SainStyle NV-5 HS1 Mechanical Bike 160mm Rotor Brake Disc Kit for Mountain Bicycle

They work Great!Just make sure not to install them on backwards like I did.One is designed for the front brake, and one for the back. It didn't have directions on which is which until I realized that it wasn't working properly, and that I spent half an hour putting them on wrong.but since I put it on correctly it works Perfect!Its not like brembo Brakes on cars, but it gets the job done. and thats what matters

I had a relatively painless install on my IS fork. My wheel had holes for the 6 screws to install the discus and everything went smoothly. I've ridden a few times down a hill where I'd apply the brakes for a minute continuously and I haven't seen any anomalies on the discus or the braking unit.5/2/2014: Put loctite on your bolts when securing rotor. That way your rotor bolts won't be shaken loose while you ride.

Installed these on a circa 2005 Specialized mountain bike that came with cantilever brakes but had the studs and hubs for discs. Installation was smooth and easy and after some fiddling and a short learning curve, got them adjusted nicely. quite pleased for mechanical disc brakes.

I was nervous at first about buying these. I wondered if I could upgrade from caliper brakes to disc brakes? It turned out I can. I will buy these again in a half of a heart beat

The caliper and disc are very functional and of good quality for the price.

Works as well as a more expensive set. Easy to install and adjust.

They work, I think the price has gone up since I bought them, but simple for what I need them for, I still prefer coaster and drum brakes.

good
