DT Swiss FR 541 27.5´´ 30 DB VI Disc Tubeless MTB Rim 27.5´´ 28H Black / Red

The FR 541 may not be your first rim, but it aspires to be the last. The new rim shape improves the impact resistance, enabling you to push a little harder on the trails. It also enhances the pinch flat protection for a trusty ride on rougher tracks. Build this rim with care and it will reward you with resistance and lightness for a long-lasting bond.

Features:

System weight:
– The system weight is composed of the weight of the rider and his equipment, plus the bike with luggage.

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.

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.

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 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.

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.

Pro Lock:
– Pro Lock is a thread lock function which prevents the spoke-nipple connection from loosening, allowing for extremely durable wheel builds.

Technology:

Nipple Technology:
– The interface between spoke and nipple is highly important for the durability of a wheel. A good reason for DT Swiss to continuosly improve and fine-tune the DT Swiss nipple range in line with the different requirements of the various cycling-disciplines. All nipples are available with or without the locking system DT Pro Lock.

DT Pro Lock® Technology:
– DT Pro Lock is a process where a dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Re-truing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.
