Fast, quiet engagement and tool-free convertibility make the SRAM 900 a dependable, no-fuss foundation for a custom disc wheelset. This 24-hole rear hub runs a SRAM/Shimano HG-style splined driver body for 9, 10 and 11-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
• SRAM/Shimano HG driver body for 9/10/11-speed cassettes
• Tool-free, interchangeable end caps
• 6-bolt disc rotor mount, J-bend spokes, 24H, 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.

Built true

SPEEDBALL sealed cartridge bearings spin smoothly season after season, while SEEKER forged-and-machined flanges angle the spokes toward the rim so they stay in-line under tension for a stronger, longer-lasting wheel build.
