46x17 is for heathens.

stevo_com whats the average GI on here anyway?

46x17 is somewhere between 71" and 72" depending on your mathematical sensibilities, and therefore is equivalent to the following GI:

Table 3 - High Glycaemic Index (GI) Foods

Mashed potato 70
White bread 70
Watermelon 72
Swede 72
Bagel 72

65-75" gear around Lundun.

Spinners are grinners.

stevo_com 52:16, but I'm a wuss and have a brake

52:16 is that all, I used to run 60:14...

okay, okay, so it was on a bike with small wheels meaning only a 72" gear...

but it sounds impressive though.

Nah, it's like a golf handicap. Lower gear inch numbers are more impressive.

My current bike is also my first fixed. quote]

hence the absurd gear?

When I built it last year I just used the crankset I had lying around and the cheapest cog I could get my hands on and ended up with that 52-20. Then a friend gave me a 16T and it seemed more comfortable so I splashed out on a Surly one (which was subsequently nicked, waiting on a Dura-ace replacement).

hippy, yeah, was considering a 46T chainring with the new crankset so that would be about 75" I reckon, will have to wait for funds though. my current crankset has the chainring fixed to the right crank so it wouldn't be just a case of a new ring.

When I was back home (Northern Ireland) visiting family and friends over christmas, a friend and I 'fixed' a crappy cheap MTB that someone had given to my dad. we just, again, used what we had lying around. could only find a 13T cog so ground the bigger two rings off another MTB's chainset leaving the granny ring (28T 56"), looks a bit silly having such a small drive train but coupled with the high BB gives shit loads of clearance. tons of fun to boot.

before anyone comments, there's a front brake because the rear hub is a regular freewheel hub and the cog is too small to allow for a BB lockring.
