EXTRALITE QRC-3S crank incl. bearings & bearing shells | 1x | 170 mm | blue-purple
Hard to believe: an aluminum crank that is lighter than its carbon competitors. How is this possible? By using the latest CNC milling technology, the crank arms are completely hollow on the inside, and the milling machine was also used to reduce weight in many places on the outside. The result is an impressively lightweight design that can be combined with a variety of compatible chainrings for different applications thanks to the 5-hole chainring mount. The hollow axle with a diameter of 30 mm, which is firmly connected to the right-hand crank arm, significantly increases the rigidity of the entire system. Oversized bearings, which are mounted directly on the shaft, promise a long service life and easy maintenance. Matching aluminum bearing shells ensure compatibility with different frames on the market. The integrated crank puller in the left crank arm makes disassembly child's play and requires no additional special tools.
Note: The chainring shown is not included in the scope of delivery.
