Description

Riders who like the idea of giving their tires some extra volume and support will find the ideal partner with the XM 481. Its full 30 mm of inner width together with a minimal hook and perfect tubeless compatibility make it ready to tackle all demanding trails, both up and down the mountain.
Features:
System weight:
– The system weight is composed of the weight of the rider and his equipment, plus the bike with luggage.
Rim Diameter:
– The 700c (622 mm / 29 inches) is the most common wheel size for road racing. The 650b (584 mm / 27.5 inches) wheel size is used in specific areas. Each wheel size offers unique advantages for different kinds of riding.
Rim height:
– In cycling, rim height significantly impacts the aerodynamics, agility and weight of the wheel. The general principle is the higher the profile of the rim, the greater the aerodynamic advantage the lower the profile of the rim, the greater the response and better the handling when cornering and changing speed.
Rim Inner Width:
– DT Swiss offers MTB rims with inner rim widths of 20 – 76 mm. The right combination of tire width and rim width leads to ideal tire support. Better tire support reduces the risk of ´´burping´´ and therefore allows the tire pressure to be reduced. On the other hand, wider rims and wider tires also increase the weight of the wheels.
Brake Interface:
– The advantage of the Center Lock system is that the disc brake attachment is made with one single lock ring, which facilitates assembly. On the other hand, an advantage of the IS-System (6 Bolt) is that in the event of a necessary repair on the trail, no special tool is needed for disassembly.
Welded:
– Welded refers to a method used in making rims. In this case, the profile ends of the rim are connected by welding. This precise, stable and lightweight connection is used on all high-quality aluminum rims. This manufacturing process is the most expensive due to the effort involved, but it offers the most reliable connection.
Hooked / Crotchet tubeless TC:
– Hooked or crotchet refers to the shape of the rim flange. In this variant, the rim flange has a so-called hook. This supports the fixation of the tire bead and ensures safe function, also in high pressure use cases (>5 bar tire pressure). Tubeless refers to the ability of the rim to be used without a tube, but a tube set up is also possible.
Pro Lock:
– Pro Lock is a thread lock function which prevents the spoke-nipple connection from loosening, allowing for extremely durable wheel builds.
