The Rim Profile

We delved deep into our bag of tricks to create wheels that are amazingly light yet incredibly strong, and we're confident that it was worth the effort!

We incorporated…
  • A completely rounded, optimised rim profile 
  • A flared design with optimised flange length and sidewall thickness
  • Above-average flange strength
  • A spoke bed designed to work perfectly with our MG Washers
  • High-strength, special heat-treated aluminium alloy

The completely rounded, optimised rim profile has allowed us to reduce the thickness of the sidewalls whilst the flared flanges keep the bed area down to an absolute minimum.

A narrower bed means less material.
Less material means less weight.

But we didn't stop there! We also optimised the cross section and wall thicknesses for each rim width.
Our intelligent design reduces the risk of rocks denting the outside of the rim and helps to prevent the rim profile from deforming under excessive loads or when riding over potholes, etc.

The flared flanges are stronger than comparable rival products and are what make our rims extremely ding-resistant in relation to their weight.

Who's idea was it? Flared flanges have been used in motocross and enduro for many years.

One last advantage: Because the flanges flare outwards at an overall angle of 25°, the tyre is less pinched at the bead and retains a rounder 'U' shape. The results? Added comfort and more cornering grip.

The (minor) downside: For technical reasons, the tolerance on the flared flanges of our NEWMEN rims is slightly higher (+/- 0.25 mm) than normal. In particular, the process of bending a rim with a 25° flared profile is substantially more complicated than with standard rims. That's why, for hand-built wheels, we recommend truing the wheel on one side only (ideally in the direction of travel) and leaving the opposite flange to 'wobble'. This wobble is nothing to worry about and does not impair the wheel function.

The MG-Washer

Spoke (or nipple) holes are a particular weak spot on all bike rims – aluminium and carbon alike. If you look at the actual contact area where the nipple meets the rim, it's easy to see why these drilled holes are so vulnerable. All of the forces transferred via the spokes and nipples (up to around 300 kg in total) press down onto this tiny area. So you can imagine what will happen sooner or later: The rim starts to crack at this exact spot. A quick glance at other rims and manufacturers reveals that there have been many attempts to solve this problem.

But we weren't completely happy with any of the existing solutions.
That's why we designed the MG Washer (patent pending).

The MG Washer is the smallest possible way of reinforcing the nipple hole. What does this actually mean? All other solutions need more material, making them heavier.

Another advantage of our MG Washer is its symmetry. The double-sided concave recess means not only can it be assembled in either direction, but the contact area between the rim is also shifted away from the nipple hole, thus relieving pressure on this spot.

Last, but not least, the MG Washer prevents the nipple from eating away at the rim and distributes wear evenly across the nipple and washer.

The MG Washer is also suitable for use on third-party rims with a flat spoke bed.
