Shimano debuts its lightest hydraulic disc brake system overall the XTR line. In a statement Shimano explains that the company’s engineers incorporated the use of a magnesium caliper and master cylinder construction in the new XTR BR-M987. The aim was to drop weight while maintaining system stiffness and control by properly managing heat. The BR-M987 caliper is compatible with ICE Technologies disc brake pads and the BL-M987 lever is I-spec compatible.

Rotor heat reduction
New to Shimano’s rotor line-up is the 140 millimeter SM-RT99-S Ice Technology rotor with ‘Freeza’. Freeza is a sandwich construction with an aluminum radiator fin that reduces heat. According to Shimano heat is reduced by 40 degrees compared to rotors without Freeza technology.

After a year developing, fine tuning and testing in the World Cup circuit Shimano introduces lightweight full carbon tubular offset 29-inch rims for competitive XC riders. The wheels are available as a 15mm and 12mm E-thru system in the front and 12mm E-thru and quick release in the rear. Both have a center lock rotor mount system and a quick engagement free hub body for optimum traction.

Bottom bracket
The bottom bracket has been updated too. Because of a new and smaller design thread type and press-fit type bottom brackets are lighter, have a better sealing performance and provide a smoother rotation.

The chain got a new surface technology called Sil-tec. This is an advanced surface plating technology to increase performance. It recently already debuted in the Dura-Ace 9000 chain.
