I'm fascinated how the double crankset in Shimano's newish gravel group,
GRX, is 48/31.

I think they should have done 46/31, but still good.

My gearing seems to have pretty much standardized around using 42/29
chainrings, mostly on 94BCD cranks, but I also have a couple of pairs
of Middleburn RS7 cranks using their Duo chainrings in the same sizes.
For cassettes, I use 11-34 for bikes where I'm not carrying much of a
load, and 11-40 for bikes where I'm potentially carrying a touring
load. I find that 42x11 is good for a bit over 50kph down a hill -
anything more than that, and I'm faster getting into a tuck than to
continue pedalling.

When I started road racing in the 1970s, the standard top gear on a
racing bike was 52x13, which is exactly the same gear size as 44x11.
Riders won the TdF on that - so I get pretty amused when non-racing
cyclists claim they need a bigger gear than that...

 Perhaps the clarity of my hindsight is clouded by the pink haze of
nostalgia (or the purple haze of something else), but IIRC, the original XTs
and clones, from the late '80s and early '90s, those that took the 122.5 mm
bb spindle, had a Q of about 150 mm. 158 is to wide for my taste -- I feel

2010-03-06 Thread cyclotourist

I'm really happy with my 50/34 X 12-30 set up. From memory, I think I use
the top six gears with the big ring, and the bottom five with the small
ring. Pretty minimal crossover with that set up. The low 34X30 takes me
just about anywhere I need to go, but the 50X12 pretty much never gets
used. I should actually move to a 48T or even 45T big ring.

On Sat, Mar 6, 2010 at 7:09 AM, Bill M. bmenn...@comcast.net wrote:

The ugly crossover is why I ditched the 50/34 on my commuter, and went
back to a 46/36/24 triple. I have no use for the 24 on my flat
commute, but the shifting pattern is nicer. When I bought a brand-new
Campy group for my go-fast I went with 53/39 x 13-29 instead of 50/34
x 12-26 - similar gearing, but a nicer shift pattern. The club riders
with compacts always seem to be riding cross-chained.

I don't think the biggest issue is how it will shift. After all

shifting pattern gets very awkward when you go from 14 to 16. At 14
the next gear is typically two cogs away. At 16 your in no mans land,
and at 18 and above the next gear is at the other end of the
cassette. I really like a 48/34 and could probably get along with a
44/30, but I think for rings below that I would prefer to have the
triple to widen the range without having to work so hard finding the
next gear.

Yes, the cross-over is the Achilles Heel of wide range doubles. For
many recreational riders, the cross-over on common compact doubles
spec'd for racers falls right in the middle of the cruising range.

I used my wide range double as a single with a bailout; with 9 cogs for the
44, 9/10 of what I needed required only rear shifts. And, I set up the outer
and the cogset for a pretty straight chainline in the cruising gears. With
nine or 10 cogs in back, one ring is plenty for everything except loaded
touring (I imagine) and steep off road climbs; after all, a 46X32 with a
typical 700c wheel gives a 39 low.

While it may sound crazy, I often find myself in the highest gear on
most of my bikes. I'm not a racer, but I really do enjoy a lower
cadence mash on the flats and downhills and the occasional low grade
hill. I also like being able to overtake the SF fixie riders who pedal
at insanely high cadences while I'm smiling and grinding at a moderate
pace. :) For reference the higher gearing I'm referring to is:

700C x 32mm: 46x12 (Romulus)
700C x 27mm: 53x13 (RB-1)
650B x 36mm: 50x11 (650B Sequoia)

…though I admit the last one is too high and impractical, especially
so for an upright city hauler bike. ;)

IMO a workable wide-range double uses the small ring only as a bail-

Something like 44/24 x 12-xx would work pretty well for me.

Wider Q's have been recommend to help me deal w/ IBT, but it's hard to bring
myself to doing it after I've worked hard (and spent $$$) to get as narrow
as possible!!! :-)

Those Ritcheys are nice.  $200 doesn't sound bad for NOS considering what's
out there.  I don't now what the RF Trubines look like, but guessing based
on what I've seen from them...

 and I know they are a bit techo... but the RaceFace Turbines have a
 fairly narrow Q.

 I guess I'm a lucky one... the wider Q works better for me.

 Even though I can rider wider Q's... I'm a bit of a old small BCD

 Campy Olympus and a Stronglight 300lx  all square tapers.

With my 46-30 crank and 12-28 cassette, I can use all 8 cogs in the
big ring and all but the 1213 in the small ring. Best gearing setup
I've ever had!
I can do even fairly hilly rides in the big ring and there's just
enough overlap in the middle of the range that I don't shift the front
very much.

for everything except loaded touring (I imagine) and steep off road
climbs; after all, a 46X32 with a typical 700c wheel gives a 39 low.

and at 18 and above the next gear is at the other end of the
cassette. I really like a 48/34 and could probably get along
with a

44/30, but I think for rings below that I would prefer to have the
triple to widen the range without having to work so hard finding
the

next gear.
