Oversize Ceramic Titanium Jockey Wheels-11T+15T-105-12 Speed

The 11-tooth and 15-tooth titanium oversize jockey wheels bring high efficiency to the drivetrain system with extremely low-friction ceramic bearings. 

Made from titanium alloys, the jockey wheels have very high tensile strength; hence, when moving to larger-size jockey wheels, the titanium alloy wheels will remain the same strength and shape from the centre to the edge of the wheels. Having a high strength-to-weight ratio, it allows us to make very lightweight oversized jockey wheels without sacrificing strength and durability; most importantly, it looks cool!
