eThirteen eSpec EN Race Carbon Boost wheel black 27.5'/650B Whether you're after the responsive handling and weight savings of carbon wheels, or just one of those riders who is tired of wheel failures and are ready to enjoy hand built wheel quality to ride as aggressively with confidence, e*Spec Race Carbon Wheels were made for you. E*thirteen e*spec Race wheels start with a custom carbon layup and rim profile derived from years of developing World Cup Downhill wheels that our teams can trust to achieve their championship dreams. The 27.5 options come with 35mm inner width which amplifies tire stability and retention for wider e-Bike tires (like 2.7" Zeppelin), and makes for a perfect rear wheel choice on MIxed or Mullet e-bike builds.
All e*spec wheels are handbuilt to ensure the correct spoke tension, and built with butted stainless spokes, alloy nipples and nipple washers for the ultimate in build quality and dependability. Front wheels are 28H configurations to shave weight and add compliance and responsiveness, while rear wheels are 32H for maximum strength under heavy torsional and lateral loads.To make sure these wheels are tough enough for even the most aggressive e-Bike riders and highest performance motors, e*spec Race wheels use a custom triple sealed rear hub that increases dynamic load ratings by 53%, and decreases axle deflection by 37% using oversized hub bearings and a HD steel rear axle. e*spec rear hubs still have a quick 6-degree engagement HD freehub with 3 cartridge bearings to better support the driver body loads.
Available in XD, HG, and Microspline freehub body versions, all e*spec wheels are equipped with tubeless tape and our all new Quickfill Plasma Valves, so all that's left for you to do is mount up your cassette and tires, add sealant, and hit the trails. Should anything ever go wrong, your Race Carbon rims are covered by a Lifetime Guarantee and 5 year Warranty everything else. Treat yourself to one of the single largest upgrades possible, change the characteristics of your bike and raise the level of your performance. Ride harder, better, more frequently with less maintenance and more confidence with e*thirteen espec Race Carbon Wheels. All e*spec wheels can be used on any regular non-eBike. Wheelsets can be mixed or matched for either full 27.5+, full 29, or jump on the #mulletbus.
