Drivetrain & Brakes
This chain has been my go-to chain for use on the multiple E-MTB's I have owned. This chain provides many miles of smooth reliable performance and precise shifting. I just purchased a new Specialized Turbo Levo E-MTB and replaced the the new GX chain with this one and immediately noticed the difference. This PCXX1 chain is much quieter and the drive train shifts smoother. Plus, I know from thousands of miles of experience with these chains that they're extremely durable and reliable in all weather and terrain conditions. Highly recommend this high quality chain!
I've been using this 10 speed 12-25 cassette for years. Most of my shifts are only 1 tooth, which makes for instant & smooth shifting. So glad Western Bikeworks still stocks this in this age of 12 speed popularity.
2017 Specialized Roubaix just passed 38,000 miles and this is the third back rotor for the bike. I live in Sparks, Nevada, and enjoy many significant downhill decents in the area. Good braking is a necesity when decending from Ebbetts and Monitor Passes, and I find these rotors prevent brake fade. I weigh 200 lbs and the back rotor is only 140 mm so it gets severly punished. I stayed with the Dura Ace model as I prefer black to the silver of the Ultegra version. It will last for several years so I am willing to pay a little extra. Overall a good rotor.
