The current DT Swiss wheels are tubeless-ready and come with mounted tubeless rim tape and corresponding valves. For conversion, you will need a tubeless-capable tire (optimal: UST) and tire sealant. You can find both at an official dealer. Our How To video will take you through step-by-step assembly.
If you have previously ridden your bike with a tube or if the tape no longer sticks properly to the rim, we recommend that you replace the rim tape as a precaution.
How to attach the tubeless rim tape:
1. Measure the inside width of the rim.
2. The tubeless rim tape should be approx. 2 mm wider than the rim and can be bought from a specialist store.
3. Apply the tubeless rim tape. Depending on the rim/tire combination, it may be helpful to apply two or three layers of tubeless rim tape to optimally seal the rim bed.

The tire should be pumped in line with the manufacturer's instructions, in order to ensure optimum rolling resistance.
Note: This can vary depending on the tire manufacturer and model. The tire pressure impacts both the ride comfortability and stability of the wheel. See our tire pressure table for an overview of maximum tire pressures depending on tire and rim width.
You can use the Spoke Calculator to work out the correct spoke length and wheel weight. If your dealer doesn't have your required spoke length in stock, use one that is 1 mm longer.
For dealers: Order spare parts via our distributors or directly via our B2B online shop. Prices and availability are shown directly on the B2B online shop.
In cycling, rim height significantly impacts the aerodynamics, maneuverability and weight of the wheel. Basically, the higher the rim, the greater the aerodynamic advantage. The lower the rim, the more agile and maneuverable the handling.
