$ 65.00

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.

    This worked great for attaching my MAYA single wheel trailer to my mountain bike. It’s very well built with perfect machining and a great finish and will clearly preform well for as long as I’ll ever need. Had some questions regarding purpose and fitting which the RAP team responded to quickly and clearly. Also, when I discovered I wasn’t able to find the exact nuts which secure the trailer to the post, The RAP guys sent them out to me very quickly and at no charge.

    Happy with my purchase, will buy from them again.

    This axle is exactly what is shown in the picture, perfect for my European single wheel trailer on an Haibike SDURO 6.5. Perfectly happy with my purchase, thanks!
