ShimanoUltegra CS-R8000 11 Speed Cassette(Return to Product Page)

Best for uphill.

I use this cassette on my Specialized S-Works and it shifts great and lasts along time. I. am replacing a similar product which provided me 30,000 miles over the last 4 years.

Shimano Ultegra is installed on all my bikes. Never fails me.

Just updated my Trek Madone with this wider range cassette. It is perfect!

This cassette works like a dream. Smooth shifting and I always seem to have the gear I need. Nice!

This cassette makes my rides more enjoyable, I expect it to last a long time given Shimanos reputation.

I use it for mountain climbing. Long grades above 10% require me to stand in a 34x28, so this just makes the difference between sitting and standing.

Im really enjoying this new cassette for climbing. Im running this 11-30 with a SRAM RED mid compact setup. Very smooth shifting.

The Ultegra cassette has always been the best balance of price and performance. With the release of the 8000 series comes the new 11-30 cassette, which I really loved for cyclocross. Having the 30t was nice to have on steep courses over the 28 but only a little bit heavier.

Excellent substitute for dura ace with better wear characteristics and only a slight wieght penalty, much lighter on the wallet too.

I purchased the Ultegra cassette to add to the Shimano Ultegra wheels that I had ordered from the vendor.

Very pleased with the cassette and wheels. No problem installing on bike.

Use the product on a Saris trainer. Works great.

About every 4th chain I replace my cassette, and this one does the job well.

Where is your bike works at an excellent job of getting me the product the product was great and the service was even better. I like their return policy

works well & easy to install
