Highlights

  • 38T outer: alloy, 104 BCD, black sand anodised with CNC detail

Original-spec replacement

Prowheel builds the VORTEX-501 with an alloy outer ring and a steel inner ring. Replacing a worn ring with the matching size and material keeps the crankset as Prowheel specified it.

Compatibility & fit

Made for the Prowheel VORTEX-501 crankset, which takes a 104 BCD outer ring and a 64 BCD inner ring. The 38T fits the outer position and the 24T fits the inner. Replace the chain at the same time if it is worn. Fitting is a separate workshop service and isn't included. Our Marrickville workshop can swap chainrings and check chain length and chainline.
