Shimano made the bike community wait a long time before they came across Srams XX1-drive provided an answer. The Japanese component manufacturer has now presented a completely revised version XTR-Group. The Shimano XTRseries has been in the high-end sector since it was launched and the latest version can also come up with some interesting features. First and foremost is the drive. Shimano differs with the new XTR in two variants. So there is a subdivision into race- and leisure-oriented. This can be seen above all in the new crankset.
You offer that XTR-Lineup with two different cranksets. The FC-M9000 is a race-optimized crankset that features a narrow Q-factor of just 158 mm and a super-light 3D Hollow bonded-Construction of the left crank arm. This crank option is available for 1x and 2x configurations. In the FC-M9020 it's a trail-specific crankset with an extremely strong, cold-forged construction and a standard 168mm Q-factor. This crank can be equipped with one, two or three chainrings. The special single chainring of the XTR also has a so-called Retentiontechnology that is designed to effectively prevent the chain from jumping off even without the use of chain guides.
The new eleven-speed cassette CS-M9000 with 11-40 teeth is the cassette with the widest gear range that Shimano has ever brought to the market. At the same time, it is said to be the most carefully graded cassette. through the Rhythm Step-Graduation should enable precisely calculated shift steps without large, noticeable jumps or gaps, which should save power and energy and offer more driving pleasure. The new Premium XNUMX-speed chain is presented to match CN-HG900-11, the special asymmetric HG-X11 Having outer and inner tabs and by a Sil Tec-Surface coating that minimizes friction, optimizes performance and also reduces dirt adhesion.
The rear derailleur has been expanded with the option of adjusting the friction damper as desired using a screw mechanism, which should result in greater stability and lower operating forces. In addition, the rear derailleur has an even lower profile, so that it is better protected against possible external influences. The shift levers have a double-textured, non-slip surface and are equipped with all high-end technologies such as multi-release, instant release and 2-way release. Carbon was chosen as the material for the shift levers to keep the weight as low as possible. Like its counterpart on the road, the DURA-ACE, polymer-coated cables are also used in the new XTR, which significantly optimize the shifting performance and reduce the operating forces by 20%, which is a noticeable reduction.
The new XTR M9000-Brakes will be available in a race and trail configuration. According to Shimano, great progress has been made in terms of heat management. The new brakes are said to be ten percent more heat-resistant thanks to insulated pistons and insulated brake pad coatings. The brake caliper and the master cylinder are made of magnesium and, in addition to the new carbon brake lever, are intended to reduce the weight of the XTR-Reduce the brake further. The tried-and-tested Ice-Tech brake disc remains and is intended to give the system that extra amount of power.
Also the XTR-Wheels Shimano packs a shovel on it and so they showed carbon-laminated rims for the first time in the mountain bike sector. The XTRThe wheel program ranges from ultra-light and durable race wheels to robust trail wheels in 27,5 and 29 inches, all have 28 butted spokes at the front and rear and are equipped with new, light axle and bearing systems.
