Re: [RBW] Re: Eroica California

2024-04-03 Thread Jim M.
I rode it on my Eisentraut with period appropriate Campy Nuovo Record and 
30mm tubular tires. As I recall, they allow newer lugged steel bikes, and I 
definitely saw a few Rivs. There were several folks from this list and 
I-BOB. There's a bike expo and Concours for people to show off their rides, 
which is great if you like looking at old steel bikes. There were awards 
for things like best original Cinelli. Central coast Calif has a lot of 
beautiful areas for riding. They partnered with local wineries to route 
through vineyard roads, so there was a lot of strade bianche. Riv content 
-- I met George Mount, who used to race against Grant back in the day, and 
I met Andy Hampsten, who has extolled Jack Brown tires.

Even OLD is TBD?  135?  130?  126?  120?  something else?  I'm super into 
120 and 126 lately, so I'll be interested to hear it if you are also

Re: [RBW] Gearing Choices

2024-04-03 Thread Nick Payne
I've attached a gearing spreadsheet I use, which allows me to easily 
compare three different gearing setups in the one sheet. It's in ODS 
(OpenOffice) format, but I believe that Excel can open and read that 
format. It also shows speed in each gear at a specified cadence - I have 
speed as KPH because we use metric in this country - if you want MPH 
values, just modify the speed formulas to divide the KPH values by 1.609.

I remember that, and probably could dig it up! And, yeah, you really have to 
build your own.

This is super important and where “YMWCV”! I should have prefaced my entire 
treatise by making it clear that most of my riding is in SE Wisconsin on mostly 
paved roads and crushed limestone trails. The limestone trails are abandoned 
railroad beds, so rarely exceed 2% grade. We have only a few hills that 
approach 20% and they are quite short. Mostly it’s rollers that are 5%, 
occasionally 10%. The wind, on the other hand ….  

Riding in the LA area, especially trying to go up avg 10% dirt/rocky trails 
that go on for miles, my gearing needs are somewhat different. One of the 
thoughts I’m keeping in mind as I spec a new bike is flexibility … if I travel 
with this bike, will I be able to easily modify the 
gearing/tires/fenders/racks/lighting to match the intended conditions. But 
then, I also have a few different bikes, so ultimate flexibility might not be 
paramount :-)

All TBD, but I can confirm that a Vx GT and a Cyclone MkII GT will cover 9 -11 
cog cassettes. In fact, a Cyclone MkII GT executes flawless index shifting on a 
9-speed 12-36 cassette using Shimano 10-speed bar end shifters. I’ve posted 
elsewhere about this … SunTour derailers should index perfectly on a 
Shimano-SRAM n speed cassette with Shimano n-1 speed shifters, where 7<=n<=9. 
By “index perfectly” I mean that the horizontal derailer movement is exactly 
the right amount given the cable pull. An odd and interesting historical math 
artifact.

What is also important is related to that. SunTour derailers have a high 
actuation ratio, meaning lots of horizontal movement relative to cable pull. As 
a result, “normal” shift levers are able to move a SunTour derailer across 8-12 
cogs where other derailers would require a shift lever with more cable pull (a 
larger diameter drum around which the cable is wound). SRAM and newer Shimano 
derailers have much lower actuation ratios, driven (I hypothesize) by a desire 
to increase the amount of cable pull per shift and, consequently, increase the 
tolerance for imperfections in cable movement. Campagnolo, interestingly, 
_increased_ the actuation ratio slightly when they went from “old” 9 speed to 
“new” 9 speed and later. Always marching to their own beat, those Italians.

My choice of shifters will depend on several factors, including the gearing, 
the derailer, whether I feel indexing is important, and whether I want to deal 
with the additional complication of handlebar-mounted shifters on a bike that 
might get rinko’d.

Re: [RBW] Re: how wide of wheels and tires will a specialized seqoia handle

2024-04-03 Thread 'William Watson' via RBW Owners Bunch
I have a 81 Sequoia built in 3Rensho's shop. Mine clears 33 Soma Supple 
Vitesse on 700c wheels with no fenders. I might try 35s at some point, but 
these are nice for now and I have other bikes with bigger tires. 

I thought I had heard the later years had more clearance, but I just read 
somewhere that perhaps the Merz version had steeper angles and less 
clearance so as not to compete with the Expedition.

Re: [RBW] how wide of wheels and tires will a specialized seqoia handle

2024-04-03 Thread Eric Daume
I have an ‘82 as well and it has good clearance, depending on the brakes
used. My current Superbe Pros have lots of room, while the previous Tektros
were tighter. The previous owner said he could fit 35mm actual tires, and
that looks possible (at least with the Suntour brakes)

Ted

So, you have settled on what your gearing and derailleur choices will be? 
 If yes, what exactly will they be?  What rear wheel OLD will you be using? 
 Will it be a cassette rear hub or a freewheel?  How many cogs in back, 
what cogs?  If it's a contemporary 10 or 11speed cassette width, have you 
confirmed your Suntour RD will sweep that horizontal distance?  What 
shifters will you use?

Re: [RBW] Re: Gearing Choices

2024-04-03 Thread Patrick Moore
Piaw: It's easy and, thanks to AliExpress, relatively cheap to build your
own cassettes from loose parts -- at least, perhaps not for really huge
cogs. But a half step + granny could give me, anyway, nice close cruising
gears in the 75" to 60" range plus a downhill gear or two and some low
bailout gears.

I did this long ago for a commuter with 48/45 or 47/44 rings and a 7 speed
cassette, something like 13-32, half-stepping (more or less) the middle 5
cogs with cruising gears in the middle, and using the small for a downhill
gear and the big for a bailout gear:

25" wheel:
48 45
12 100
13 92 87
15 80 75
17 71 66
20 60 56
24 50 47
32 35

BTW, this shifted very nicely from hoods, ramps, and hooks with Kelley
Take-Offs, on pavement; would not want KTOs on bumpy dirt.


Generally speaking, though, with 9 cogs or more I prefer crossover, and
 I'll trade top high and bottom low for close middle ratios; with a 10
speed cassette giving many more possibilities and the new knobby 50 mm
Oracle Ridges requiring slightly lower sandy dirt gearing,  my Matthews
"road bike for (sandy) dirt" has a sub-compact plus granny:

28 1/2" wheel:
44 28
14 90
15 84
16 78
17 74
18 70
19 66
20 63 40
22 57 36
25 50 32
28 45 29

2024-04-03 Thread Piaw Na
I'm a big fan of half-step + granny for 7-speed rear cassettes and 
freewheels. I think I even wrote an article about it for the Rivendell 
Reader at one point (good luck digging it up!). What killed it for me was 
once cassettes got to the point where constructing your cassette was no 
longer supported or too much work, it was no longer practical.

Around here in the Bay Area, I simply decided to go for the lowest gear 
possible, and live with suboptimal flat riding gearing. The reason for this 
is even if I can climb a 20% grade when fresh on a 34x34 drivetrain, there 
will come a day when I have to climb that grade tired, or when carrying a 
load, or when I just not feeling like working that hard. Going 1mph slower 
on the flat by contrast just doesn't bother me that much. Just the other 
day I took my wife on a ride up the Wallace Stegner trail. We'd hiked that 
trail a couple of times but to my surprise my computer read a 20% grade. 
Her ebike had to work to get over it and I got into my 40x51. Having that 
on my bike makes me more likely to ride trails like that. Those who live in 
places where 20+% grades are unusual or cannot be found probably won't 
bother with my low gears.

Re: [RBW] Re: How do I know when a saddle fits?

2024-04-03 Thread 'Steven Seelig' via RBW Owners Bunch
A lot of great input here.  I think I now know how individual an issue this 
can be just from the comments.

For me, just recently it has turned out that all those Brooks C17s I have 
ON ALL MY BIKEs are no longer working for me.  This may be TMI but it turns 
out that because of their shape, my sitbone locates a bit forward of the 
rear of the saddle and that causes paid for me as cocsysx bashes into the 
raises rear of the saddle.  Not really a problem if I am riding on flat 
ground.  When I do need more umps, and I push toward the back of the 
saddle, that is when I am enduring pain.  I am working with a physical 
therapist to figure out if this is because of a weak pelvic floor.

What I have discovered is that the whole saddle business is rapidly 
evolving, with such things as 3D printed saddles, men's specific Terry 
seats (from a company that made its name making women's saddles), the major 
players like Trek and Specialized have actual heat mapping that would help 
explain your hot spots - and those are just a few examples.  For me, I have 
learned that many of the newer saddle that have gaps for your dainty bits 
also have space to the rear so that your sitbone may reside on the saddle 
while the rear part of your rear may hang out back.  I am testing saddles 
with that profile and things look promising.

No, I am not selling all those Brooks quite yet - don't get any ideas.

[RBW] Gearing Choices

2024-04-03 Thread Ted Durant
This might be a fairly long post, apologies in advance, and just skip past 
it or delete if you’re not interested in another treatise on gearing.

I’m in line for a fancy custom bike and I’ve spent an inordinate amount of 
time (it’s good to be retired) working on the gearing. Part of the quest is 
that I want a normal-looking silver rear derailer. Given the direction the 
industry is headed, and the uncertainty over the fate of the OM-1, this has 
been keeping me up at night.

So, gearing….   I’ll start with the three basic quantitative decisions: 1) 
high and low gear, 2) how many cogs and chainrings, and 3) the spacing 
between each gear. In some sense you could say that (3) is dictated by (1) 
and (2), but a significant question is whether you want equal spacing 
across all gears or closer spacing in some and wider in others.

Starting with (1), we are immediately faced with how to measure a gear. 
Most people who spend any time with this still use “gear inches” which, 
while a quaint throwback to high-wheelers, is a reasonably intuitive metric 
and lots of people immediately know what you mean when you say you’re 
riding a 67” gear. For reference, in the 1980’s the standard 12-speed was 
set up with a 53/39 crankset and something like a 13-24 set of cogs in 
back. That’s a high gear (on 700x25c tires) of 108” and a low of 43”. 

St. Sheldon annointed the Gain Ratio as the preferred metric, and for a 
long time that’s what I tried to follow. It adds in the effect of crank 
length, and you can think of it as the distance the bike travels relative 
to how far your feet travel. That 80’s 12 speed, with a 170mm crank, has a 
high Gain Ratio of 8.1 and a low of 3.2. It’s clever and theoretically 
superior, and I know that a Gain Ratio a bit under 5.0 is my normal gear, 
but it just hasn’t taken root for me.

A simpler ratio would be the gear ratio itself, which doesn’t take into 
account wheel size or crank length. It’s pretty easy to calculate that a 
52x13 is 4x, and 39x13 is 3x, and 39x24 is, well, a bit more than 1.5x. 
Different wheel sizes may or may not matter to you.

In my noodling on this I had a blinding flash of the obvious. What really 
matters is how fast (or slow) I am going. For that, of course, I need to 
know the cadence I am riding at. Everyone has (this is scientifically 
proven, seriously) a preferred cadence, and a comfortable range around that 
cadence. There is a pretty wide range among people of their preferred 
cadence and range. So, I decided on my comfortable cadence and range, and 
now I measure gears (taking into account wheel size) in the speed I am 
going at my comfortable cadence. 

The notion of comfortable cadence range then can play a major role in 
determining how much spacing you want between gears. For example, my 
comfortable cadence is around 87 rpm (aside - I’ve gone to shorter cranks), 
and the range is 75 - 100. An ideal shift for me is one that takes me from 
the limits of that range back to the center, which is a 14% difference. 
(footnote: I measure differences as the natural log of the ratio, happy to 
explain why but I don’t think it’s important here.)

Alas, we are limited to 1-tooth differences, and sometimes 2-tooth 
differences. And while a 10-11 change is 9.5%, a 14-15 change is 6.9%. The 
evolution to smaller smallest cogs in back has significantly increased the 
challenge to building a set of cogs with consistent differences across the 
range. If you want a 14% change, you’re kind of stuck down at the small end 
of the cogs, choosing between 10% or 20%. Even starting with a 12 tooth cog 
helps considerably, as the 12-14 jump is 15.4%, which is very close to 
ideal. On the other hand, starting with a larger small cog means having to 
go to even larger large cogs to get a desired low gear, or widening the gap 
in front, or going to a triple. 

Alright, so there are essentially two approaches to using multiple 
chainrings to arrive at a desired range of gears with even steps: crossover 
and half-step. In a crossover system, you try for even, acceptable steps 
between cogs in back, and when you run out of gears in back you cross over 
to the other chainring. In a half-step system, you try for even steps that 
are twice the desired difference and the chainring difference half of that. 
So, you are making rough adjustments in back and fine adjustments up front. 
A variation on that is to add a third, small chainring, known as “half-step 
plus granny”, in which you have a bunch of evenly spaced gears and then a 
handful of wider-spaced gears down low..

The development of higher cog counts in back has made crossover setups the 
standard. However, as John Allen has pointed out, the accompanying 
development of more flexible chains has made half-step gearing potentially 
a better option. If you were to build an ideal half-step system, say 
starting from 11 teeth and using 18% increments, you’d go from 11 to 34 in 
7 cogs, 41 in 8, and 49 in 9. If you combined

As a matter of fact, I've never used my Miche 10 sp cassettes with a 10 sp
chain but I suppose those must also work. (Since I built those Miche 10 sp
cassettes, I've used a chain "1 generation later" than the cassette because
web scuttlebutt says that this promotes crisper shifting. At least, I have
found no evidence to the contrary -- shifting is wonderful, as it is with
the same chain and the cassette made from 1.6 mm Shimano cogs and the same
2 mm spacers.)

Bill,

I also have a brown Gran Premio! I especially like the Suntour symmetric
shifters. Univega was the brand sold in my childhood bike store, so when I
saw mine in a used bike shop, I had to have it. They'll always have a soft
spot in my heart. If I were to ride mine in the CA Eroica, I think I'd need
some lower gearing, maybe the Velo Orange 46-30 crankset.

Cheers,
Keith

Thanks, Ted. I reviewed Sheldon's chart and saw these measurements for 7
thru 10; where did you find the 11 sp measurements?

I'll be interested in you related post.

The 10 sp Miche cogs are odd. The Shimano 10 speeds measure 1.6 mm wide
across the cog, the Miche ones measure 1.6 mm at the teeth but ~1.8 mm or
so below tooth level; thus the 2 mm spacers, I guess. At any rate, an 11
speed chain works fine on those 10 sp Miche cogs.

Yes, someone please assemble a complete chart for at least Shimano
cassettes, freehub bodies, cogs, spaces, and chains.

FWIW, the center-center spacing for Shimano cogs is:

7sp 5.00
8sp 4.80
9sp 4.35
10sp 3.95
11sp Road 3.69
11sp MTB 3.90

Sorry, I don’t have 12 and 13. 

Cog + spacer widths need to add to those numbers. Theoretically you can use 
thinner cogs than spec with wider spacers, but you would run into trouble 
with chain fit using thicker cogs with thinner spacers. If somebody finds 
or assembles a complete table of cog and spacer thickness spec’s, that 
would be a significant contribution to humankind.

I’ll be posting on a related topic, soon.
