Sram's new 900 level hubs bring all the technology from their class-leading X0 hubs down to a lower price point.

Features:

• Double Time Engagement - 52 points of engagement via 4 pawls this equates to the freehub engaging every 6.9 degrees. Fast!
• Seeker: Very clever - the hub flanges are angled to point at the rim. This ensures the spokes are never getting extra stress put on them by rubbing on the flange.
• Side Swap: The end caps are the same on both sides. If you have both caps off - just put them back on. It doesn't matter which side.
• Speedball: Every part of the bearings in the 900 hubs are sourced from the same supplier. This ensures exceptional accuracy time and time again. You'll never have to adjust these bearings.
• Torque Cap Compatible: If you've got a torque cap compatible fork, you can change the end caps out to the oversized torque caps. This increases the interface size between hub and fork and results in a stiffer front end.
• Weight: 275g in the lightest configuration.

Different Versions available:

• XD Driver to suit XX1 Eagle, X01 Eagle, XX1, X01, X1, GX cassettes
• Standard Freehub Body to suit all 8/9/10 speed cassettes, 11-speed NX cassettes or all Shimano 11 speed options.
