The ultimate mountain 27.5" wheelset
Made for the versatile mountain bike generation, the ENVE M640 wheelset is uncompromising
for the cross country racer, trail rider and everyone in between. The M6 Series is designed in 2 diameters
and 3 widths to ensure your sophisticated preference for tire size and pressure is met with an uncompromising
tire to rim interface.
ENVE M640 carbon rims are engineered to the highest quality standards which offer precise control
with space for voluminous tires allowing a comfortable ride. The M640s are not only extremely light but
very stiff due to the continuous fiber strands that form the mounts for the spoke holes. The high spoke
tension and reduced weight make this wheelset perfect for the rider who wants an undeniably solid ride.
You will not only climb with better traction and acceleration, but your downhill runs will also have unparalleled
control with the combination of the ENVE M640 rims and Industry Nine Hydra hubs. Generously low in weight with
an intuitive layout, the I9 hubs reduce the need for any proprietary tools so you can service them with ease. The Hydra
is the quickest engaging pawl system on the market and its 690 points of engagement offer a scant 0.52 degrees of
possible rotation before they engage.
The 27.5" 640 version of the M6 wheelset is optimized for 100-160mm of suspension travel, and is designed for an
unparalleled tire to rim interface for 2.7 - 3.2" tires.
With the ENVE M640 I9 Hydra wheelset, you can charge down any line on the mountain with controlled precision
and massive traction, knowing an easier climb back up awaits.
