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.
- SIDE SWAP™
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.
- SOLO SPOKE™
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
- TAPER CORE™
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.
- UST Tubeless
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.
- WIDE ANGLE™
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.

- XD™ Driver Body
XD is a new cassette driver body design that allows the use of a 10 tooth small cog and provides an improved interface with the cassette.

“All in all we found the Rail 50’s to be a great all around wheelset. The Rail 50’s price and weight make them competitive for any consumer looking for a tough, no frills wheelset that’s in it for the long haul on any bike in the 120-160mm travel range…it’s the premium features and refinements that justify its price tag and make them a worthy, no frills investment.”
"The overall ride ruled. Whether it was the rim width or nice balanced tension or both, the wheels gobbled up nasty terrain with ease. They felt stiff and solid and we weren’t afraid of bending them out of shape with a little whip here and there. A summer’s worth of riding without need of truing really struck us as a huge bonus...While SRAM may be more known for brakes and drivetrains, one shouldn’t sleep on their wheels."
