A Robert Axle Project Kid Trailer thru-axle built specifically for Surly's MDS axle system, so you can tow a hitch-mount child, pet or cargo trailer from your Surly. This 197mm axle is sized for 12x197mm hub spacing and is designed to fit the Surly Ice Cream Truck.

Fit & installation

The frame-side end threads into your Surly's own axle bolt, so there is no separate thread-pitch spec to match — it is purpose-built for the Surly MDS system. The hitch-side end is stainless steel, M10x1 threaded, to take the hitch supplied with your trailer (hitch not included). It installs and removes with a standard 5mm hex key.

Compatibility & fit

This axle is built for the Surly MDS system at 12x197mm and is designed for the Surly Ice Cream Truck — it will not fit other axle systems. Confirm your bike on Robert Axle Project's online Axle Finder (robertaxleproject.com) before ordering, or bring your bike to the Tune Cycles workshop and we'll check fit before installing.

Robert Axle Project warrants its axles to be free from defects in material and workmanship for the lifetime of the original purchaser's ownership, covering manufacturing faults only — not misuse, crashes, incorrect installation or normal wear and tear. For warranty support, return the product to Tune Cycles and we'll manage the claim with Robert Axle Project's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
