E-Deemax 27.5 Disc BOOST E-MTB/MTB Rear Wheel SRAM XD 6-Bolt

With a modified rim profile for improved tubeless compatibility, the E-Deemax 27.5 from Mavic continues the success story of the E-Deemax 35 in 27.5-inch format. With an inner rim width of 30 mm, the solid MTB rear wheel was developed for the special requirements of e-bikes in order to consolidate the entry into Mavic’s world of E-MTB system wheels.

With the E-Deemax S models, Mavic has already earned an excellent reputation among electric mountain bike riders. More speed, more weight and more altitude metres are just a few of the reasons why robust wheels are more in demand than ever in the electric bike community – especially when, like the E-Deemax, they can handle a system weight of 180 kilos and don’t overwhelm the scales.

The E-Deemax 27.5 has adopted innovative technologies from Mavic’s S-Class, such as Pinch Flat Protection (PFP), where the support surface of the rim flanges is so large that the risk of sidecuts during punctures is significantly reduced. The Maxtal aluminium rims are welded for greater stability and have an asymmetrical triangular profile. This helps to absorb hard shocks and impacts – from merciless rock passages to hard landings and tough compressions. Thanks to the 30 mm jaw width and tubeless-ready compatibility, the E-Deemax 27.5 can also be ridden with lower tyre pressure to increase traction and control.

The modern Infinity hub platform with self-adjusting cartridge bearings optimises stiffness and power transfer, while the Instant Drive 360 freewheel ensures lightning-fast propulsion with high durability. Plus the wider hub flange spacing of the BOOST standard also contributes to the high wheel stability. In other words, you’ll be ready to go full throttle on your e-bike and make every jump without worrying about your equipment. Because that’s exactly what Mavic’s E-Deemax are made for.

Tip:
Mountain bikers riding without electrical assistance can also benefit from the additional stability and durability these wheels offer, especially if they place high demands on the material.

Top technologies:
PFP (Pinch Flat Protection) A special rim design with a wide projecting rim flange for more contact surface with the tyre. This minimises the risk of tyre failure in the event of punctures or side contact. This is particularly advantageous for E-MTBs due to the higher weight and increased drive power.
Maxtal: Light and strong – this special aluminium alloy offers a better strength-to-weight ratio than conventional 6106 alloys.
UST tubeless technology: The Mavic standard for tubeless tyres not only improves traction, comfort and rolling resistance, but also reduces the risk of tyre defects.
SUP (Soudé Usiné Process): Particularly stable, arc-welded rim joint where the weld of the rim joint is perfectly flat milled for a seamless, smooth transition to achieve balanced rotation without brake vibrations.
QRM Auto (Qualité de Roulements Mavic Auto): Smooth-running, double-sealed and maintenance-free industrial bearings with high dimensional accuracy and self-adjusting bearing preload.
ID 360 Instant Drive: A lightweight and low-friction Dual Ratchet freewheel system for explosive propulsion and reliable power transmission.
