Rotor ALDHU Track Crank Axle 30 mm with 144 x 5 Track Spider Set for track cycling
The Track 30 mm crank axle from Rotor allows you to use the lightweight ALDHU 3D+ or VEGAST crank arms and a noQ chainring on the track. The Q-factor is 140 mm and is thus matched to the range of use. The axle is supplied including a 5-hole spider with 144 mm bolt circle diameter. In addition, there are five chainring bolts which, unlike the previous model, are screwed into the chainring using the threads of the Spider.
