Deemax 27.5 Disc BOOST MTB Wheels SRAM XD 6 Bolt

Tested by experienced Downhill and Enduro riders on the toughest race tracks around the globe, the refined Mavic Deemax 27.5″ system wheels impress more than ever with their speed, stiffness and stability. Perfect for riders who like to push their limits while being able to fully rely on their materials.

The Maxtal aluminium rims feature a 28 mm jaw width with a triangular rim profile that helps absorb hard impacts and shocks – from rough rock passages to hard landings and heavy compressions. The Mavic Black Shield treatment not only gives the Deemax wheels their cool finish, but also protects the rims from impacts and scratches. The construction with 28 double-butted steel spokes for each wheel provides the right balance of vertical compliance and stability to cope with the stresses of aggressive gravity riding.

To ensure smooth running without any play, the hubs are equipped with strong C3 industrial bearings whose bearing play is automatically adjusted thanks to QRM Auto technology. The Instant Drive 360 freehub for SRAM XD cassettes guarantees maximum agility while providing fast engagement and excellent propulsion due to an effective, 40-tooth ratchet system. Plus the wider hub flange spacing of the BOOST standard contributes to the high wheel stability. So you can really let it rip downhill – because that’s exactly what the Mavic Deemax wheels are made for. Anything else would be a waste of time.

Top technologies:
• 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.
• Black Shield Treatment: A special rim sealant on Mavic’s MTB wheels with a double coating in a matt finish increases resistance to stone chips and scratches.
• 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 with a fast 9° engagement angle, for explosive propulsion and reliable power transmission.
