I have a Trek 930 Singletrack that I've run into the ground a bit commuting daily in NYC. Rims and breaks are shot, seat is torn, etc... I'm looking at a Kona Dr. Dew or as a serious reach, a Jamis Coda Elite. Does anyone recommend instead keeping my trusty steel trek frame and upgrading most of the components? (wheels, disc breaks, derailleurs, etc.) I feel like I could have an almost new bike at half the cost of the above models, without a flashy new frame to go with it. Thanks.
