(4 customer reviews)

$ 62.00

If you are the DIY type or the heavy trailer user, you might need our Yoke Mount Axle. The Yoke Mount axle has M10 x 1 threaded studs on each side for attachment of a two sided trailer. This axle is compatible with the Extrawheel trailer, Surly Bill, Surly Ted and other not-so-common trailers.

The Yoke Mount Axle does NOT work with a BOB Trailer – see our BOB Trailer Axles here. And sorry, but we do not fit the Topeak trailers.

Our Yoke Mount thru-axles are for trailers that attach at both sides of the wheel. Extrawheel and the Surly Bill or Surly Ted are trailers that would be used with our Yoke Mount Axles. This axle is NOT for a BOB Trailer – see our BOB Trailer axles – and sorry, but we do not have an axle for a Topeak trailer.

    Thanks for the incredibly quick shipping around the world. Unfortunately, the bike I got this for is 600km away and I can’t get it until this &*^%$#@!! pandemic is over!

    Worked great on my Giant brand bike with 142×12 axle. I used it to add a panier rack to my bike. Axiom makes racks that mount to the axle extensions. Axle thread was an unusual M10x1.0, but I found nuts online.

    I bought this axle for my Giant Contend SL to pull a trailer, Pro Series single wheel.
    The axle fits perfectly and easy to attach.
    Only issue is the threaded outer spindles were just, just too short. It made it very difficult to attach the trailer and secure with the M10 nut
    ( found easily enough at a specialist bolt and nut store. )
    If only the extensions were a little wider.
    I will have to think of a way to attach safely.

    Great piece of hardware. My bike didn’t come with provisions for a rack mount and this solved that.
