DT Swiss launches three discipline-specific wheels
Since wide rims have found their way into cross country, manufacturers have been challenged. DT Swiss provides the answer for its athletes with the "XRC 1200 Spline" with 25 and 30 millimeter rims. At the World Cup in Lenzerheide, Schurter and co. will be able to enjoy the new, lighter wheels over the roots.
A lightweight rim is important in order to overcome the moment of inertia with as little effort as possible. The new "XRC 1200 Spline" cross-country wheels are seven percent lighter to accelerate than their aluminum predecessors. The 29-inch wheels weigh just 1412 grams with a 25-millimetre rim and 1480 grams with a 30-millimetre rim.
Rolling resistance can account for up to 69 percent on rough terrain. This is why many racing drivers opt for wider rims, which allow for lower air pressure, resulting in lower rolling resistance on rough terrain.
But then the rims also have to withstand punctures. DT Swiss has therefore not only created a separate rim profile for cross-country use, but also for all-mountain and enduro. Each rim is not only light but also stable.
Based on the experience of the aluminum rims, the requirements for the rims were defined, but it was also compared with the best products of the competitors. For example, the EXC enduro rim should be able to absorb 18 percent more energy from impacts without breaking than competitor products.
For this rim, DT Swiss tested more than 20 different carbon layups with different materials until the desired impact resistance was achieved. The key factors for an impact-resistant rim are the arrangement of the individual carbon layers, the ideal ratio between resin and carbon fibers and a careful manufacturing process
All these factors should make the "EXC 1200 Spline" one of the most impact-resistant carbon enduro rims on the market

Lightweight wheels also in the Enduro
The weight reduction also brings advantages in other areas: Saving power on tours, saving time in enduro racing.
The "XMC 1200 Spline" all-mountain wheels are available as 29-inch and 27.5-inch wheels weighing 1529 grams and 1435 grams - very little weight for a Sunday bike tour. But you can also enjoy the power savings here, as the new carbon wheels are eight percent easier to accelerate than the aluminum versions.
Six percent less for the "EXC 1200 Spline" enduro wheels. That sounds like very little, but it is noticeable, as enduro pros Anita and Carolin Gehrig explain: "In a direct comparison, the differences are quickly noticeable, but not only when accelerating. The EXC wheels are also easier to maneuver in terrain where an active riding style is required."
At 1670 grams, the EXC wheelset is slightly heavier, but it also has to withstand more. Like the cross-country wheels in Lenzerheide, the EXC enduro wheels will have their baptism of fire in Whistler at the sixth race of the Enduro World Series.
DT Swiss offers the "EXC 1200 Spline" as a 29-inch wheelset with a 30 millimeter rim, but also in 27.5 inches with a 35 millimeter rim. The latter weighs 1659 grams

Latest and proven components
All three wheels are fitted with DT Swiss' new Spline 180 hubs with the new Ratchet EXP freehub system. The wheels are also available with an axle standard: 148 millimetre width and 12 millimetre axle at the rear and 110 millimetre width with 15 millimetre axle at the front.
The connection between hub and rim is made by flat spokes. The mix of DT-aerolite and DT-aero-comp spokes ensures the ideal balance between weight savings and stability.
The flat or blade spokes, as they are also called, have the advantage of better aerodynamics, but also higher lateral stiffness with low weight.
The spokes are bolted together with the tried and tested DT Pro-Lock aluminum nipples with Squorx head.
