The Trace series: the best aluminum mountain bike rims in their class! The Trace Trail is ideal for tough, daily use in any terrain: your favourite ride around the block or the steepest climbs and descents in a faraway country. Because the weight is significantly lower that of any other 25 mm aluminum rim, the Trace Trail can even be used as rim for cross country races! And with the low weight of a wheel set built with Trace Trail rims it is very relaible due to the very high stiffness and strength. The larger internal width of 25 mm ensures that 57 mm outer tires will fit perfectly and the traction for climbing, descending and cornering can be optimized. Because the spoke holes are drilled 3 mm off center, the wheel can be build with a more even spoke tension, which significantly benefits the strength. In addition, the holes are drilled as minimally as possible and in the direction the spoke must have. This improves the strenght of the rim and avoids deflection of the spokes at the nipples to prevent spoke breakage. Like the other rims from the trace series the Trace XC is tubeless ready.
