Rotor VEGAST Track crank arms, spider & axle

$ 315.00

Much like Rotor's ALDHU crank arms, the VEGAST utilizes a special manufacturing process named the “Trinity Drilling System", where an extruded aluminum bar is intricately CNC machined with three internal holes through the length of the crank, resulting in the dual benefit of an exceptionally light, strong semi-hollow crank arm with superior stiffness.

The VEGAST Track also features a disc-style spider and 30mm proprietary axle system, offering both aerodynamics and extremely stiff power transmission.

Can be paired with any 144mm bcd track chainring of your choice (you do not need to use a Rotor chainring).

Includes arms, axle, disc spider & chainring bolts.


Rotor Track cranksets use proprietary M10 chainring bolts that thread directly into the disc spider. We sell replacement sets, but you can't use any other brand or type.

• 144mm bcd

• length: 165mm, 170mm

• chainline: 43mm

• Q-factor: 140mm

• required bottom bracket: Rotor BSA30 Track (sold separately)

• color: black

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 is technically possible, but the back of the disc spider will contact the drive side cup, and the non-drive side cup won’t leave enough of the axle splines exposed to securely install the left crank arm, damaging the mounting interface.
