53x13, n00bs!

thats funny i ride 54x13

Man, I feel like such a girl, now! I guess it's time to HTFU and move to 55x12.

What is the acceleration like with those 53:13 and 54:13 gearings ?

Or is it just to impress the peeps on the corner ?

This is my '73 Carlton running a 52:14 (100 gear inches) but for the real world the 52:18 (77 gear inches) I am running now works so much better cause the real world has hills, wind, and traffic.

bonechlling is lying

he rides trials 1:1

whoops

edit - Total of 1,694.3 gear inches!!! Yeah!

What are you using for a chainring? I am want to run 47/17 on my nicer bike. I have a 47T Rocket ring on my beater, but I would like something a bit nicer for my nicer bike. However, I am not really all that into dropping a ton of money on it.

Current setup is 46x17. I can climb any hill in this, unless it is 5 mile/8% grade. Note, I am in the hilly portion of WI, it is the land of monster rollers. Group rides are done with 48x17, but I am toast afterwards, and its hard on the knees.

I had a track frame setup with 53x16 as a fixed gear TT bike. Complete with aerobars, SPD-SL's, and a front brake. I could ride it around, but it was intended for the 27-29 mph speeds (100-110 rpm) encountered in a 40k TT. Very hard to stop brakeless from 30+ mph.

Those who say they ride 54-13 or similar are high on the bull-#$%^ meter. It does look bad ass though!

Cheers~

46/16 Ss

It's true. My freewheel is also my bottom bracket.

how do you think i feel with my 40 13

just inadequate

Winter (snow): 39 x 18 w 26" wheels
otherwise: 44 x 16 w 27" wheels
and
40 x 12 w 20" wheels

46/16

42x15

42/17 (66GI I think) on my crappy beater conversion w/ platforms.

Once I get my IRO frame in, it'll be running 46/17 (~72GI). I've a 52T chainring as an option too, but I'd prefer a 19 or 18T cog on the back for that ideally.

50/34 crank with 12-27 cassette.

46x19 currently.
Spring build is 46x17

52x18, 76.2 gear inches, good all around for hills flats, hot cold. My max speed was 36mph on it, at 159rpm

The best ratio is one that results in the top of your chain to be parallel to the road.

For me my combo is 48:15

I ride a 48x18 (70")which works out to 100rpm at 20mph. I've started doing group rides more often on it now and am thinking about moving up to a 76-78" to make the group pace a little easier.

46/17, seems to work well for my everyday commuting.

46/17, 71-ish GI. The right happy medium for my commutes and long rides with modest hills. 46/14, 86 GI was killing my thirty-something knees.

39x14t

48/16 and 46/15
