    I bought a single fat wheel trailer a while ago, and I had a problem with the Thru-Axle that came with it, as it was short.
    I couldn’t find a longer one, so I used a threaded rod to use my trailer.
    I bought this Thru-Axle for Bob trailer and the Hardware Kit, which is I have been using now for just about two days.
    It looks nicer, feels better, and is more secure so that I can go for multiple days MTB camping off-road trip.
