Looking for some advise. I have the original Nashbar MTB. Very solid and comfortable (slightly heavy steel frame) non suspension frame. The bike does have really nice shimano thumb shifters, great canti brakes, very big and heavy combination handlebar stem, oversized brake levers. These oversized brake levers may be why the brakes work so great on this bike. It originally came as a 15 speed and now it is a 21 speed. Shifting works great on the bike as it is set up. Wheels have nutted axles. Holds a nice rack and fenders with a lot of clearance.
So the question is about upgrading to drop handle bars, different brakes and road tires, would this make this bike similiar to the Bruce Gordon BLT X? Also, would this be worthwhile in your opinion?
