Description

Is there a greater concern when roof-racking a bike than the fear of someone walking by your car and lifting your steed as you enjoy some post-ride grub? You can't always park in front of the windows. That's why they make lockable roof racks. However, until now you haven't been able to secure your thru-axle equipped mountain bike. The Rocky Mounts Drive Shaft will do this for you so you can rest easy while you're away from your car.

The Drive Shaft provides security for your bike by physically clamping the thru-axle. The system works because you can lock the Drive Shaft to your standard locking skewer on your bike mount. Then you load your bike onto the rack with the thru-axle installed in the fork. The Drive Shaft then clamps over the axle and locks down. The clamp force can be adjusted so that, once clamped and locked, the thru-axle cannot be unscrewed from the fork. This effectively locks the front end of your bike to the car.

Rocky Mounts designed the Drive Shaft to accept 20mm and 15mm thru-axles. There are plastic shims that act to reduce the inside diameter down for the smaller 15mm axle size. Without the shims, it's sized for 20mm axles. Please Note: due to the design of the clamping head and the need to accept both axle sizes, the Drive Shaft is narrower than either axle standard. When you mount your bike, you'll simply adjust your bike roughly to center and off you go.

Slick

  • Familiarity: I've put it through the wringer

I have been using this when I transport my mountain bike on top of my Subi. It is easy to install and works very well. Sure it is not quite as easy to use as a rack that does not require you to remove your wheel, however this works better than any of the other axle mount adapters I have seen or used. Simply flip it open, remove your wheel, install your axle, and slap your ride on the rack and lock it down. Once this is tensioned properly it holds your bike in place very well.

GOAT IS GOOD

  • Familiarity: I've used it several times

Been doing this bike thing for long enough that none of my bike rack mounts work with my thru axle bikes. And now that the bike industry is playing with 20mm thru axle, figured I?d get the adaptor that will do both 15 and 20mm axles. Works as advertised. All my existing bike mounts (Yakima) have a fork lock?although I now have a separate key to keep track of (the one with this adapter), I can use the Yakima fork lock to secure the adapter and the adapter lock secures the thru axle bike. Together, it should keep the pseudo honest bike thief (aka scum of the earth) at bay.

Best out there, right now

The only thing better right now, for me, would be a hitch mount rack that doesn't require taking the front wheel off, but to "cheaply" convert my current cartop rack this is the best thing going, not terribly expensive considering it comes with the lock. I just ordered a second one.

This one is a lot easier to use than the typical fork ups where you have to hold the bike just right while putting the thru axle on, with this you already have the axle in place and just set the vice/clamp.

Best one on the market, still a pain

Definitely the best thru axle rack adapter out there, and the only one that actually locks. But its still a huge pain compared to standard QR's. Kinda wish I hadn't 'upgraded' to the thru axle on my new fork.
