My rear brake lever punctured my stock clutch cover during a recent tumble down the trail. I cant remember how I decided on the Pro Circuit cover but I did and have had no regrets. It fit perfectly and I have had no leaks so far (new gasket of course).
It has been through roughly 500 miles of aggressive woods riding so far and my boot has yet to rub through the finish. It looks the same as the day I installed it. I will definitely use again when I put a hole in this one.
