  1. Reinaldo Santiago (verified owner)

    Perfect and very fast service. Lighter than the factory axles and great looking. I’m a very happy customer.

  2. Chris Hitchcock (verified owner)

    Great quality, great customer service. Have a couple of different axles from Robert Axle, all are great. Would give 10 stars.

  3. Michael Lim (verified owner)

    Excellent customer service. I had ordered the wrong size and they had everything in taken care of in no time. Very well made product as well.

    It’s a beautiful thing! The head is the same diameter as the flange on the sliding dropout on my SOMA Wolverine, so it looks amazingly neat and tidy. I got excellent help over the phone in ordering the right size, since it can’t be one of the makes on the axle finder tool because there are two possible pitches. I got another axle three years ago for a different project- I needed to get rid of the quick release on my front axle to allow for a pannier to hang close- and not only did it do that, but it did it with style!

  5. Aaron M Brown

    I recently purchased one of the thru-axle bolts and the ordering process was simple and fast! The selection menu that they have was a great help and made the selection process very easy. I received the bolt very quickly and the fit was exact!!! I would HIGHLY recommend ordering this product from them.

  6. James (verified owner)

    It appears my axel is a little longer then the original one, still works but have a bit of thread sticking out
    Bike is a Dogma F12 Pinarello
