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...
