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.

SKU: TWO207 Category:


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.

    This being the 3. axle leaves no discussion on the quality of their products. I do find the customer service second to none. Immediate response even to the extend of looking into my personal products for me.
    Thank you ever so much. I‘ll be back with more bikes

    Just attached my trailer from Amazon to my fat bike last week. It worked perfectly. Was just a bit tight getting it on, but that’s because of the trailer attachment. The info on the website to determine which one you need is excellent. Will definitely look them up for another bike.

    Excellent product!
    The team was a big help getting me the proper Axle to fit my bike.

    Problem was that the overall width is just too wide to accommodate the Surly Ted Trailer Hitch once adding on the nuts.

    Total assembled width to the outside of the bearings looked to be 255mm. Max that the hitch could accommodate is 220mm.

    Why 4 stars?
    Well, partly my bad. Surly has those specs listed.
    Fit to bike was perfect.
    Likely getting a different trailer in the future to use with this one.

    Just know that this is likely too wide for the Surly Ted/Bill hitch.
