Evolution SL R.25 28″ Disc Rearwheel
High-End aluminium disc wheelset with 25mm rim height and 120kg maximum systemweight. The Newmen Advanced SL R.25 wheel has been engineered to meet the latest tyre fitting and jump-off safety standards. Ideal for use frome road to cyclocross or even gravel grinding.
Stiff, Durable and Lightweight.: the Newmen Advanced SL R.25 Wheel Absolutely safe rim with ideal results in tire burst testing and tubeless usability with tubeless easy tires. With the experience gained from the test-winning mtb rims Newmen have been able to optimize the NEWMEN EVOLUTION SL R.25 wheelset considering optimal stiffness and weight. Their have achieved this by using the patented MG-Washer in combination with the same high-strength alloy. This results in the NEWMEN EVOLUTION SL R.25 wheelset being ideal for climbers and cyclocross-racers equally. Built around the NEWMEN straightpull hubs and 24 Sapim Laser spokes the wheelset is ready for anything: Thanks to its low rotational weight it offers fast acceleration with perfect everyday-usabiility and consistent breaking performance without any rim wear. No matter how steep the descend or how bad the weather.

One of the weak points on rims – whether aluminium or carbon – are the nipples holes in the rim. If you look at the contact surface of the nipple on the rim, it is easy to understand that these holes are a weak point. At this small supporting surface, all forces are pulled over spoke and nipple (maximum value approx. 300 kg). It is easy to imagine what will happen sooner or later: the rim will crack at precisely these points. Looking at the different solutions of the different rim and wheel manufacturers, however, one quickly realizes that there are many different approaches to solve this problem. This “problem area” didn’t let us rest on our laurels either, because all existing solutions couldn’t completely convince us. The rim profile
We had to dig deep into the box of tricks to get our rims so light and yet so stable…… but we are sure that it was worth it!
In sum, that means…. optimised rim profile without edges and corners flared rim flanges with optimized flange height and wall thickness Rim flange with above-average wall thickness Inner profile matched to our MG washer high-strength aluminium alloy with special heat treatment The optimised rim profile with no edges or corners enables us to achieve a lower wall thickness in the lateral area and, in combination with the exposed rim flanges, the shortest possible distance from the left to the right rim flange.
