Ultralight Rear

Renthal Ultralight™ rear chainwheels are manufactured to extremely tight tolerances from  7075 T6 aluminium alloy which is 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life.

Renthal's combination of a high strength base material and exceptionally hardwearing surface result in significantly increased chainwheel life over other brands.

For the best way to find the correct Renthal UltraLight Rear Chainwheel for your model, use our Fit My Bike feature.

Ultralight™ Rear Chainwheels feature Renthal's self cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components.

Ultralight Rear Chainwheels are available in 6 colours to help you personalise your setup. The available colours are Black, Blue, Red, Green, Orange and Tanium. The anodised surface finish provides an integral coating preventing corrosion. A 15 step process is carefully carried on on each chainwheel individually.
