Shimano has introduced two new product specifications for the e-bike and enduro/trail market; the new 165mm E-MTB Hollowtech crank arms, and 4-piston hydraulic disc brake calipers.
The current cranksets for Shimano STEPS come in Hollowtech and Solid 175mm and 170mm lengths, but now Shimano has introduced a pair of shorter 165mm Hollowtech crank arms to provide greater ground clearance, less chance of pedal strike, and an optimally sized crank for maintaining cadenceDeore.
The new hydraulic brake calipers are in line with Deore XT components designed for a more aggressive riding style. The brakes feature Shimano’s ICE TECHNOLOGIES heat management system through its caliper design, compatible rotors and pads.
Much like Shimano’s regular 2-piston M8000 brakes, One-Way Bleeding and reach and free stroke adjustment are possible. The difference comes now with four ceramic pistons, which offer an increase in stopping power over the regular BR-M8000 brake unit.
