Fly Bikes Manual CNC Springhanger Brake Kit has been given some serious refinements & improvements to create possibly the best Fly Bikes brake yet. The Manual CNC Springhanger Brake is built from a combination of forged & CNC machined 6061-T6 aluminium keeping weight down & strength high. Designed to be assembled within a few seconds without any adjustment the Springhanger comes with anti-wobble adjustment caps to eliminate brake wobble. Lastly the arms on the Manual have been built stiffer & wider to easily accomodate 2.5" wide tyres.
