I'm looking at getting a new bike mostly for commuting. Two bikes I'm interested in are a Gary Fisher Mendota and a Rocky Mountain CXD. The Mendota is similar to the bike that it's replacing, which is a RMB RC50. The Mendota is a nice looking bike and has a pretty good drivetrain. The CXD is a cyclocross bike with disc brakes. I like the idea of the CXD in that it would be a bit faster and would also be suitable for some winter or bad weather road rides. My biggest gripe against the RC50 was that it's a bit slow, especially in winds. My commute will vary from 10km to 15km each way. The 15km route includes a 3km hill at 9% grade.

I'm also looking at a Kona Dew Deluxe, Trek Valencia, and a few other similar bikes. The price point on the urban bikes is better, but I'm not sure if they are the right ticket for longer commutes.

I guess there is no real right or wrong but I would like to hear some other people's opinions.

thanks
