KCNC Ti Cassette Details
This KCNC 10 speed Shimano- and Sram-compatible cassette is ingeniously designed to take full advantage of its titanium and aluminum construction to provide a low overall weight and a reasonable wear life. These cassettes features a two-piece design; the eight largest cogs are mounted to a 7075 aluminum carrier, while the two smallest cogs are machined from a single piece of titanium. A benefit of this design is that no cog has independent contact with the freehub body, removing the possibility of damage to the freehub splines and simplifying installation and removal. The KCNC titanium cassette rivals the weight of other aftermarket aluminum cassettes, while providing greatly improved durability and a longer life span.
Installation and removal of a KCNC cassette is simple, requiring no special tools beyond the chain whip and Shimano locking tool that are required of most other cassettes. The 11-38 cassette is provided with two longer B-Axle units to fit either XT RD-M780 or XTR RD-M980/985 Shimano Shadow series rear derailleurs. In cases where the rear derailleur does not fully clear the 38 tooth cog, one of these units may be installed to provide adequate clearance. Refer to either your local bike shop or the Shimano Shadow tech doc when replacing the B-Axle Assembly.
