ROTOR track bike crank set
It is a 30mm axle crank.
Spain has an anecdote that Rotor, which is based in Madrid, has too good performance, and the rider who is active at the forefront torn sponsor contracts and won the title.
The high -performance crank arm created by ROTOR's unique CNC technology also accepts the power of the top athlete and the spider arm with a disk shape suppresses twist and prevents power loss.
Both the arm and the spider are removed to the limit, and are very lightweight.
Recommended not only for full -fledged truck competitions, but also for stoic people who want to fly on the street.
* The chain ring and BB are not included.
