A legend sharpened to a new level of perfection. Providing the ideal symbiosis of lightweight, stiffness and performance. and finally out there to set new standards in professional cycling.
Shifting has been even further improved by creating an even more rigid (and lighter) aluminum carrier unit along with re-engineered teeth profile. Cassette design is lighter as Shimano has developed a super lightweight and rigid aluminum cassette sprocket carrier. The largest four cogs are titanium and weight is reduced by 10 grams. Available combinations will be: 11-21T, 11-23T, 11-25T, 11-27T, 11-28T, 12-23T, 12-25T, 12-27T.
Shimano 10-speed cassettes fit on Shimano 9speed cassette hubs, but a super narrow 10speed chain is needed!
