My 10-year old bike just broke down and I decided to start looking for a new one. I've only been using it for non-hardcore trails and off-road stuff for 6 months (hence the breakdown).

The Cube Aim and the Trek 3700 Disc are in the same price range, but I'm willing to go for something in the Trek 3900 Disc price range if it's worth it.

Should I get the Aim and not worry about the disc brakes? Are those really as important? What do you guys think?
