Shimano offers new wide-range cassette for 1×11
SHIMANO has been propagating two-by drivetrains in the past few years and their electronic XTR Di2 is arguably the most advanced 2-ring drivetrain available. With the market of enthusiast MTB riders moving increasingly towards one-by setups, SHIMANO is now catching up and offering a wide-range 11-46T cassette for both XT and XTR, as well as 1×11 specific chain rings. All the details in the press release:
Shimano has advanced the performance of its premium XTR and DEORE XT 1×11 mountain bike drivetrains while creating even more range and options as part of its Rider Tuned drivetrain philosophy. Also announced today were new gear combinations for 2×11 and 3×10 cranksets, new hydraulic disc brakes and a disc brake rotor lock ring promising easier assembly.
Advanced 1×11 premium MTB drivetrains
Shimano advanced its new XTR and Deore XT 1×11 chainrings with direct input from its elite mountain bike athletes, from cross-country to trail riders who tested in various conditions, seasons and locations around the globe. Efficient chain management was the goal and the new XTR (SM-CRM91 and DEORE XT (SM-CRM81) chain rings achieve this by introducing the Dynamic Chain Engagement (DCE) concept.
The modified tooth profile on the CRM91 and CRM81 DCE chain rings are designed to provide superior chain retention, lower driving noise and increased durability. Steel plated teeth on the XT version provide greater durability, while strengthened aluminum teeth on the XTR chainring reduces weight.
The 1×11 drivetrain range has been extended to a super-wide 11-46T range providing optimal gear choices for all-mountain riders and enduro racers. The new CS-M8000 cassette is compatible with XTR M9000 and DEORE XT M8000 drivetrains and has a target weight of 450g.
To simplify chain assembly, Shimano introduced a new tool-free 11-speed chain QUICK-LINK (SM-CN900-11) for quick, on-the- trail repairs. The SM-CN900-11 link is compatible with all 11- speed Shimano chains. For rapid assembly of multiple chains a professional assembly tool (TL-CN10) is also available.
