Tom H.wrote a review of DT Swiss RWS Aluminum Lever Thru Bolt on September 3, 2019
Familiarity: I've used it once or twice and have initial impressions
This is a high-quality, well made product from DT Swiss, but it didn't work on my frame. If your non-threaded axle hole is not counter-sunk, then this is not the thru axle for you. I think this is for a Syntace frame. If you look closely at the 2 product photos, one has a flat washer and the other a tapered washer which is not removable. The flat washer is probably on the front/fork version. I ordered the 12mm x 142mm for the rear of my Lynskey Cooper CX frame as part of a QR to TA conversion. The size and thread pitch are correct, but my frame is not tapered like the washer on the axle. Consequently, the threaded end of the axle doesn't extend all the way to the far edge of the frame, making the axle effectively a few millimeters too short. Even though it works, it's not ideal and needed to be returned.
