cheap hardware
everything fits good. my only problem is the cheap hardware. 1 bolt the threads all stripped off, and also the heads catch on my pedals. so i have to go to the hardware store and look for a couple better bolts. not a big issue. also the plastic roller wheel seems rather cheap, not sure how long its gonna hold up. for the price i guess it was worth it.

The best!
I struggled with many chain tensioners thinking ok i got it this time...? Dont kid yourself.. spring-loaded tensioners are the best solution for sure! The one thing I needed to do.. I grinded the bolt heads down about half.. so crank peddle can pass freely.. Use double nuts on the bolt harnessing flex part, to lock tight but still loose enough for tensioner to flex.. Thats it.. Works great!
