Rear Fit Kit - Mahle Motor Bolt On, M12 x 1.25

Old Man Mountain Rear Fit Kit - Mahle Motor Bolt On, M12 x 1.25 converts compatible bikes from standard eyelet mounting to a more secure, captured axle-mount rack interface. By anchoring the rack at the rear axle instead of relying on M5 eyelet bolts loaded in shear, this kit is a smart solution for bikes with no rack eyelets, lightly built eyelets intended for fenders, or suspension designs where stable rack placement is harder to achieve.

Designed for 12 x 1.25 mm threaded axles, this rear fit kit includes the mounting hardware, protective tape, and pucks that create a solid upper attachment point using high-strength, UV-stable zip ties—an approach intended to be safe across common frame materials when installed as directed.

• Axle-mounted rack interface - creates a low, captured mounting point at the axle for improved stability versus eyelet-only setups
• Mahle motor bolt-on compatibility - built for bikes using a M12 x 1.25 threaded axle standard
• Includes complete install parts - fit kit hardware, protective tape, and pucks for a clean, secure upper mount
• High-strength, UV-stable zip-tie puck mounting - reliable upper attachment that avoids stressing small eyelet bolts
• Rack compatibility - fits Old Man Mountain Divide, Divide Fat, and Elkhorn racks
• Load rating support - increases Divide/Divide Fat system weight limit to 70 lb when used with the appropriate fit kit
