The definition of "road cycling" now includes gravel and dirt as well as pavement. At the same time, bikes are evolving to meet the fit requirements of smaller riders. Meeting these two distinct needs was the driving force behind the Zipp 303 Firecrest 650B Tubeless Disc-brake wheelset. The smaller rim size provides room within frames and forks for larger tires that deliver increased comfort, compliance, and cornering performance. With more tire between the rim and the ground, the overall wheel diameter, including the tire, is similar to a standard 700c wheel and road tire combination. Back on the pavement, the 650B is a better-fitting wheel for smaller athletes riding compatible frames. For too long, many smaller cyclists have trained and raced on standard 700c wheels, losing out on the advantages of a proper fitting wheel such as improved handling and the elimination of front wheel-toe overlap. At the center of the 303 650B Firecrest Tubeless is a versatile and durable hubset, the German-engineered ZR1 DB. - Zipp graphics and cosmetic identity that scream speed - Versatile 45mm rim profile for increased speed and better cornering, control, and comfort - Tubeless design provides secure performance when ridden at lower tire pressures - ZR1 DB hubset is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Built with Sapim CX Sprint J-bend spokes - Center Lock rotor interface (lockring included) - Ships with 12mm end caps

Touring cyclists have known theses wheels for a decade, noting their durability, simplicity, and ease of service. They're a great choice for all-condition roads.

The all-new CXR 2 gravel WheelSystem showcases Giant's prowess in building strong, lightweight carbon wheels. Through improved carbon layup, innovative hookless technology, and a large inner rim width that allows for wider tires and lower pressures, the CXR 2 is as strong as our XCR cross-country mountain bike wheel but at a much lighter weight. - Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight - Optimized carbon layup features high-tensile strength carbon fiber placed at the most crucial structural points to provide stiff, compliant, and lightweight wheels - A 35mm all-round rim profile with a contemporary wider inner width (25mm) offers improved support for today's higher volume road and gravel tires

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 Mavic's UST Road Tubeless technology. This patented system provides seamless integration between the wheel and Mavic's new Yksion Pro UST tubeless tires that makes installation, removal and maintenance easier than ever. And 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 without risking pinch flats, and the sealant helps prevent punctures. The rims are engineered using Mavic's ISM 4D technology and now feature 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. To reinforce the front wheel for disc brakes, Mavic increased the spoke count to 24. The hub is compatible with a 12mm thru-axle, 15mm thru-axle or quick release. The rear wheel uses 24 straight-pull spokes laced to Mavic's lightweight, fast engagement Instant Drive 360 hub mechanism. Delivered in 12x142, it can be also converted to regular quick release. It’s compatible with Shimano or SRAM cassettes and can be converted to Campagnolo or SRAM XD-R.
