    I purchased this RAP thru-axle to replace a 15mm QR on an X-Fusion Sweep, non-boost spacing. The factory QR axle kept coming loose, which is never a good thing, and this is the perfect replacement for it. The non-boost version axle length is 140mm, this one is 142mm, which means 2mm protrudes on the non-drive side. The RAP axle has twice the thread count of the stock axle, so there is plenty of thread engagement to ensure your wheel is secure. The 2mm axle protrusion isn’t noticeable, and after 50 miles of riding, the axle hasn’t backed off at all. Great purchase, and I cannot recommend it enough!

    I wish the LIG 513 I bought would have fit my 2022 Como 3.0, as the 3 piece factory axle came apart when removing the wheel on the 2nd or 3rd time. Unfortunately, this model wasn’t listed in the finder, and the axle head on the closest match (the LIG 513) was too big to recess into the space designed in the fork for the axle bolt. I guess I have to keep nursing the factory bolt along and hope my reinstallation of LockTight will keep it in one piece.
    Support was helpful throughout and promptly refunded the order.

    I purchased this to replace the thru axle on my Aventon Level because I couldn’t get the OEM part anywhere. This worked great for the first couple of rides at the end of winter and I’m looking forward to many hundreds more miles on it this year.
