700c, 27-Inch & 650c

Aksium is a great choice for everyday road riding. With a smart balance of high-quality materials and durable construction, it offers aspiring road riders the clear performance benefits of a high-quality wheelset. This Aksium Disc model includes special features aimed at the unique demands of disc brake road bikes. It uses straight-pull spokes for added stiffness and strength, and we also increased the spoke count to 24 on both front and rear wheels. With a 17mm internal width, these rims are compatible with tires up to 32mm, making them versatile, comfortable, and ideal for challenging road conditions. The disc-specific hubs feature super strong QRM bearings that provide low friction and long-term durability. Powerful, reliable disc brakes for added confidence and control - 24 spokes front and rear for optimized brake torque distribution - Disc-brake optimized rim profile - Disc-friendly spoke geometry and lacing pattern Smooth, efficient ride quality - Wider 17mm (inner width) rims allow tires up to 32mm. - High-quality QRM cartridge bearings - Straight-pull round spokes are stronger than J-bend options.

A favorite for everyday road training and racing, this versatile wheel system produces a lightweight, dynamic ride quality that now has the added benefits of our UST Road Tubeless technology. This patented system provides seamless integration between the wheel and our new Yksion Pro UST tubeless tires that makes installation, removal, and maintenance easier than ever. You get all the benefits of tubeless, including less rolling resistance and a smoother, more controlled ride quality. Without tubes, you can run lower tire pressure with no risk of pinch flats, and the sealant helps prevent punctures. The rims are engineered using our ISM 4D technology and a wider design (19mm internal/23mm external). ISM stands for Inter Spoke Milling, a unique process that trims the thickness of the rim wall between the spokes to create a rim that's lighter but still very durable. Roll faster and smoother with a reduced risk of punctures - With UST Road Tubeless, no tube means no friction, so you experience less rolling resistance and higher speeds. - UST Road Tubeless lets you ride with lower tire pressure for a smoother ride and a reduced risk of punctures. - Our patented UST system offers a perfect union between tire and wheel, so installation, removal, and maintenance are easy. Climb, accelerate, and sprint faster - 17mm internal rim width increases air volume. - ISM 4D superlight rim - Double-butted steel spokes keep the weight down for a fast and comfortable ride. Powerful, reliable disc brakes for more confidence and control - 24 spokes front and rear for optimized brake torque distribution - Front hub convertible from 12mm or 15mm thru-axle to quick release.
