I guess I have to go buy some chain tensioners soon, becuase if I case a tabletop on the track, the rear wheel slides forward ever so much and the chain gets loose. The bike is overall a fine value, and I am impressed by the geometry as well as the parts pick. Pretty amazing frame, fork, cranks and components for so cheap. The seat has already ripped after a few minor bails, and the rims aren't the best, but they'll do until I have to replace them. Great cranks,Light body, strong body,seat, Great Brakes.
Cranks get loose every once in a while, grips,pedals, rims.
This bike is good but could be great with a few minor adjustments. Not good for doing 180's. Alot of thrust. Not for people who like to sit alot while they ride. I think it is a good buy.
