Newmen Evolution SL X.A.25 29″ Boost Front Wheel

The Newmen SL X.A. 25 Evolution Frontwheel is perfect for trail biking as well as for XC/marathon riders who want the benefits of wide rims. The flared rim flanges offer very high dent resistance and with the NEWMEN FADE hubs the wheelset has become a lot quieter.

Minimum weight, maximum performance: the SL X.A. 25 Evolution from Newmen

At 700g (29″) the Evolution X.A.25 does not need to hide from its carbon fibre competitors. The carefully engineered mix of stiffness and comfort makes this wheelset a trusty companion along everything from XC-racing, multiple day epic rides or just your quick afterwork hometrail rip. Despite its low rim weight of 400g (29″), combined with the right tires, the wheelset even makes a good impression on the descent.

The MG-Washer
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.
