    The axle also attached to a Scott E-Genius 710 plus. Fits almost perfectly.
    So that the axis ends flush with the inner thread, it should only be 2-3 mm longer;
    quick shipping to Germany

    Just bought a Tern GSD, which is an amazing bike, particularly with the additional cargo capacity over a standard bike, but with three kids, we still need our Burley D’Lite sometimes. The GSD is my first bike with a through axle, and while I love how rugged and still easy to use the through axles are, hooking up the Burley was not going to happen without the Robert Axle Project. As wonderful as the Tern is, the documentation is… not as great — so the sizing chart was a life saver — I was so relieved when I could see with confidence that I was ordering the right axle. When it arrived I was impressed with how carefully machined it was, and much heavier than the stock axle (which was no lightweight to start with). Installation was a breeze, and riding the GSD while pulling the trailer is a thrilling experience. If you have a thru-axle and have or are thinking about a trailer, this is the only way to go! The only possible way they could improve it is to have a pitlock (or similar) option.

    Got this to pull a Thule Chariot double on Tern GSD s10. The fit and finish on this axel second to none. I’ve been riding fully loaded for a month and everything is as tight as the day 1. The compatibility with hexlox puts it over top. Great axel and great service.

    Bought two for Tern’s GSD S10, axles fit perfectly and the Robert’s AP customer service was tops. Great product and good support, can’t ask for more than that.

    I installed this on my Tern GSD to two a burley trailer. Instructions were very clear and install went easy. They RobertAxle replacement is much stronger than the stock axle. The Tern GSD is a very good bike and the RobertAxle is a great enhancement.
