Extra for carbon wheel set
by RoboKrause

Duracesmooth as butter. Had to get an extra for my new carbon wheelset. Didnt wanna keep pulling off my cassette. I do find the 30t a nice bump for those 22% grades I never ride.

I needed a second set for my trainer and wanted to match exactly my bike to keep change over time at a minimum. Good price and high quality.

Shimano has always come out with great products and always cutting edge in technology. This cassette by far is the best cassette i've ever used, so light and gotta love that 30 gear...
