The Zipp 3ZERO MOTO single-wall carbon rims have been sliding around under EWS racers for a bit now, and today the brand has some updates to announce. The main updates are hidden in the rear hub, where twelve pawls create 132 points of engagement (POE) for more immediate power transfer. For reference, the Industry9 1/1 hubs have 90 POE. The new Zipp hubs are Boost-spaced, with 6-bolt and center-lock rotor mounts depending on the hub selected, and 24, 28, or 32 spoke holes front and rear.
The 30mm-wide, single-wall carbon rims are said to offer similar compliance to that of a runner’s ankle in a sharp turn, allowing more of the tire tread to contact the trail on flat corners and off-camber sections. Flexibility in the rim will also reportedly help to prevent punctures since the rim can more easily move with impacts, and this same rim movement is said to noticeably smooth rock gardens and reduce hand and arm fatigue.
Both 29″ and 27.5″ diameters are available at your local Zipp dealer for $1,800 (€18,40/£1,645), which includes a lifetime warranty. The 29″ set weighs a reported 1,965g and the 27.5″ set is down at 1875g.
