The DT Swiss FR 541 may not be your first rim, but it aspires to be your last. Designed for the most demanding freeride and downhill riding, this welded aluminum 27.5" rim with silver anodized finish combines exceptional strength, optimized lightness and reinforced protection. With its 30 mm internal width and redesigned profile inspired by the EX series, it offers ideal tire support and 17% improved impact resistance compared to the previous FR 560.

Technical summary and positioning

Successor to the legendary FR 560, the FR 541 establishes itself as DT Swiss's gravity reference. It adopts the profile of the EX 511 (acclaimed in Enduro World Cup) while adding material in strategic zones — reinforced rim hooks, increased structural resistance — while lightening the rim bed. The result? A weight of 570 g in the 32-hole version, a remarkable optimization compared to traditional DH rims, without compromising on strength. Certified ASTM 5 (extreme use), it supports up to 140 kg system weight and remains approved for e-bikes (250 W, 32 km/h).

Technical highlights

• Welded aluminum construction: Welding is the strongest assembly method in the DT Swiss portfolio, guaranteeing maximum integrity and durability under repeated impacts.
• PHR system (Pro Head Reinforcement): Increases the contact surface of the nipples on the rim and distributes localized stresses, reducing load peaks. Compatible only with Squorx PHR washers and nipples from DT Swiss.
• 17% reinforced anti-pinch protection: Testing with a leading tire manufacturer confirms a clear improvement over the FR 560. The flared profile of the rim hooks increases the tire-rim contact zone during extreme compressions.
• 30 mm internal width: Modern standard optimized for wide tires (2.4" to 2.6"), allowing lower pressures, better grip and smooth rolling on rough terrain.
• Eyeletless (PHR): High-strength forged aluminum and the PHR system eliminate the need for traditional eyelets, contributing to weight savings while preserving robustness.
• Tubeless Ready Hooked: Tubeless compatible (rim bed designed for tubeless tape) and compatible with rigid or folding bead tires, offering versatility and ease of installation.

Geometry and standards

The ETRTO diameter 584-30 confirms standard 27.5" compatibility. The ERD of 565 mm allows precise spoke calculation for any custom build. The rim height of 21 mm ensures an ideal compromise between lateral stiffness and weight, while the external width of 35 mm provides excellent tire support. The 32-hole drilling (also available in 28-hole) offers versatility and resistance for heavy riders or extreme demands. Presta valve only, for disc brake exclusively.

Silver finish and customization

The special anodized silver finish provides a distinctive and vintage aesthetic, an elegant alternative to classic black. The rim is supplied with three sets of additional stickers (black chrome gold included) to customize the appearance according to your taste. An attention to detail that reflects the DT Swiss philosophy: technical performance and personal style.

Manufacturing and origin

Designed in Switzerland (Biel) by DT Swiss engineers, the FR 541 is manufactured in Taiwan at the DT Swiss Asia facilities (Taichung), where spokes, rims and wheel assemblies are produced for the global market. Swiss quality relies on a certified global production network, guaranteeing availability and rigorous standards.

For whom, for what use?

The FR 541 27.5" is aimed at freeride, downhill and aggressive enduro riders seeking the ultimate rim — the one you never replace again. Ideal for rocky terrain, committed jumps, brutal technical sections. Suited to medium to heavy riders, it is also suitable for gravity-oriented full-suspension e-bikes. Whether you ride in full 27.5" configuration or mullet (29" front, 27.5" rear), this rim integrates perfectly into a high-end custom build with DT Swiss 350, 240 or competing hubs (Hope, Industry Nine, Chris King…).
