*AARN* track chainring 43T (black)

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

They're beautiful work of art made of highly-selected aluminum.

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.

43T chainrings are great for having a good ratio for riding dirt with a fixie.


Designed and made in Massachusetts USA.
