|Hi. I'm trying to finalize my 'cross bike and need some help w/ gearing. I've heard reports of 42-20 and 40-20. Anyone have any input? Thanks!

|This was thrashed out a little while ago (2 weeks?) over on the components and, I think, general board - have a search.
Try www.32sixteen.com for gear chart and gen info.
42:16 is a good general training gear for light ups and downs.

|is this going to be for cross racing or general trail riding? Here's what I use. 42x15 for road/fixed gear, 38x17 for CX racing, 38x19 or 38x20 for trail riding that involves lots of climbing, more technical riding etc., much like a standard 2:1 MTB gearing.
42:20 sounds good, I find that if you go to low you'll spin out a lot as most cross courses have some long stretches where you need to be able to push a bigger gear to keep up the pace, unless you can spin like a madman. In thick mud I always geared down a bit too because you can't slog through all the crap in a big gear all the time.

|I've ridden 36/18 on two very different courses in the past two weeks and I think it's a good compromise. It will feel way too small in warmups, and way too big on the eighth lap.
I wouldn't go much bigger unless your course is super fast, or you're just a monster.
For training on flat dirt trails (Des Plaines river trail for any Chicagoans in here) I like 42/18

|I'm running 43/19 on my Gunnar Streetdog and it does fine for most cross stuff hear in the Bay Area.|| |
