Mavic E-Deemax S 27,5 Boost Wheelsets 2025

Mavic E-Deemax S 27,5 is designed and engineered for the demands of 27.5" E-MTB

Its 30 mm inner width alloy rim includes a lot of patended technologies. PFP (Pinch Flat Protection) offer a wider contact surface at the top of sidewall to significantly reduce the risk of tire cuts and punctures, FORE technology features a fully sealed upper rim bridge that eliminates the need for rim tape, ISM machining removes material from the rims in strategic areas to minimize weight without compromising strength and Black Shield treatment protects the rims against impacts and scratches.

Mavic opted for a total of 28 straight-pull, flat, double butted, steel spokes that include Fore technology and laced per 3 with no contact

E-Deemax S 27,5 is built around the new Infinity hub that includes ID360 double ratchet system for quick engagement and acceleration.  You can purchase the wheel in either 6 bolts or either Centerlock disc mount and in one of the 3 free hub compatibilty Shimano HG9, XD or Micro Spline.
