Shimano just unveiled its newest iteration of the flagship XTR mountain bike component group in the form of the 11-speed XTR M9000 and M9020 series of components, and Cyclocross Magazine grabbed an early look before the official launch today. The major changes include a single 11-40 11-speed cassette that works with existing 10-speed (and thus 8 and 9-speed) hubs, a single chainring option, new carbon and carbon laminate wheels, and as with Shimano’s new 11-speed road groups, a focus on light action shifting.
One component not on display during the launch was the XTR pedals, as we’ve been anticipating updates to the flagship SPD pedal after spotting Sven Nys’ modified XTR M980 pedals at Cross Vegas.

IRVINE, Calif. (April 12, 2014) — Shimano today introduced new XTR M9000, its most advanced XTR mountain bike components and wheels to date. With this totally new XTR line available in both Race and Trail “Rider Tuned” product families, Shimano leverages its 22 years of engineering leadership producing the industry’s highest performing mountain bike component group. Inspired by the versatility and capability of today’s riders and the terrain they tackle, M9000 offers refined and tested solutions engineered for the way they ride.
Drivetrain System: “Rhythm and range” define the 11-speed drivetrain Shimano’s unrivalled legacy in producing bicycle drivetrains is evident with the XTR M9000’s most notable rider benefit: ensuring pedaling rhythm. New XTR M9000 provides range and ensures rhythm for diverse riding styles and terrain to create smooth, harmonic pedalling – the ultimate goal of a drivetrain. The XTR M9000 drivetrain system maintains riders’ rhythm thanks to meticulously selected close step gearing configurations of the cassette and crank.
XTR FC-M9000 Race and FC-M9020 Trail cranks are modular, creating a Rider Tuned platform whereby single and double chain rings can be used on the same crank arm. XTR FC-M9000 crank sets debut the most advanced mountain bike chain rings ever produced that utilize combined titanium, carbon and aluminium materials. Dedicated XTR 1x chain rings debut proprietary chain ring retention technology in a tooth profile that eliminates the need for chain retention devices.
* XTR FC-M9000 Race cranks have a narrower 158mm Q-factor and utilize a lighter and stiffer 3D hollow bonded structure on the non-drive arm.
* XTR FC-M9020 Trail cranks are available in single, double and triple chaining configurations on the cold forged more durable, standard 168mm Q-factor crank arms.
* Chain ring configurations: Single (30T, 32T, 34T, 36T), double (34-24T, 36-26T, 38-28T), triple (40-30-22T).
CS-M9000 Cassette: One for Everyone
XTR has just one 11-speed cassette, a 11-40t version that uses alloy, steel, titanium and carbon.
Rhythm is the essence of smooth power transfer and proper gear step is the key to maintaining rhythm over varied terrain. The XTR CS-M9000 11-speed 11-40T cassette is the widest range cassette Shimano has ever produced and also it’s most balanced. Thanks to its “rhythm step” progression, it maintains calculated, shock-free gear steps from one gear to the next, saving riders energy and helping maintain rhythm on the trail. Key features include:
* A new HG-X11 specific tooth profile.
* Carbon spider with aluminum, titanium and steel cogs.
