X0
by SRAM
SRAM X0 is SRAM's top-tier MTB hub from the 2010s, with a straight-aligned four-pawl DOUBLE TIME ratchet design and SPEEDBALL bearings. The rear hub uses 26 hub-shell teeth with opposing pawl pairs to deliver 52 points of engagement (6.9 degrees) — the highest engagement in the SRAM hub line at the time. Native XD-driver rear for 10/11-speed SRAM 1x groups; 15mm thru-axle or QR front options. Now largely superseded by the SRAM 900/DUB hub generation.

- Notes
- Discontinued flagship from the early-mid 2010s — SRAM no longer lists the X0 hub on sram.com, so no current MSRP exists. Engagement (52 POE / 6.9°) confirmed by Vital MTB, NSMB, and Enduro-MTB press release. Front variant was QR/15mm, HG-driver rear variants also existed early in the life of the product.
