Press Release: Shimano release 2015 XTR groupset

Posted by Leif Roy on Saturday April 12 2014

Shimano have released details of the next iteration of their top of the line XTR groupset and in doing so answered the question everyone has been asking: “How will the big S respond to SRAM’s XX1 narrow wide, 11 speed groupset?” The details are below but in quick summary: surprise surprise, Shimano have also launched an 11 speed option with a chainring that features a new tooth profile designed to better retain the chain (but not a narrow wide configuration).

Shimano XTR 2015

Shimano have also continued the move towards offering both ‘Trail’ and ‘Race’ specific versions of a lot of the XTR components, ‘Trail’ focusing on options, adjustability, and durability and ‘Race’ focusing on weight and performance. Other apparent highlights from the full groupset include; a very high tech front chainring made from a composite of aluminium+carbon+titanium, wheelsets featuring carbon+aluminium laminate rims, and a new ‘side swing’front derailleur that apparently “improves front shifting by 100%”.  I guess the proof will be in the pudding. We’re looking forward to getting our hands on some of these components to put them to the test. In the meantime we’d be interested to hear your thoughts. Have Shimano stepped up to the plate in response to SRAM’s moves over the last few years?

From Shimano:

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 pedalling 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 Cranks

FC-M9000

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

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 its 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.
  • Rhythm step gear progression: 11-13-15-17-19-21-24-27-31-35-40T

CN-HG900-11

Shimano introduces its premium new 11-speed chain that delivers overall better performance for mountain bikers. The CN-HG900-11 uses a HG-X11 special asymmetric plate design and Shimano’s new SIL-TEC surface treatment. Benefits of the new chain include:

  • Overall total improved performance.
  • A quieter ride, and chain operation.
  • Better mud shedding.
  • Increased chain life.April 12, 2014 3

 

XTR SHIFTING SYSTEM: THE ULTIMATE STABILITY AND RESPONSE

Shimano systems engineering creates a new level of shifting precision in the M9000 XTR shifting system. With both lighter action and increased stability, Shimano’s M9000 XTR shifting system redefines gear change performance while introducing enhanced ergonomics. XTR M9000 debuts a bold new front derailleur design and approach for larger wheels and longer travel that delivers remarkable shifting performance.

 

Shimano XTR 2015

SL-M9000

XTR M9000 offers Shimano’s most responsive mechanical shifting and controlling shifts is easier than ever thanks to a reduction in shift effort by 20 percent. The SL-M9000 shifters feature:

  • A ball bearing construction, and slick polymer-coated shift cable for smooth activation.
  • A more ergonomic release lever that utilizes wider, dual-textured carbon shift levers.
  • An improved vivid index mechanism for more pronounced feedback.
  • XTR SL-M9000 shifters also feature and debut new I-spec II mounting for more room on bar and rotation and side adjustability.

 

Shimano XTR Front derailleur 2015

FD-M9000

Shimano’s new FD-M9000 masters front shifting for double and triple crank sets with a new, first-ever Side-Swing front derailleur design that increases shift performance by a staggering 100 percent. Designed specifically with modern trail bikes in mind, Shimano’s XTR FD-M9000 Side-Swing front derailleur provides 15mm of increased tire clearance, while new cable routing dramatically reduces shifting effort. Rider Tuned front derailleur options include:

  • New FD-M9000 (triple) and FD-M9020 (double) front derailleurs that utilize a new structure with three mount options and new cable routing: High clamp, Low clamp, D-type, E-type (without plate).
  • A conventional FD-M9025 (double) increases front shift performance by 50 percent and is available in high clamp and low clamp options.

XTR

RD-M9000

With a refined Shadow RD Plus clutch rear derailleur, a new front derailleur structure and a new XTR chain (CN-HG900-11), M9000 offers the most stable drivetrain the industry has ever seen. A new Shadow design optimizes the slant angle, lowering shift effort while improving shifting and driving stability while the derailleur is even lower profile protected further from harm’s way. The new Shadow Plus clutch has a simpler external clutch adjustment, and the derailleur has a wider range of adjustment for easier setup.

  • The XTR RD-M9000 is compatible with all XTR front chain ring variations.
  • The XTR RD-M9000 is available in GS (mid cage) and SGS (long cage) options. April 12, 2014 4

 

BRAKING SYSTEM: RIDER TUNED XTR RACE AND TRAIL BRAKES

New XTR M9000 hydraulic disc brake systems are also Rider Tuned in Race and Trail versions, as not all riders come down the same mountain at the same speed. Shimano’s legacy of leading brake design stems from its dedicated study of the components of control: heat, power and stiffness. New XTR M9000 brakes offer varying levels of heat control from an insulated piston (glass fiber phenolic) and insulated pad coating that created 10 percent more heat resistance. XTR M9000 brake levers also feature new handlebar-clearing I-spec II mounting.

XTR Brake Race

XTR M9000 Race brake system

Race-tuned power and overall lighter weight thanks to a magnesium caliper and master cylinder as well as a carbon lever blade.

XTR Brake Trail

XTR M9020 Trail brake system

Trail-tuned for power and stiffness using pre-loaded aluminium caliper and a new SERVO-WAVE lever with a powerful and stiff carbon-alloy structure. The XTR M9020 Trail brakes come standard with ICE TECHNOLOGIES radiator pads for further heat reduction.

XTR rotor

SM-RT99 rotor

With an increased surface area for heat dispersion, Shimano’s FREEZA rotor for XTR-M9000 remains the ultimate in heat control that is now available in smaller size options with a lighter weight spider. The rotor provides a 50° C reduction in heat giving riders more powerful braking and greater durability and longer pad life.

The SM-RT99 is available in 140mm, 160mm, 180mm and 203mm diameter sizes. April 12, 2014 5
