Bike Fork Mount Thru Axle Adapter 9mm QR 12mm 15mm Thru Axle for Roof Rack Van Track and Floor Mounting Unibody Sleeve Quick Conversion 4 in 1

Fit on my rack with the supplied T-Nuts. Fit my mountain bike's front axle with the supplied adapters. It's built well and works great!

In theory, the item meets all expectations. However, the latch holding the lever down can be easily kicked out allowing the axle holder to move left and right. I made a temporary piece to hold said latch closed. I'll see if it stays closed this trip. Otherwise, the kit has done well for me the past two adventures. Only time will tell about long term durability

These are awesome.. with the extra spacers I was able to fit my fork sturdy with the through axle pin. Very thoughtful engineering went into these.

It works great on Trek's new ThruSkew 5mm quick release which is used on the new Trek Verge

When using smaller through axle sleeve, it seems as if it is too short. Forks hard to mount because of this. The sleeve for the quick release seems fine. New bike, so the forks are good, fit is good on wheel. 🤔

I was influenced to add my two cents about this Fork Mount given several of the existing wonderful reviews, especially the very informative and thorough review from Patrick. I second all of the observations about how heavy duty the mounting base is and all components are well built with very good functional fit. The locking mechanism is indeed tricky to close or open. The seemingly unintended fact that the latch easily opens when any of the adapters are rotated within the base, becomes an unintended hinderance for me as I tighten several bikes together. As I move bikes the latch opens and no longer performs its function of keeping the adapter centered on the base. Here is where my only suggestion is directed. In the attached snip there is a red box highlighting an existing flat facet on the base barrel. I wonder if the designer’s intention could be more fully established if the flat feature continues inside the barrel and onto each of the adapter rods (shown as a green highlight box), creating a “D” lock to halt the adapter rotation. Merely a suggestion since the product is so dimensionally good and performs very well as mentioned.

It’s almost perfect. The height and construction was exactly what I was looking for in a mount, and I really love the exchangeable inserts. However, the lever to swap them out is kinda tricky to undo at times. Also, the inserts will spin out sometimes when you are trying to put/pull your thru axle. It’s a small enough problem that I’ll just deal with it but it could be improved upon in future versions.

This mount is rugged, well-machined (& anodized), and the little magnetic clasp that keeps the adapters centered is brilliant! It's pricey, but the quality of all the pieces is apparent from the moment you pull it out of the box. Like other reviewers, I wish the adapters were marked. The QR adapter is obvious, but the Thru-Axle ones aren't immediately apparent if you're trying to determine the right diameter/length combo. Nothing a silver sharpie can't fix. The attachment hardware seems to be of decent quality as well, though I usually use my own screws/bolts on anything I order from Amazon. That said, the fact that T-nuts are included is another nice touch. As I said, this is toward the pricey end of no-name fork mounts, but I'd have no hesitation buying a second one!
