For 2013 Shimano will offer multiple 650b mountain bike wheels at various price points and new Dyna-sys Deore XT and SLX components designed specifically for 650b and 29-inch wheels.
For 2014, Shimano introduces new Dyna-Sys compact triple cranks tailored for mountain bikers riding 29-inch and 650b bikes. The 40-30-22T combination is available in Deore XT, SLX, and new Deore 610 series groups and offers the ultimate in trail gearing for 29er and 650b wheeled bicycles. To compliment the new gearing, two new front derailleurs will be offered in the Deore XT and SLX lines, the FD-M781-A-B and the FD-M671-A-B, down swing models with a low profile design for excellent clearance.
Shimano has greatly expanded its MTB wheel offerings with two new 650b wheelsets available at the Deore XT level and in the new WH-MT35. Also new for 2014 is the WH-MT15 that is available in 26 inch and 29 inch sizes.
Deore 610 is Shimano’s new performance mountain bike group that offers trickle-down Shimano technologies like Dyna-Sys gearing, Shadow Plus clutch rear derailleurs, ICE Technologies hydraulic disc brake systems, and 2×3 chain ring mode converters. Features like an available 15mm front thru-axle, ICE Technologies rotors and black and silver color options make Deore more attractive than ever. Available in double and triple chain ring offerings, Deore 610 is a true performance mountain bike component group available at better price points.
Both the XT and SLX chains have become more efficient, more silent and most importantly, more durable thanks to a new advanced surface treatment technology.
