Rated 2 out of 5 by from Opps; not workin' I purchased this thru-axle by Rocky Mounts to go with my new Rocky Mount Pitchfork rack because I have a new thru-axle bike. The material and build quality of both these pieces are fantastic. The Pitchfork is great and would work for a normal forked bike. However, the thru-axle piece just does not work as advertised. When placed on the Pitchfork and tightened, it is still loose. You can move the thru-axle piece backward and forward, no matter how tight you make the Pitchfork skewer. And, you can only tighten it so much. Too darn bad. Then, with the bike on it, the bike will move forward and backward even with the tire strap tightened. If someone has an idea of how to get this to be tight enough so my bike is not a rocking horse, let me know. They suggest adding a second tire strap that, of course is NOT included. But, I don't believe that will prevent the thru-axle from moving, making the bike on the rack unstable. Back it all goes. Thanks REI for the great service.

Rated 2 out of 5 by from Not reliable for locking your bike It "locks" your skewer by clamping down on it hard. Even with the clamp really tight, tighter than I'd like for opening and closing it, I could still unscrew the skewer. Once it was super, super tight I was personally unable to unscrew the skewer but who knows if someone stronger than me came along and tried to steal my bike. It is more convenient than a regular adapter though as you can just leave it sitting on top of your rack and through your bike in it as long as you aren't worried about locking it. It felt solid otherwise. Will keep it but will also get a locking skewer for peace of mind.

Rated 2 out of 5 by from Wrong shims inside box The concept is nice and I'm looking forward to trying it. Unfortunately the shims that shipped with the adapter are labeled as being for a 12mm axle. They're light blue instead of black, and aren't even long enough to fit on this adapter. These shims look like they belong on another product.

Rated 2 out of 5 by from Great hardware, but shims seems wrong The hardware is tough and this feels well built but the blue 12mm shims (no 15mm shims aren't included, btw) don't fit well securely or snug in the mount. Only one half of the shim set will fit with my 12mm through axle. Feels like you're setting it up wrong but the mistake is the manufacturer.

Rated 2 out of 5 by from Great product but shims are useless Seems like they have the wrong shims in the box for 15

Rated 4 out of 5 by from Good for 15 mm through axle needs a second way to lock it to rack or can be removed, I have a locking skewer already so it works great

Rated 2 out of 5 by from Be sure to check your brake rotors You really need to be careful on which base rack you mount this too. For some, I think it would work fine but for my rack it could easily bang the brake rotors into the edge of the rack.
