Fast, quiet engagement and tool-free convertibility make the SRAM 900 a dependable, no-fuss foundation for a custom disc wheelset. This 28-hole rear hub runs an XDR (27.8mm) driver body for 11 and 12-speed cassettes and ships ready for both quick-release and 12x142mm thru-axle frames.
Highlights
- Double Time 4-pawl drive: 52 points of engagement for a quick 6.9-degree pickup
- SPEEDBALL sealed cartridge bearings for smooth, long-lasting rotation
- SEEKER 3D-forged flanges angled toward the rim so spokes sit fully in-line under tension
- XDR (27.8mm) driver body for 11/12-speed cassettes
- Tool-free, interchangeable end caps
- 6-bolt disc rotor mount, J-bend spokes, 28H, black
Fast, durable engagement
The Double Time drive turns a 26-tooth ratchet ring into 52 points of contact through a straight-aligned four-pawl design, so each pedal stroke is picked up almost immediately without shrinking the ratchet teeth.
XDR driver flexibility
The XDR (27.8mm) freehub is built for 11 and 12-speed SRAM cassettes. It also accepts narrower XD cassettes when the supplied 1.8mm spacer is fitted behind them, so the hub adapts to a range of drivetrains. The 28-hole drilling is a versatile all-round choice for trail and all-road wheelsets.
Compatibility & fit
28-hole, 6-bolt disc, J-bend rear hub. Supplied with a quick-release skewer and 12x142mm thru-axle end caps, so it suits both QR and 12x142mm frames. The XDR driver accepts 11/12-speed cassettes (and XD cassettes with the included spacer). Not Boost spaced.
