ShimanoXTR CS-M9001 11-Speed Cassette(Return to Product Page)

Light, accurate shifting, Shimano makes great stuff!

It works on road bikes without even having to use a hangar extender (Woflink etc), just tighten the b-screw and there's plenty of space. As a bigger girl I couldn't get up long steep mountain grades (>12% for a mile or more) in the saddle without this thing

If you're looking for big climbing gears and willing to spend the money and don't mind the wider gaps in gearing, get this instead of the Ultegra 11-34 cassette since this provides a huge range and weighs a couple grams less

I do big climbs on my road bike and use this cassette with a medium cage Shimano derailleur and Wolftooth Roadlink. It works great! Couldnt be happier with this light weight cassette. This XTR cassette is an amazing piece of engineering and technology.
