Our  Wide Range 10sp cassette is made for the MTB rider that needs just a little deeper climbing gear, but refuses to give up performance.  This is a full cassette and NOT an ‘Expander Adaptor.’  This is a great shifting, no sacrifice, no compromise ‘Wide-Range’ 10sp MTB cassette, that you could use an unmodified 10sp MTB rear derailleur with.

30 DAY GUARANTEE : Don’t stress, purchase with confidence.
