absoluteBLACK
absoluteBLACK Oval 76 BCD Chainrings are designed for Rotor REX cranksets with their original 1x spider. Lighter and more stiff than original chainrings, these provide a super smooth pedaling sensation. The specially designed narrow-wide tooth profile keeps the chain snug, allowing you to leave your chain keeper in the garage. They are crafted from CNC machined 7075 aluminum, and feature an anodized finish for exceptional durability. Ovality has been optimized for each chainring size, ranging from 10.2 - 14.4%, with timing of 110.5-116.3° after TDC (top dead center).

Great replacement cap for my Purist water bottles.
I have really enjoyed using the Range Extender. I appreciate being able to just plug it in when my bike battery is getting low and feel confident I can go another 20 miles!
Satisfied with the watch, quick shipping, pleasant price.
Amazing cycling computer. Was shipped quick and great delivery.
