Rotor Track Spider & Axle
$ 165.00
Replacement 144mm bcd disc spider and 30mm track axle for Rotor ALDHU & VEGAST track cranks.
Can be paired with any 144mm bcd track chainring of your choice (you do not need to use a Rotor chainring).
Includes disc spider, axle & proprietary M10 chainring bolts.
Professional assembly and installation using a torque wrench and following all published torque specifications is strongly recommended.
• 144mm bcd
• length: 165mm 170mm
• chainline: 43mm
• Q-factor: 140mm
• required bottom bracket: Rotor BSA30 Track (sold separately)
• color: black
• actual weight: 233g (disc, axle & bolts)
Due to their narrow Q-factor, Rotor AHLDU and VEGAST Track cranks must be used with Rotor’s BSA30 Track bottom bracket, which has thinner external cups than all other outboard bottom brackets designed for use with a 30mm axle.
Using a bottom bracket with thicker cups may technically seem possible, but the back of the disc spider will contact the drive side cup once installed and the non-drive side cup won’t leave enough of the axle splines exposed to properly secure the left crank arm, damaging the mounting interface.
