Gray Road Wheels & Components

For hilly terrain and weight-sensitive racing, climbing wheels with rim depths under 30mm are the lightest choice; models like ICAN shallow-section sets often weigh under 1400g per set. Deep-section rims over 50mm deliver aero gains on flat, fast courses while mid-depth 35–50mm wheels balance aerodynamics and climbing for mixed racing.

Match the wheel to your bike's axle type (9mm quick-release or 12mm/15mm thru-axle), common hub spacing of 100mm front and 130mm rear, and the brake interface—rim brake or disc with centerlock or six-bolt rotors. Also confirm freehub compatibility with Shimano/SRAM hubs and that your frame has clearance for the chosen rim depth.

Tubeless-ready wheels with UST certification let you run lower pressures for better traction and fewer pinch flats, especially when paired with wider rim inner widths like 19–25mm. Tubulars remain a race-oriented option, but tubeless offers a practical mix of puncture resistance and everyday usability.

Aluminum rims are a solid training choice because they handle wet braking better and tolerate everyday knocks, making them ideal for frequent use and rainy conditions. Carbon rims provide lower weight and stiffness—often under 1500g per set—for racing, but aluminum's durability and wet-weather performance make it sensible for regular riding.

Wider rim inner widths (19–25mm) support larger tires like 25–32mm, which can improve comfort and rolling resistance, while shallow rims help keep weight down for climbing. Deeper rims increase aerodynamic efficiency but can change handling and require precise frame clearance, with common rim depths ranging from about 20–80mm.
