    Industrial strength

    Posted by Michael on May 16th 2020

    First thought pulling this mount out of the box was, man this has some weight to it. I work as a field service technician on manufacturing machines, so I can spot cheaply built crap vs something that is going to last. This product is built to an above average standard. The only plastic on this mount is the release and even that looks to be a good quality polymer plastic. The finish looks to be powder coated and nicely finished. As I said before, this mount is a little heavy, this is due to being well built and I can say this mount is going to last a lifetime. This being my first product from Rockymounts , I'm impressed. I look forward to buying more products from them.

    Amazing Mount!

    Posted by Gordon Nicholson on Apr 17th 2020

    The best thru axle mount I've ever used and I've previously tried all the other major manufacturers! Rock solid construction. We carry a 40# mountain tandem in the mount without any problem. Even when we're on some rough, pothole, unpaved roads. Very secure. We have it mounted on a 'do it yourself' rail system in the bed of a truck. Highly recommend the mount.

    Great Bike mount

    Posted by Jim on Aug 15th 2019

    This mount was the perfect solution for my new bike with thru axle. While I am not really a fan of the whole thru axle craze, this mount made it much more tolerable. I have a custom bike rack I built inside my van that used a fork mount. I was going to buy one of the thru axle to quick release adapters until I saw the Driveshaft HM mount. It is so much easier to use than the adapter. With all the other mounts and adapters I saw you basically have to hold your bike steady on the rack while you thread the axle through your fork into it. With this mount you can thread the axle into the fork, lift the bike onto the rack and just flip the top plate over and clamp it. While I have to admit that this mount is a bit pricey, it really is an elegant solution and works so effortlessly that it was worth every penny. GREAT DESIGN!!!

    The mounts work well and have stood up to the elements over the last year. Depending on the rigidity of your mounting surface there is some side to side flex in the mount, this can alleviated by stabilizing the back wheel. This only applies to using the 15 mm through axle configuration.

    Awesome!

    Great hold, no movement. Locks down on the axle and is beefy enough to keep my MTB still and safe. I love it! Couldn’t ask for a better bike rack!

    Great for what it does, not so much for QR.

    Posted by Justin on Jun 13th 2018

    Love this mount, super good product and very secure. I know this isn’t designed for QR axles, but I still wish they had a locking QR dummy axle. I have one bike with a QR and one with a thru axle, so now if I want to lock the QR, I have to buy the Lowball too. I didn’t realize this when I bought it. I ride before/after work so locking is a must. Wish I could get it all done with one mount.
