The DT Swiss XRC 300 Carbon Rim weighs about the same as a 9-speed chain and is lighter than most top-of-the-line-helmets. It's also 50-100 grams lighter than most rims we "thought" were super cool and super light. It's designed for cross-country racing where its lightweight and snappy acceleration could very well be the difference between winning and losing. Provided you don’t sacrifice durability, stiffness or strength, rotational weight is the place to save weight for maximum performance benefit.

Even though the XCR 300 rim ventures deeply into road rim weight territory, it's built specifically for the rigors of mountain bike racing. It's made of uni-directional carbon fibers that are aligned during the molding process to combat any unwanted flex in the rim. The cross section of the XRC 300 uses a double wall shape with a significant variation -- there is a vertical bridge connecting the inner and outer walls. This bridge cuts the interior cavity of the rim into two triangles. Remember what we learned about triangles in geometry class? They are super strong and super resistant to deformation.

The result of tying the walls together and creating the three-sided cross-sectional voids is a remarkably stable rim structure that can resist both the tensional stresses from the spokes and the bump forces from impacts on the trail. It's a disc brake-only design, and the sidewalls are as short as possible to make it strong and trail-ready. Each of the spokes holes have a stainless steel insert to help spread the stress loads away from the spoke hole. These inserts also guarantee that the spoke nipples will seat properly and turn easily during the wheel building and truing process.

The DT Swiss XRC 300 Carbon Rim could be the winning ticket to your next podium finish. It has a clear coated uni-directional carbon fiber finish with red and white decals. It's 24mm wide, so it will accept tires up to 2.1" with no problem. It comes drilled for 32 spokes. Claimed weight is 300g.
