Ok, my spouse's bike was pretty cheap. Fuji Crosstown. Had it for 3 years. Get's used 4 times a week. 8 miles each time.
The problem is that the seat keeps going down. It has a quickset style seat clamp, which I tighten down about as hard as my hand can tolerate, but 2 days later it needs to be done again. We've replaced the seat post hoping that that would work, but no magic.
Would a different seat clamp, like one that uses a allen wrench, work better? What can we do to keep the seat in place?
