Technology

BOOST™

With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail and enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link. Which is why SRAM has developed an open standard with Boost compatible components for SRAM drivetrain, hubs and RockShox forks.

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.

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.

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.
