    The ENVE M735E rim and Chris King ISO hub wheelset is the perfect complement to an electric assist mtb.

    E-mtbs are expanding riding into new areas and demographics. These wheels are for riders who choose electrical shift over lifts and shuttles but want the same performance standards when it is time to go downhill.

    The M735E features ENVE's patent-pending Protective Rim Strip. The custom rim strip is moulded in-house by ENVE and works alongside the rim's full carbon construction to absorb impact energy – protecting the tyre and rim against the large impacts e-mtbs experience and pinch flats.

    The strip also means no tape is required and that the air chamber is completely sealed, maintaining air pressure even if the rim gets damaged in the heat of racing, so you'll be able to finish your stage.

    As with all ENVE's rims, the M735E is handmade at ENVE HQ in Utah, USA, from raw uni-directional carbon fibre. The M735E's bespoke carbon laminate construction process also utilises patented moulded spoke holes, removable bladders for weight-saving precision and a gorgeous paint-free finish to further reduce weight while maintaining strength, stiffness and allowing the beautiful handmade quality to shine through.

    This wheelset is built around Chris King ISO hubs. Precision mountain bike tools, the ISO hubs use one-piece solid axles that help suspension work better and transfer every watt to the ground. With heavy duty bearing seals and a threaded driveshell seal ring, the ISO hubs thwart mud, water and contaminants.

    The hubs use bearings that Chris King manufacture in house. The bearings are used in surgical steel races that are machined simultaneously to ensure perfect matching. Chris King hubs get better with age: as the bearing tracks burnish, they get faster. 72 points of engagement gets power to the ground faster and creates the legendary Chris King ‘buzz’. All its hubs and bearings are fully serviceable.

    Built in-house at Saddleback our wheels are fully customisable, and we are able to offer a range of different specifications and hub colours to help create a totally unique set of bespoke wheels. Please be in contact if you would like to discuss build options.
