SRAM XG-1295 Eagle 12 Speed Cassette Freedom Free at last. You are all now welcome to toss all front derailleurs right out the window. The SRAM XG-1295 Eagle cassette, with its whopping 10 to 50 tooth 12 speed range, has taken all reasons to continue fussing about with a 2x drivetrain and pushed them out of the nest. This cassette now offers riders a 500% gear range which is 20% more than any other current system out there. It carries with it X-Dome technologies which have, for quite some time now been touted as providing the strongest cassettes on the market. Compatible with XD Driver bodies, sports new shifting characteristics and better chain retention.

" - Chris Hilton Features SRAM's cassette manufacturing technology provides the greatest durability and lightest weight.
