Old Man Mountain

Rear Fit Kit - 174-189mm Thru-Axle, M12 x 1.0

Old Man Mountain Rear Fit Kit - 174-189mm Thru-Axle, M12 x 1.0 converts a rear rack installation from traditional eyelet mounting to a more secure, axle-mounted interface—ideal for bikes with no rack eyelets, lightly-built eyelets intended for fenders, or riders who want a lower, captured mounting point at the dropout. This fit kit replaces reliance on small M5 fasteners loaded in shear with a purpose-built thru-axle mounting solution designed for stable cargo rack support on mixed surfaces.

• Axle-mounted rack interface - Creates a low, captured mounting point at the rear axle for improved rack stability versus typical eyelet-only mounting
• Correct axle specification - Fits 174–189mm rear thru-axle lengths with M12 x 1.0 thread for proper fit and alignment
• Rack compatibility - Designed to fit Old Man Mountain Divide, Divide Fat, and Elkhorn racks
• Upper mount pucks - Includes pucks that provide a secure upper attachment point using high-strength, UV-stable zip ties
• Complete install kit - Includes the thru-axle with mounting points, required hardware, protective tape, and pucks for a clean, rack-ready setup
• Broad bike compatibility - Suitable for full suspension, gravel, and road bikes, and listed as safe for carbon, steel, titanium, and aluminum frames and forks
• Higher-capacity setup (rack-dependent) - When used with Divide/Divide Fat racks, this style of axle mounting supports the rack system’s higher load rating (up to 70 lb, where the rack model and configuration allow)
