    This was exactly the thing I needed for my kid trailer to hook up with my Surly Wednesday and it works flawlessly. Not only that but customer service was also excellent!

  2. Dragan (verified owner)

    This is exactly the piece I needed for my fat tire bike to accommodate the child trailer. The axle was recommended by a tech in a bike shop. The trailer’s hitch needed to be separated away from the back wheel so that it can go into the fully horizontal position, and this axle does the job. Couldn’t be happier with the product!

  3. Doss (verified owner)

    High quality part. Fits Surly Wednesday as perfectly as stock axle. Allowed me to bolt the new style Burley hitch on easily. The non-business end of the Axle is internally threaded like your stock Surly axle and uses the stock Surly bolt. 4 stars because the description does not make this clear, and Robert now knows it should…

    Best through axel for the Surly Wednesday + Kid Trailer! Couldn’t be happier. Perfectly machined and integrated for the Wednesday. Look no further.

  5. Zane (verified owner)

    Works great on my Surly Wednesday- quick shipping too. Only small complaint is that the search feature on the site doesn’t have the Wednesday in the database from what I can tell- so ensuring that I had the right axle took a bit more digging (thank you other reviewers!) than I though it would.
