DT SWISS X 432 29" 25 mm Rim

The DT Swiss X 432rim is a 29-inch aluminum rim designed for modern cross-country riding and sport touring. Positioned as an ideal technical solution for wheel builders or as a replacement for a damaged stock rim, it offers access to DT Swiss’s legendary reliability without breaking the bank.

Its greatest strength lies in its widened profile with an internal width of 25 mm. This geometry provides excellent volume for modern XC tires, stabilizing the sidewalls in corners to optimize grip and performance at low pressure. Designed with a precision mechanical pin joint (Pin Joint) rim connection, it guarantees excellent structural stiffness and perfect compatibility with tubeless setups.

What is the difference between this rim and a higher-end model like the XR 391? The main difference lies in the assembly method and weight. The XR series uses a welded joint (SBWT) and higher-grade aluminum, resulting in a lighter weight (about 50 g lighter). The X 432 uses apin-joint construction: it’s slightly heavier, but it offers the same modern 25 mm internal width and excellent stiffness at a significantly lower cost.

What tire widths are recommended for this rim? With its 25 mm internal width, this rim is optimized for Cross-Country and light Trail tires with widths ranging from 2.10 to 2.35. This is the ideal range for achieving the best balance between speed, tire weight, and casing deformation over obstacles.

Is it compatible with electric-assist bikes (e-MTBs)? It is certified for ASTM Category 3 with a total weight limit of 110 kg. It is therefore perfectly suited for a lightweight XC-style e-MTB. However, for a heavy e-bike or serious enduro riding, we strongly recommend opting for the reinforced rims from DT Swiss’s H (Hybrid) or E (Enduro) series.
