SRAM X0 Disc Brake Hub

Finally, a hub worthy of the X0 name. Built to roll over the toughest mountain terrain, the SRAM X0 Hub proves that being solid doesn't mean being sluggish.

Double Time ratchet design gives you smooth 6.9-degree engagement-all while keeping everything light and steady. Super-precise Speedball bearings mean lower resistance, faster revolutions and no more time spent readjusting play. From pawl tooth to side cap, SRAM went the extra mile on the X0 Hub - so you have less to worry about on the trail.

For 6-hole brake discs.

Features

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.

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.

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.
