Description
Offering 4-piston power at an affordable price point, the performance of the BL-MT501 Left Brake Lever and BR-MT520 Rear Caliper from Shimano is very impressive. The pistons used are two different diameters to give a more progressive feel, making control and modulation easier whilst the alloy lever features a reach adjust so its position can be personalised. The lever is also I-spec-II compatible and the whole system comes bled and with a 1,700mm hose, all ready to be fitted, although spare inserts and olive are included should any changes be necessary. Please note that adapters and rotors are not included, but it can be used with 160mm, 180mm and 203mm rotors.
