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.

Designed to keep revolving un-sprung mass to an absolute minimum and power transfer at a maximum, Renthal Ultralight™ rear chainwheels are 66% lighter than steel.

Each Ultralight™ Rear Chainwheel that leaves Renthal's engineering facilities in the UK is individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit.

High strength specially enhanced 7075 T6 aluminium alloy is used to create the perfect rear chainwheel, that is both lightweight, durable and strong.

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.
