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 center to the edge of the wheels. Having a high strength-to-weight ratio, it allows us to make very lightweight oversize jockey wheels without sacrificing strength and durability, most importantly it looks cool!

2 year warranty.
