You don’t win by being the lightest. Or the stiffest. Or the toughest. You win by being the fastest. And that takes a wheel designed specifically for the modern mountain biker.
SRAM RAIL 50 Wheels
An alloy rim that does what other alloy rims can’t. With WIDE ANGLE rim design providing superior stability, RAIL 50 can withstand the most aggressive All-Mountain/Enduro riding while setting a new benchmark for lightweight in the category.

Stacked in your favor. This hub shell design takes straight pull spoke slots and stacks them two-by-two—distributing force perfectly around the wheel’s SOLO SPOKE design. The resulting wheel dish is wider, maximizing lateral stiffness while retaining some frontal compliance.Read More
Switching axles has never been easier. Threadless side caps can be installed and replaced by hand—no tools necessary.
SIDE SWAP SYMMETRICAL side caps refuse to take sides. The left side cap is identical to the right one. No need to figure out where each cap is going.
With SOLO SPOKE, you’re never wrong. SRAM wheel design eliminates the need for different spoke lengths—one size fits the entire wheel. This identical-length design means no longer wondering whether you have the right front/rear/drive-side/nondrive-side spoke handy.
Front + Rear + Drive-Side + Nondrive-Side = 1 Spoke
Strong in the right places. The sidewalls of SRAM rims are reinforced along the wings to withstand major impact. But the sidewalls then taper in along the center—reducing overall mass. The result is a very light rim with excellent dent resistance.Read More
No tube, no-brainer. UST TUBELESS rims feature hooked edges designed to seal with UST compatible tires. The result is improved traction and control, less inertia and fewer flats.Read More
Take corners as fast as you want. SRAM wheels have a wider rim profile without significant added mass. This profile holds tire shape better, preventing tire roll and giving you superior comfort and traction around corners.
