On special occasions, bike racks need an adapter to fit the trending thru-axle, RockyMounts DriveShaft is a 12/15mm/20mm thru axle adapter that can handle both loads and the only one on the market to securely lock up your bike. It fits standard fork mounts from RockyMounts, Yakima®, and Thule®. It's wide mouth opening creates easy loading, holds tight with adjustable cam lever, and comes with snap in nylon shims to prevent the axle from being unscrewed and gives the ability to switch from 12mm to 15mm to 20mm thru axles, just like that. Comes with RockyMounts locks and keys.
The Driveshaft is BOOST 110 compatible.
*Need new shims? 12 mm can be found right here and 15 mm can be found here.
**If you would like to match another RockyMounts key, simply ask your dealer to key alike or add your lock # (ex. E192) to the comments field at checkout and we will match it.
***If you're looking for a truck bolt on solution we recommend the DriveShaft HM, found here. If you're looking for a solution that fits inside the bed channels on some Chevy®, GMC®, Nissan®, and Toyota® truck beds, check out the DriveShaft SD

Does it lock?
Yes, it includes a lock and two matching keys.
Will it fit my fork mount?
The DriveShaft is compatible with fork mounts from all manufacturers.
Is it compatible with "Boost 110"?
Yes, it will work with Boost 110 spacing.
How can I get two keyed alike?
If you get them from a dealer, ask them to find two with the same keys (the key # is stamped on the bottom of the box). We try to ship them to our dealers so this is possible. If you order them from our website, we will do this automatically. Note: Many online dealers have remote warehouses and cannot provide this service. Please call/email them to verify they can do this.
Why can't the axle just be unscrewed when locked?
The axle is gripped by the frame and is impossible to unthread before breaking the QR handle.
Is there a weight limit?
Yes, there is a 35lb weight limit. Do not try to mount your moped.
How does it fit 12mm, 15mm, and 20mm axles?
We include one set of snap-in nylon shims that will convert the stock 20mm setting to fit 15mm axles. 12mm shims are separately, here.
