Yoke Mount Trailer: 12mm x 162-172mm x 1.0 thread

(3 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.

    I got this axle to support my ExtraWheel trailer. I tried it out on a Specialized hardtail and with the 6mm spacer removed it should work fine on a Salsa with Boost 148 rear spacing. Thanks for the fast support. It will give us some flexibility for trying some gravel overnighters.

    I worked with that project staff to find the axle that matched my bike (Specialiazed Diverge) with my trailer (Maya Cycle). The axle was perfect. It matched both the bike and the trailer adapters from the factory. The axle itself was very high quality materials and machining. The install instructions were easy to follow and took about 15 minutes to complete. I was extremely happy with this purchase.

  3. Connie Rhoades (verified owner)

    I got this axle to attach a Quiet Kat, mountain trailer to my Specialized Levo. The service person was extremely helpful with matching me up with the correct axle. Received it in a couple of days with full instructions for switching the axle out. I would highly recommend this company and this product.
