I run a 44-28 on my Hillborne with an 11-32 in the rear and like the
combination very much.
I found this article from Jan Heine very helpful, particularly his advice
on selecting the Base, High and Low gears.

Ah. Thanks, Steve. I'm too much of a Fred to be a Fred on Zwift. Grin.
With abandon,

I've no idea what Zwift is. But riding single speed helped me greatly
expand my range per gear (duh). It increased my power and technique with
low RPM high torque pedaling (climbing) and it increased my spinning
ability on descents. Perhaps ride at least a ride a week in poser single
speed

A 36 front 11 rear gives 87GI for a 700Cx28. You may want a higher top
gear. However, the front shifting would be good, only a 10T difference,
like 52 to 42.

This is similar to my issue - I have 48/30 up front, with a 11-28 rear
(11,12,13,14,15,17,19,21,24,28). I think I want to buy a 36 chainring but

or if I should get a different compact double and save the 48/30 for my
Garth,
I suppose, sure. Though really its the gear (ratio of chainring over cog)
that you don't want, so you can blame it on either the cog or the ring. Are
you configuring rings around a cog you don't want, or cogs around a ring
you don't want? I suppose either point of view is equally valid.
While I am not familiar with every type of casette, but are not the
smallest/lock ring cogs individual and easily replaced with a 12 or whatever on
most cassettes ? Ceratainly a bit more simple than trying to configure rings
around a cog/cogs you do not want or need. I would rather have gears

John,
Thanks for pointing out that TA makes 41t chainrings. Im well aware of GPs
writings re too big gears. One of my bikes currently has Silver 25 and 43
rings sandwiching a TA 33 on Sugino arms I got from RBW. Prior to that it
was set up as a 26/40 with chain guard, and before that as a

I used Jim Youngs Gear Calculator for the GI values for a 7000x32.

You asked; (does anybody make 110BCD 41t chainrings?) Yes TA
Specialties and RBW has 43T Silver and a 40T Sugino. GP has a good write
up in the Silver ring section
Hey John,
My tone was inappropriate, and I got way off the point right off the bat.
My bad, I apologize.
I agree that 98 to 100 inches for a top gear is reasonable advice. Many
riders probably find a top gear like that ideal.
However, as you note, YMMV. I think many riders would find a top
Ted
I am sorry, By 52-14 I meant a 52T large ring and 14T smallest cog. This
gives a 98 to 100GI value for 27x1" to 27x1-1/4" (common in the 70's) and
also for 700x25 to 700x32. the 2GI difference is insignificant.
The 100GI top value is the same as Schwinn explained in the their 70's
John, I don't think there were ever any "... 52-14 days of 130BCD cranks".
A nerdy quibble I know, but please bear with me ...
I believe the venerable 52-14 high gear dates from early 144 bcd crank days
when Campi ruled and the Japanese copied Campi, when a common racing

I would get a crank to give 100GI with existing 11-30 for Large ring/small
cog or change the cassette to get 100GI for large ring/small cog, for
example
Current Crank & Existing Cassette, 46-11 = 113GI, pretty high for all but
pros
Current Crank & New Cassette, 46-12 = 103GI,
"For me, a 50/34 left me riding cross-chained too often."
If I had a 50/34 crank I think I would immediately swap the 34 for a 36.
When I went from 53/42 to 53/39 it took a while to get used to the bigger
jump with the with the 14 vs 11 tooth difference between rings. I doubt I

mountainous areas of VT,NH and MA. I used my 52x12 gear often on

I believe your numbers are off. The cutoff point is easily twice that.
Yes they could very well be wrong. That info was just for going downhill. I

Sounds like only 4 issues here:
1. Can he keep up on club ride with whatever crankset he's going to use?
2. If he can't keep up he's going to have to train to keep up. Is he willing

Form my personal experience with racing oriented club rides "they" are
wrong, at least in the context of fast club riding. Groups like that
If you can't push a 50-36 and keep up in club rides you're going to have to
train in order to do it. If you're not the kind of person to train then:

What about the 50/34 does not suit your needs?
For me, a 50/34 left me riding cross-chained too often. I have since used
46/30, 44/28 and 42/26 combinations that let me run on the big ring in the
middle of the cassette most of the time, with the small ring as a bail out
when I have to climb
It may help to think about how what you have that matches what you are
considering feels.
A 46x11 high gear will be the same as the 50x12 that you probably currently
have as a 2nd highest gear. Is that high enough for you?
A 30x30 low gear would, of course, be one to one. Do you have a one to
