Steel plated teeth on the XT version provide greater durability, while strengthened aluminum teeth on the XTR version keep the weight down.The new cassette for 1x11 riders offers a super-wide 11-46T range providing optimal gear choices for Enduro riders. The target weight of the CS-M8000 cassette is 450g and it's designed to work across XTR and Deore XT platforms.To provide greater flexibility Shimano now introduce an 11-speed chain QUICK-LINK (SM-CN900-11). It is designed with tool-free assembly in mind for quick on-the-trail repairs, although for rapid assembly of multiple chains a professional assembly tool (TL-CN10) is also available.New gear combinations offered on new 2x11 and 3x10 cranksets are focused on lower gears for riders riding in steep mountainous areas. The DYNA-SIS 11 FC-MT700 34-24T crankset features HOLLOWTECH II crank arms. Meanwhile the 3x10 MT500 crankset provides 40-30-22T rings and a 2-piece crank arm with a stiff, solid and robust construction.BrakesSitting just below ACERA level, Shimano introduces two new non-series M365 and M315 hydraulic disc brakes. The M365 comes with a lighter aluminum lever and both brakes offer technology adopted from top-of-the-range disc brakes such as noise-free stable braking performance, and quick and clean bleeding.Complementing the new M365 and M315 disc brakes is a new lock ring style for 160mm or 180mm SM-RT10 rotors, designed to simplify handling and operation for workshops and manufacturers. Two new tools provide quick and easy maintenance for rotor installation, either the TL-FC36 outer serration wrench or the TL-LR11 inner serration socket tool.[ATTACH=full]16441[/ATTACH] [ATTACH=full]16442[/ATTACH][ATTACH=full]16443[/ATTACH]</blockquote>
