The FR 541 is a welded aluminium rim for downhill and freeride builds where strength, sensible weight and resistance to pinch flats all matter. Its 30mm internal width supports the tyre, while the revised profile is designed to cope better with hard impacts.
DT Swiss lists black rims in 27.5-inch and 29-inch diameters with 28 or 32 holes; silver versions use 32 holes. Both colours include PHR washers. Black rims come with aluminium Pro Lock Squorx nipples and extra decals; silver rims use brass Pro Lock flat-hex nipples. Match these details to the exact rim you are building.

Rim weights and nominal ERDs are DT Swiss published figures. Confirm the measurement convention and required washers when calculating spoke length. Choose the exact size, drilling and colour before planning your wheel.
The FR 541 uses a shaped rim edge to increase the force needed to pinch a tyre during an impact. It is useful protection for a wheel that will spend its life on rough downhill tracks and repeated bike-park laps.
Spread the spoke load
PHR washers spread the nipple load over a larger area of the rim. Black rims use the aluminium Pro Lock Squorx nipples pictured here; silver rims come with brass Pro Lock flat-hex nipples. Both use the PHR washer system.
