Uno Cassette Geometry / Size Chart

Bike Geometry
Rotor Uno Cassette <p>The Rotor UNO Cassette is an ultra light, super durable, and aggressively Rotor. This Spanish company has shown they know how to make light and strong and smart components. You see it in their cranks, chain rings, their power meters, and now their drivetrain.</p> <p>While this Rotor cassette is designed to work with their drivetrain, the splines on the cassette mate perfectly with SRAM- and Shimano-compatible cassette bodies. The spacing mates perfectly with SRAM, Shimano, and Campagnolo eleven-speed shifting as well. In other words, if you&rsquo;re looking for a superlight cassette, this is your baby, no matter what shifting system you&rsquo;re using.</p> <p>And it is superlight. 135g. The cogs included in this cassette, and this is the only size they currently offer, are: 11, 12, 13, 14,15, 16, 17, 19, 21, 24, 28. The 24 and 28 are machined, heat-treated and surface-treated 7075 aluminum. Those two cogs are on a splined carrier and bolted to a machined block of nine cogs, also surface-treated for low friction, that are hollow, save for the splines underneath the smallest cogs. All eleven cogs have Rotor&rsquo;s Flowdrive pattern of cuts and ramps. The cassette is secured by an aluminum lock ring that works with Shimano-compatible tools. </p> <p>Tested and ridden by the Dimension Data team at the Tour de France, the Rotor Uno Cassette is ready for your bike.</p>
