As a note before the question, you all can be expecting a fun/ghetto/beater cyclo build in the near future.

I'm in the process of getting all of the various parts and pieces I need to start my build and I'm totally lost on the gearing I want to run. This bike will be used on some light trails and hopefully some CX comps in the fall so I'm thinking I'm going to need to gear it considerably lower than would be best suited for street riding.

I run 48x17 on my other ride and push it no problem all day long, but I'm thinking about running 39x16 or 39x17 on the CX build. Whats you all's take? Too deep? Way off base? The reason for the 39t, which I know is lower than most would choose, is because I already have it.

Like I said before when the parts roll in I'll start the build thread
