ENVE’s M60 rims are supplied with valves and tape, making it straightforward to get them set up tubeless. The 23mm internal rim width means you get a good tyre profile and a comfortable volume. We tested them laced to Chris King hubs.
Their deep rim section means that if you do get a flat you’ll need a spare tube with a tall valve – or one of the valve extenders that ENVE is planning to supply with the rims from now on. Our only other niggle is that you need to nip up the hub bearings after every ride until they bed in.
The price tag is staggeringly high but these stiff, light (ours weighed 1,670g) and accurate wheels really elevated the performance of our 29er test bike. Pickup from the rear hub is rapid and consistent and it doesn’t take long to spin them up to speed. It’s in steep, high load turns where they stand out though, with none of the vagueness and flex that 29er wheels can be prone to. Even pushing them hard at low tyre pressures (20psi), we had no burping issues with the hookless rim. They’ll take a proper beating too – after months of hard riding ours are still running true.
