My Specialized hard rock needs some new tires. The current ones are 26"x2" specialized fast trak LK's. I do like them but they are a bit bulky for my liking. I generally use my bike for 10ish mile rides on tar and chip roads or gravel... they are pretty bumpy roads. Also trails that I ride are generally gravel and fairly compacted. Any thoughts on what I should be looking at for my next tire?
