Thru Axle M6-Connector

Description |

Transform your modern bike into a cargo-ready machine with the Ortlieb Thru Axle M6‑Connector. This innovative thru-axle replaces your existing rear axle (up to 180 mm long) and features integrated M6 threads on both ends—allowing secure attachment of racks (such as Ortlieb’s Quick-Rack L or XL) or trailer couplings, even on frames without built-in mounts.

Adjustable via included spacers, its length ranges from a tapered 165 mm to a maximum of 180 mm, making it compatible with a wide variety of bikes—from carbon gravel rigs to full-suspension mountain bikes or e-bikes. Made from German aluminum, it’s both light and durable. Available in three popular thread pitches—1.0 mm, 1.5 mm, and 1.75 mm—for seamless compatibility with most dropouts.
