The Bomb Proof Fat Boy Rim

The review above is of the MAX25 build version of this wheelset - same rim and hub combination as the M25s, but with the upgraded Sapim CX Ray / Laser spoke package. You can see what Cycling Plus magazine think of the M25s in their review of the Sarto Dinamica below.

Slot a pair of Koppenberg M25s in your bike and prepare to unleash your inner Valentino Rossi as you experience super fast rolling, precise 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 increased 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 our wheels are not only strong and can take a pounding, but it's also the key to transferring all of 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 the fail-safe 48-point HyperDrive engagement for instant power / zero lag and naturally, goes all the way up to 11. And a Sapim Race double butted spoke package completes the build to compete very favourably against similar spec but much more expensive Zipp 30s, 101s and HED Ardennes wheelsets. 

Average 1580g / pair.
