Query: Flimsy, Hard to Remove.

I got a set of these hoping they would work well on my '09 Valencia. Unfortunately, the hardware included barely fits and the rear fender clip interfered with the front-derailleur cable. But even after getting the fenders to fit, they would wiggle around and even bounce on the wheel, which is far from safe. And the promise of clipping "on and off in seconds" is completely false. The front fender requires unscrewing a thumb nut and the rear fender gets caught in the plastic clip and is near impossible to slide out.I trashed these and went with a set of Bontrager Satellite fenders ($25 at most dealers or online) which are much sturdier, have a better clip-on system with quick-release levers, and even fit into my messenger bag to take with me.
