Very Limited Edition 

With the NEROX25, we've produced a very limited batch of M25 metal matrix rims in reverse, machining the brake tracks before we polish the rims and send them out for their regular shot of matt black anodising brew.  

The result is a rim finish to make the New Zealand All Blacks proud.  Matt black buffed everywhere, your bike will look as mean as it rides fast.

Riding the K2 Koppenberg NEROX25s is like having a pair of Max Biaggi's MotoGP wheels slotted into your bicycle. You'll experience super fast rolling, precision sure-footed turn-in and huge mid-corner grip. This is all down to the superstiff 25mm wide Fat Boy Rim section, which allows a 23c tyre to open up and achieve the optimal tread and sidewall profile that delivers the magic combination of low rolling resistance on the straights with a greater contact area for high grip on the twisty stuff.  

Every wheel is precision hand built as standard with high and even spoke tensions for immense lateral stiffness. This ensures that our wheels are not only strong and can take a pounding, but it's also the key to transfering all your power to the road and provides the platform for secure and stable handling in all conditions.

The Koppenberg Fat Boy 25mm superwide rim section is also 25mm deep and the unique 3D2 metal matrix profile, fabricated with lightweight aerospace alloy make the rim itself immensely strong and stiff compared to lesser, traditional and superlight alloy rims. As testament to its inherent strength, we've built plenty of Koppenberg MAX25s for big, heavy and super powerful riders in the 120+kg bracket.     

The matching superlight 3D forged & CNC machined alloy hubset from SPN Precision features 48-point HyperDrive fail-safe engagement for instant power / zero lag and goes all the way up to 11. And a Sapim CX-Ray / Laser aero bladed spoke package completes the build to compete very favourably against similar spec but more expensive Zipp 30s, 101s and HED Ardennes wheelsets. 

Average 1510g / pair. Note: the black finish on the brake tracks will fade with use.
