    I bought this axle primarily for use as a replacement for my stock axle. I disliked the handle sticking out on the stock axle with no way to really manage which way it points when the axle is tightened. It had snagged on something at least once and come loose! If / when I get a trainer, the additional piece on the end will allow me to use that also. So, bonus there. I also own an axle for my BOB trailer. Works great! My bike is a Trek Fuel EX, not your normal everyday touring bike, but it works!

    I wanted to convert the 142 QR style axle on my Trek Fuel EX7 to a true thru axle but don’t like the way the handles on 12×142 thru axles stick out and point weird directions when tightened. This fit the bill perfectly. It’s of excellent quality and finish and is even lighter than my son’s Bontrager thru axle. It still sticks out about the same as a lever but is a smaller profile and doesn’t have the lever part of course. Highly recommend this as opposed to the other limited axle options for Trek ABP bikes.

    Well designed and very well made. Installation was a cinch and the company was a pleasure to deal with! Thanks!

    I bought this axle for my Trek Superfly FS 9.8 SL mountain bike that is mounted to Tacx Smart Flow trainer. The original Trek Superfly axle is not long enough to use in my trainer. However, I needed to do some tuning for the trainer to get 192 mm axle to fit. I am very satisfied the axle. I also very grateful to the service and especially being personally contacted from The Rober Axle Project because their want to ensure that the 192 mm axle would not be too long for my trainer. Thanks a lot for brilliant customer service!!
