Made in very high-end materials: an ultra-light carbon fiber and full ceramic sealed bearings.
Two Oversized aluminum wheels, which coupled with full ceramic sealed bearings decrease the chain winding angle with minimal friction.
This product is composed of a carbon cage and two 7075 aluminum pulleys (14 & 17 teeth) with full ceramic sealed bearings.
