Strength & Durability Maximized Rims


We apply two extra layers of carbon to the spoke hole wall. The extra carbon, laid up in different angles, increases the strength of the spoke hole by 30%.

During our tests, it resulted in a max spoke tension of 390 kgf. Usually, 390kgf is more than enough force to break the nipples of your wheels, so the increased strength in these rims could save you a rim.

For example, if you crash into something that hits your spokes, you will only break the nipples, not the rim spoke holes. After that, all you need to replace are the less expensive spokes and nipples, not an entire wheel.


Our Clincher rims also include two extra layers of carbon on each of the braking walls, since the Clincher’s braking walls are built to take both the braking force from outside and tire pressure from the inside. The additional layers strengthen the braking walls, ensuring that they’re capable of handling up to 20% more strain than the usual brakes.


Strong Durable Rim Tech Structure

You may notice that the shape of the joint between the side wall and tire bed is not straight. In our reinforced rims, that area is shaped more like a triangle. This is the strongest structure we can build for a joint, which allows us to make the Clincher extra strong and durable without adding more than a few grams of weight.


Applying An Extra Layer Of Heat Resistance Basalt Fiber On The Braking Surface

In a rim brake wheel, the braking performance and durability are the key features. These qualities are even more important than the wheel’s weight and stiffness, because the braking surface’s service life determines how long your wheel will work safely.

Most full carbon wheels use the resin or carbon fiber as a braking surface. The SDM braking surface is made with an extra layer of fine, heat resistant basalt fiber, so that you don’t brake directly on the resin and shorten your wheel’s working life.

Compared to traditional carbon fiber braking, our SDM braking technology has the following advantages:

  • The weave of basalt fiber is finer than the resin or carbon fiber, you get better braking performance than you brake directly on resin or carbon fiber.
  • Quieter braking performance.
  • Higher heat resistance than resin.
  • Gives a responsive, reliable performance in wet, slippery conditions.
  • Better all-around braking performance and service life expectancy.
