Ex Demo Fast Fat Boy DMX960s

The satin black on matt black graphics are bit worn around the edges on this used pair of wheels, but they're in excellent structural condition, super stiff and pretty damn quick.  Built for powerful and/or heavyweight riders.  

Black hubs, black CX Rays, Shimano or Campag 11 your choice.  One pair only. Images shown are not of these particular wheels.

Fat Boy Rim with added Dark Energy

Just in: 220 Triathlon Magazine's review of the DMX960s as part of Issue 309's Big Group Test for Race Wheels

If you need to ride really fast, like Catherine Jameson did to win the 2015 Zurich 5150 and take the 2016 British middle distance triathlon crown, then this Dark Energy wheelset is just what the Spin Doctor ordered!


The new Dark Energy DMX960 wheels deliver effortless speed thanks to the differential geometry curved spacetime profiling we’ve developed for each rim.

More Grip. More Speed. Thanks to the Spin Fat Boy Rim Physics.

Front and rear aren’t just different depths. Each rim employs position-specific foil profiles to shape and form the airflow depending on its position on, in and around bike and rider. The front rim is optimised for superior leading edge performance, setting up airflow as it enters the bike’s core. At the rear we’ve concentrated on trailing edge dynamics to tame the turbulence generated as airflow exits the bike. Massive speed and cross-wind stability are thus assured.

Both front and rear full carbon Fat Boy Rims run 25mm wide at the brake tracks generating a MotoGP style arced tyre profile guaranteeing super low rolling resistance on the straights with sure-footed turn-in and huge mid-corner grip.

Here at the Speed Shop, every wheel is precision hand built to ensure that the extremely high spoke tensions we demand are fully stress relieved and evenly balanced around the rim. The result is strong, durable wheels with the immense lateral stiffness required to elevate steering precision & power transfer to unprecedented high levels.

Dark Energy DMX960s roll on our superlight forged & machined SPN alloy hubset. With 48-point HyperDrive engineering maximum power is always on tap and instantly available. You’ll find zero lag, slop or slack in this drivetrain.

And for wheels this quick, only the toughest Dark Matter ceramic hybrid braking surface and finest Belgian aero bladed Sapim CX Ray spokes will do. 11-speed ready. Average weight 1755g /pair.
