The 21.6mm internal width of the Avion R offers improved cornering and decreased rolling resistance with today’s wider road tires. The design of the Avion R rim is based on Stan’s patented Bead Socket Technology. With five patents and 16 years of development, Stan’s rim design results in easier tubeless setup, lighter rotational weight and a more secure interface between the rim and tire. Designed for the wider overall pressure range of road and gravel tires, Stan’s BST-R rim shape is reinforced for higher pressure road tubeless tires, while also being compatible with lower pressure, tubeless-ready tires, and with tubes. This versatile Avion R is compatible with 25mm and 28mm tubeless road tires specifically designated for pressures up to 115 psi (7.9 bar), while also being compatible with higher volume 32mm to 50mm wide tires at pressures below 45 psi (3.1 bar). The reinforced BST-R rim design of the Avion R wheelset also makes it compatible with standard road tubes at pressures up to 115 psi.
Tested in the most extreme gravel races in the world, the 41mm deep Avion R rim strikes a balance between aerodynamics and ride quality. While many carbon rims give a harsh ride, Stan’s Radial Impact Absorbing Carbon Technology uses a rim shape and special lay-up process to deliver a ride that’s laterally stiff, while still absorbing radial road vibrations. When combined with 25mm or 28mm tubeless tires, the Avion R Pro allows the rider to brake later into corners, climb efficiently and roll faster.
"The Avions are hands down the best carbon wheels I've ever ridden,” said Cynthia Frazier of the VeloClassic/Stan’s road team. “We get the best of both worlds with a Stan's NoTubes tubeless-ready rim and an aggressive carbon profile. We can rail corners in a high speed professional crit and tackle gnarly gravel sectors in the local road race on the Avion wheels with confidence and style.”
In addition to improved handling and decreased rolling resistance, when used with Stan’s NoTubes Sealant, the Avion R Pro wheelset also allows tubeless tires to seal punctures almost instantly for outstanding durability and ride security.
Avion R Pro wheelsets include Stan’s new Neo R Ultimate Speedsync hubs. With five-degree engagement and new bearing positions that minimize axle stress and spin more smoothly, the Neo R provides fast engagement, low drag and excellent durability. Freehubs are available to fit both Shimano and Campagnolo cassettes. Avion R Pro wheelsets are laced with Sapim CX-Ray spokes (18 front and 24 rear) and Sapim Secure Lock aluminum nipples. A set of Stan’s Avion R All Weather Blue Compound brake pads is included with each wheelset and recommended for best performance, though the wheels are also compatible with Swiss Stop Black Prince and Flash Pro Platinum brake pads. Each wheelset also includes quick-release skewers.
Ready for tubeless use right out of the box, the Avion R Pro wheelset includes Stan’s yellow rim tape (already installed) and 55mm tubeless valves.
The Avion R Pro wheelset weighs 1455 g and is available now.
