Scope Cycling rolled onto our radar on the road just about a year ago with their reasonably priced, aero tubeless carbon clinchers for disc brake road bikes. We have a set of their mid-depth R4d wheels in for a long term test now, and have been very pleased with them even getting them dirty on some cross riding.
But now Scope have gotten serious about off-road racing with the new O2 mountain wheelset. In fact with a 25mm internal width & hookless bead, they call it an unparalleled wheel option for both gravel bike and cross-country mountain bike racing.
O2 off-road carbon tubeless race wheels
Another year and a half in development after their last disc brake road wheels, the new O2 wheelset required a different way of looking at wheel design. Scope wanted to develop a proper race wheelset that would offer a better balance of weight, lateral stiffness, comfort & durability than what they saw on the market for premium gravel or mountain racing.

To hit that balanced all-around race goal, Scope worked closely with Schwalbe to develop their new 31mm external, 25mm internal rim profile with a hookless tubeless bead and a 3mm lacing offset. At just 23mm deep, the new rim claims improved compliance (hence more comfort) than commonly deeper sections, while also working towards a pretty impressive 1380g total wheelset weight that can stand up to proper XC & even XCM racing. In a first of what we expect to see more of, the rims tease a AAA certification from Schwalbe, rating them as the best sealing interface between rim & tubeless tire.
