Designed without limitations, the ENVE M640 Chris King hub pairing is ready to be built into the definitive 27.5 or 29er trail bike wheelset for 2.8 to 3.2" tyres.
ENVE products have been used to gain more than 80 DH World Cup wins and podiums and with the M6 series, the US brand has taken this race-winning technology and honed it for trail riding.
Wide, strong and light, the M6 series has been created for riders who demand uncompromised acceleration on the climbs backed up with class-leading control and impact absorption on descents.
The M640 features an internal rim width of 40mm – perfect for riders who favour 2.8 to 3.2" tyres and are seeking maximum traction and the plushest ride.
The M640 features ENVE's Dynamic Impact Design. With the M640, this means a V-shaped rim profile paired with the brand's patented Wide Hookless Bead design. This exclusive teardrop-shaped leading edge absorbs energy for rim protection and disperses impact force for tyre protection – reducing the chance of snakebite flats or impact damage from big hits.
The high-volume tubeless design allows you to run your chosen tyres at lower pressures for maximum traction and added compliance. All this means you go faster, with improved control and ride feel, for less effort while also unlocking the full potential of your performance trail bike.
As with all ENVE's rims, the M640 is handmade from raw uni-directional carbon fibre at ENVE HQ in Utah, USA. The bespoke construction process 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.
