As well as a Cav-developed sprinter's handlebar switch for Di2, Shimano unveils a new CX group

Shimano previews new kit

Shimano has started to reveal some of its new products, with further embargo lifting in April and June.

Deore gets a 10 speed Dyna-Sys drive train and powerful disc brakes, new SLX disc brakes with Ice Technologies are on its way and Shimano has developed a medium range trail pedal and a new mountain bike wheel set.

Deore, by the way, is 30 years old in 2012 – does that make you feel old?

Shimano introduced a wide range of 3 X 10 mountain bike components at XTR, Deore XT and SLX level in 2010. This year Deore will be upgraded with a Dyna-Sys drivetrain as well, featuring a 42-32-24T crankset, 11-34T/36T cassette sprockets and a mountain bike specific 10-speed directional HG-X chain. 

The new Deore Servo Wave disc brake can be used with the current rotors.

SLX is updated with a Servo Wave disc brake with ‘Ice Technologies’. Shimano says these brake pads and rotors significantly reduce heat buildup in the disc brake system, which prevents fading and assures a consistently high braking performance even on long downhill stretches.

The new SM-RT67 Center Lock rotors will be available in 160, 180 and 203mm. These disc brakes feature a tool-less reach adjust and easy maintenance due to a one-way bleeding system.

Shimano is introducing a new mid-range mountain bike wheel set, WH-MT55. It features disc brake only compatible clincher rims with Center Lock rotor mount. Besides the quick release version there will be an optional 15mm E-thru front wheel as well. This wheel set has been developed with 24 straight pull spokes and it will be available with black and white rims. Weight is 1920g a set.

Shimano’s Alfine gets just two updates, a 1.5W sports hub dynamo with Center Lock disc brake rotor mount, and disc brakes upgraded with Ice Technologies. These stoppers are said to be 15 percent more powerful than the current model and they feature an ergonomic brake lever for easy control. 

Shimano introduces a new series of cyclo-cross components. CX70 series is the high end version of existing CX50, and includes a Hollowtec II crankset with a cyclo-cross specific gearing of 46-36T and cantilever brakes with cartridge brake shoe holders and adjustable toe-in brake shoes.

CX50 is updated with a 2-piece crankiest, 46-36T, available in black and silver, and cantilever brakes with increased mud clearance. 

Compatible front derailleurs will be available as well, with top pull and down pull cable routing and with clamp band or brazed on. 

Ultegra is the main gruppo under embargo but what what can be revealed right now are carbon pedals and an additional colour option. The new Ultegra carbon composite pedal weighs only 265g a pair compared to 314g a pair for the current PD-6700 pedals.

Besides the current silver version, Ultegra will be available in what’s called glossy grey.
