Build

The 25mm internal rim width suits large-volume gravel and road tyres, and the off-centre spoke drilling evens out spoke tension either side of the disc offset for a wheel that holds true for longer. A 4-pawl engagement system is built into the freehub body for reliable pick-up with minimal servicing.

Note: avoid ammonia-based tubeless sealants on this rim – Ritchey warns they can damage the rim finish.

Compatibility & fit

Shimano HG freehub, for 9–11-speed and 12-speed Shimano road cassettes. Thru-axle only (100x12mm front, 142x12mm rear) – not interchangeable with quick-release frames or forks. 6-Bolt rotors only. The Tune workshop can true, tension-check or fit tyres to this wheelset as part of a service.

Ritchey covers this product for two years from the date of purchase against defects in materials and workmanship (the Ritchey International warranty, which covers Australia). Ritchey lists rims and hubs as wear items, so normal wear isn't covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with Ritchey's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
