SRAM 900 Front Hub

Whether the goal is a finish line, epic adventure or simply getting back home again, our new 900 hubs are ready for
the challenge. On the inside, our smooth and durable Double Time drive mechanism ensures rapid lightning-fast
engagement for quick and confident pedal responsiveness. SpeedBall bearings provide smooth, long-lasting rotation
performance. Multiple spoke-count and cassette-capability options, as well as interchangeable end caps make the 900
hubs a perfect choice for any disc-equipped road, gravel, cyclocross, cross country, trail, or enduro bike.

Technology

Double Time

Ratcheting up the smarts. This straight-aligned, 4-pawl design turns the 26-tooth ratchet ring into 52 points of
contact. The result: smooth 6.9-degree engagement without reducing tooth size or offsetting internal geometry—which
means serious long-term durability.

Seeker

Get unbent. 3D forged and machined for lightweight strength, the flanges are angled towards the rim—allowing the
spokes to be fully in-line when tensioned. The result: reduced spoke head breakage and better overall durability.

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.

SpeedBall

The only adjustment they’ll ever need was made back at the factory. Every part of the ball bearing comes from the
exact same supplier—which means that each bearing bore can be precision machined to fit the bearing race exactly.
With tolerances this tight, the days of adjusting play after every ride are over.
SpeedBall Ceramic option available with ceramic balls for faster, smoother and longer lasting bearings.

XD Driver Body

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

Torque Caps

Torque Caps make the bond between hub and fork dropout stronger, with an increased surface area connecting the two.
This creates a stronger, stiffer interface, giving you a more responsive front wheel and more control. So you
concentrate on the most important connection, the one between your bike and the trail.
