 using a cassette
with a 16 t Miche outer cog. IOW, there are ways to accommodate high tabs.

 You can help that luck by making sure your frame has a round seat tube

 I bet most FD hanger tabs will allow a crank to go from 53/39 to something 
with a 48/34 or maybe and this is a stretch 46/34 combo.

For the most part, electric shifting is pretty rock steady.   Being 
with a shop that sells them, I've had one DI2 come back.   One.   I 
stopped trying to see how long the battery lasts, It just keeps going 
and going.


If you mean how long a /charge/ lasts, I had a woman on a ride I led 
last month whose DI2 unit went into the first warning mode of low 
charge, shifting to the small chain ring and refusing to budge from it.  
This happened something like 15 miles into the ride, and she spent the 
rest of the ride rationing shifts hoping to finish the ride before the 
unit quit working entirely.  It had been "a very long time," she said, 
since she'd even checked the state of charge, never mind charged the 
system, and had no clue how many miles she'd gone.   It may be rare, and 
it may take a long time to get to that state, but it definitely does happen.



I've stopped counting defective cable actuated parts.   No need to 
count really, we have an open RA number for Sram.Best warranty 
program in the business.  Though  if they didn't build crap they 
wouldn't need it.


Some people can break anything.   They shouldn't have nice things.


Moreish on the topic.   Clamp on front derailleurs are the way to go. 
My 46x28 likes them.


Yes, they're great - but they do require a round seat tube and OMG how 
boring is that, right?

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Jim Bronson]

Yes, I carry spare cables at all times, and on really long brevets (more
than 600K) I carry an extra bar end shifter too!  And a spare tire too for
that matter, at all times.

I run high spoke counts so I don't have to carry spare spokes - never had a
spoke fail on a wheel with 36 or more spokes that was built by a competent
wheel builder.  If I ran wheels with lower spoke counts I would carry a
fiber fix spoke.  (have some 32H Pacenti SL23s hanging in my garage I am
considering having built up...)

You can help that luck by making sure your frame has a
round seat tube and uses a clamp on front derailleur. 
Which pretty much means a titanium frame.



Or a Calfee.  Which, come to think of it, Brewster already owns.


Haha, my secret is out!  Actually, I'm thinking of getting one of
these really lightweight carbon bikes to see what all the fuss is
about. I see my buddies with these 14-15lb bikes with e-shifting
and they're loving it!  I mean, take a look at the latest Trek
Emonda. With not really stupid light parts, you can get a 10.25lb
bike that supposedly has a weight limit of 275lb?!  Yow!  I doubt
there are many here who are that heavy, but if so, there it is!


The Calfee may have a round seat tube, but I'm pretty sure none of
the Trek "Anagram" bikes do.





I do agree that a round seat tube with a clamp on FD is ideal.
However, my 90-ish Litespeed Classic ti bike has a braze-on FD
hanger tab and I have my FD mounted at the lowest point for my
48/34 crankset.


And some braze on mounting tabs have their slots configured to
allow smaller than 50T big rings.  Many these days do not.  It is
a limiting factor you need to be aware of.


Agree. At last year's NAHBS, I got into it with Mark DiNucci, one of 
the premier builders at the show!  When I heard he was showing, I 
really wanted to check out his frames. He didn't disappoint as he had 
2 or 3 of the cleanest bikes/frames on display:










Beautiful work especially the long thin lugs that just flow into the 
frame. Gorgeous! But one question I had for him was whether I could 
get a frameset without the FD hanger tab. He blew up! He asked why? I 
told him I wanted to be able to adjust the FD to work with whatever 
crank I got. He then went on about how they design the frame with the 
crank in mind and how the hanger tab would be properly place!  Since 
he got animated, I let it go. But later thought, I should have asked 
what happens if someone decides to change their crank?  Let's say you 
are young "racer" type and want to use a crank with 53/39 chainrings. 
Later, you get older and slower and want more gearing so you go to 
50/34 or 48/34.  Will that new crank if the FD hanger tab? Let's say 
it does. Then a few years later, you want to go even smaller like a 
44/30 or 44/28?! Will that tab still allow the FD to work with this 
new smaller gearing?!


I guess if I ever get the money for a DiNucci, that is one of the 
questions I'll be asking! Good Luck!




Going from the now omnipresent 35/50 to 39/53 is within the capabilities 
of the common hanger tab you find on many (most?) carbon road bikes 
these days.  The problem is going smaller than 50.  There may well be 
some, my experience with modern carbon road bikes is very limited, but 
the ones I've looked at have not.


As for future compatibility with other cranks and chain ring 
combinations, I'm guessing that's not an important consideration for 
bike designers these days.  Getting older & slower?  You'll probably 
need to raise your bars a bit too, and good luck with that if they cut 
your steerer so as to not leave any extra for future needs.   You need 
those changes?  Get a new bike.

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Scott Henry]

Not sure on why you would need a tablet.   Do you take extra cables and
spokes on your rides too?

For the most part, electric shifting is pretty rock steady.   Being with a
shop that sells them, I've had one DI2 come back.   One.   I stopped trying
to see how long the battery lasts, It just keeps going and going.
I've stopped counting defective cable actuated parts.   No need to count
really, we have an open RA number for Sram.Best warranty  program in
the business.  Though  if they didn't build crap they wouldn't need it.

Some people can break anything.   They shouldn't have nice things.


Moreish on the topic.   Clamp on front derailleurs are the way to go.My
46x28 likes them.

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Jim Bronson]

The one Randonneur that I know who has electronic shifting, it has failed
him twice on long brevets.  He says hooking it up to his laptop and
resetting the whole system fixes it.  He's an extremely strong rider
despite being in his mid-60s and he can deal with having front shifting
only.

Last time this topic came up I researched some Windows 10 tablets on Amazon
and there were some that weighed less than a pound that cost around $100.
That would be the price for me to get electronic shifting, I would have to
have something with me on the bike that could run Shimano's software for
troubleshooting..  I would need to have the tools to service it in the
field.  I am not strong enough to just jam it up steep hills with whatever
gearing that I had available with the rear derailer fixed in place.

buddies with these 14-15lb bikes with e-shifting and they're loving it!  I 
mean, take a look at the latest Trek Emonda. With not really stupid light 
parts, you can get a 10.25lb bike that supposedly has a weight limit of 
275lb?!  Yow!  I doubt there are many here who are that heavy, but if so, 
there it is! 

I do agree that a round seat tube with a clamp on FD is ideal. However, my 
90-ish Litespeed Classic ti bike has a braze-on FD hanger tab and I have my 
FD mounted at the lowest point for my 48/34 crankset.  

Alternatively, if I don't go crazy and get that fancy carbon bike, I'm 
still thinking about a custom steel. If so, it will definitely use a 
clamp-on FD adapter. Or, if I must put on a FD hanger tab, it is going to 
be either one really long hanger or mounted very low so I have the option 
of running anything from 53/39 to 46/28 or smallerGood Luck!

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[ascpgh]

I attached that video of Merckx to give image to Jan Heine's observation of 
the riding style necessitated by the CFRP frame he tested in the current BQ 
and how it differed from his regular bike(s) with frame flex, suppleness. 
He illustrated his point by describing how Merckx pedaled with his whole 
body, as you described, standing in the hooks without downshifting to 
torque through the obstacle.

Or a Calfee.  Which, come to think of it, Brewster already owns.

I have had no problems mixing SRAM road and mountain 10 speed derailleurs 
and shifters with 44/28 and 42/26 cranks and 11/32 or 12/28 cassettes. 
 Even on my Calfee, now sadly sold.

On my wife's carbon BH Quartz, which uses a braze-on tab, an Ultegra 
Braze-on front derailleur was able to be positioned low enough to be in the 
correct position when using a crank with 44/30 chainrings: 




For 11-speed road shifters combined with wide range cassettes, use SRAM - 
their 10-speed MTB derailleurs use the same cable pull as their 11-speed 
road shifters. Here's the drivetrain on one of my bikes that uses Force 22 
road shifters, 42/29 chainrings, SRAM X9 MTB RD, and Shimano 11-40 11s 
cassette. SRAM publish a list of their "exact actuation" components at 
https://www.sram.com/sram/mountain/technologies/exact-actuation. All 
components on that list are compatible - just match the shifters to the 
number of cogs on the cassette.





I've never found any problem on two chainring setups with mixing different 
manufacturers front derailleurs and shifters. I have Campagnolo shifters 
with Shimano FD, Shimano shifters with Campagnolo FD, and SRAM shifters 
with Shimano FD.

Another combination that works perfectly is Campagnolo 11s shifters with 
Shimano 9s cassette and Shimano 9s RD, as the cable pull is virtually 
identical between Shimano 9s and Campag 11s. When my old pair of Ultegra 9s 
STI shifters started to fail several years ago, I found I could buy a pair 
of new Chorus 11s Ergo shifters as cheaply as the prices being asked for 
NOS Ultegra 6500 shifters, so I went that route.

[RBW] Current indexing systems and shifting in general, per the Knothole

[Joe Bernard]

The comment about people not buying cranks and shifters anymore struck me 
because I realized I'm kinda there now. I used to do a lot of drivetrain 
swapping/upgrading, more as part of the "hobby" than for any real hope of 
improving functionality. My Appaloosa came from RBW with Sugino cranks, Deore 
rear derailer and a rather clunky-looking Claris front. It's not a particularly 
cohesive look, not particularly light, and works fine..I feel no inclination to 
replace any of it with lighter/shinier stuff like in the old days. 

Then there's my ebike with a 1x10 Deore shifter and derailer: Click, click, 
click, ride, ride, ride..it's absolutely invisible to me out on the road, which 
seems weird. I'm becoming that person who just hops on and rides without giving 
much thought to what parts are making it go. I never thought this would happen.

Sure, if you could fit a 36/46 you'd be fine, but you were in this fix 
in the first place because of the slot in that mounting tab, so no joy 
to be found there.  Which means you're looking at MTB rear derailleurs 
and cable pull altering devices.





For my next bike, I'm planning on going etap "wireless" with mid-cage 
RD. I want to run 11-32 in the rear with a sub-compact double like a 
46x30 or 46x28.  Since I don't "tour" or carry a load, a 30x32 or 
28x32 should be more than enough to get me up the hills around here! 
Of course, YMMV! Good Luck!


You can help that luck by making sure your frame has a round seat tube 
and uses a clamp on front derailleur.  Which pretty much means a 
titanium frame.

Re: [RBW] Current indexing systems and shifting in general, per the Knothole

[Patrick Moore]

Segueing a lil' bit: there was another thread today on this list or
t'other, where someone attached old video of Eddy one one of the big rides.
Very interesting to see (I guess this was very early '70s) how pedaling had
changed from the days of Coppi and late Bartali. You watch even older video
of C and B on the flats, and they're spinning at very high cadences; Coppi
seemed to prefer the spin-coast, spin-coast, which I also favored 25 years
ago when I could maintain 20-23 in my favorite 64-65" gear. Then they hit
inclines, and they're grinding up in amazingly high gears at very low
cadences.

But Eddy and companions are pushing bigger gears on the flats, and it is
very interesting to see how, at the slightest rise or, perhaps, a turn into
a wind, they get out of the saddle, without downshifting, and torque their
way through the "obstacle." And they stand while in the hooks! (And, btw,
Eddy was a "messy" pedaler; you can't say he had finesse -- all over the
bike!)

I've not watched much Tour video since Big Mig, but I daresay that the
style now is fast spinning and maintaining cadence in all conditions and
terrains.

I guess the gaps are getting so narrow that any difference between marques
disappears. But that's a good thing.

What about derailleurs? Are road and mountain bike derailleurs compatible
with the opposite shifters? And what about shifter compatibility between
the different marques?

Frankly, if I were to use indexing, I'd at least seriously consider
wireless electric (I'm tempted to be snide and say, "If you've abdicated
shifting skill to indexing, you might as use electricity," but I won't).
But my last bike with indexing was the Ram, when I had it set up with 7
speed Dura Ace, and I didn't particularly like it. Friction for me.

Patrick "hell, fixed/single for me" Moore, who just had a nice 76" gear
ride on the gofast in breezy but sunny and warm ABQ, NM.

Seriously, if you don't shift so much, you have all the more attention to
give to other aspects of cycling, like cadence strategy -- but don't mind
me, I admit that it's *chacun/ne a son/sa gout/te.*

46x28.  Since I don't "tour" or carry a load, a 30x32 or 28x32 should be 
more than enough to get me up the hills around here! Of course, YMMV!  Good 
Luck!

With 9 speed and 10 speed Shimano road shifters use 9 speed Shimano MTB

5. 10 speed road chains are different from 10 speed mountain

The days of bike riders shopping for new cranks or cassettes or 
shifters is mostly gone. Or at least, it's not like it used to be, by 
a mile. Bike shops are so desperate (for the most part) that they want 
their suppliers to drive customers to their stores with new exciting 
things every year.


I was not aware, taking just Shimano, of the variety and complexity 
and incompatibility of the various indexing systems. Man, it all looks 
like a hassle I am very, very happy to avoid.


With Shimano road 11 they've taken road cassettes to 32T, but for many 
with the usual (and often not replaceable with any better gearing) 34/50 
that's not a low enough low gear.  It was much simpler in 10 speed days: 
replace cassette and rear derailleur as noted above and you're good up 
to 36T in back.  That won't work with 11, and it's necessary to enter 
the world of altering cable pull.

The days of bike riders shopping for new cranks or cassettes or shifters is
mostly gone. Or at least, it's not like it used to be, by a mile. Bike
shops are so desperate (for the most part) that they want their suppliers
to drive customers to their stores with new exciting things every year.

I was not aware, taking just Shimano, of the variety and complexity and
incompatibility of the various indexing systems. Man, it all looks like a
hassle I am very, very happy to avoid.

And the first sentence of the next paragraph seems very strange to me;
nothing is more natural than shopping for new cranks and cassettes and
shifters, in my world. I guess I live in an alternate universe, but one I
like much better. I've just replaced crankset and cassettes and shifters on
the Matthews.

Going from 9 to 10 *was* exciting, as far as these things go -- a very
modest excitement, of course. But it was at least very interesting to learn
that I can shift 10 cogs (and with misaligned ramps, at that, since the
cassette is made from a handful of cogs grabbed from my box, and includes
at least 8s and 9s and 10s, and probably 7s too) with Power Ratchets
pulling a 8 speed era rd. I'd be better off with a 9 or 10 speed
Microshift, with slower travel, but the 740n works fine even on dirt; I
just have to be careful. It *is* more finicky than 9, which wasn't much
different from 8.

The "new and exciting every year" is sad. But I know stores that are
modestly thriving by selling every day stuff in addition to exotic stuff,
and excelling with
