RockShox Maxle Ultimate Rear Thru Axle: 12x148, 180mm Length, Boost Compatible

The RockShox Maxle Ultimate Rear Thru Axle is a tool-free rear axle engineered for 12x148 Boost rear hub spacing on trail and enduro mountain bikes. The axle runs a 180mm overall length with a 20mm thread length and M12x1.75 thread pitch, spanning the full range of Boost-compatible rear dropouts. An internal cam system generates high clamping force with a simple twist of the lever body, removing the need for a hex key during trailside wheel pulls. Machined from 7075 aluminum with a hard-anodized black finish, it weighs 76 grams, sitting heavier than the Stealth variant but delivering the most consistent engagement and retention of any axle in the Maxle lineup. The right choice for riders who swap wheels frequently in rough conditions and want axle security they don't have to think about.
