*AARN* 15-panel track chainring (silver)

Track Chainrings from AARN, the product designer from Massachusetts who designs the drop ends for Geekhouse Bikes and Icarus Frames

The all new 15-panel track chainrings are durable but still light weight like the original AARN track chainrings.

CNC machined with the cutting edge computer operation. That makes these chainrings extremely durable and each of the teeth are nice and thick.

144 PCD , they're compatible with the Sugino 75, RMC Track Cranks and other track cranks.

Designed and made in Massachusetts USA.
