Get maximum frame protection and quick loading/unloading with this upright roof-mounted bike carrier that only makes contact with your bikes wheels, never touching the frame.
Do you have a rack that uses a quick release and requires you to remove your front wheel? That rack is perfect... until you buy a bike with a through axle design that won't work with the quick release. There's no need to buy a whole new rack. Just buy a 15 or 20mm through axle adapter for your quick release rack mount. Click the link to see a list of car rack accessories including through axle adapters.
This thing is so simple and easy to use. One of my favorite roof racks.
If I needed to come up with a criticism, it would be it's a bit confusing to assemble AT FIRST. However, once I figured the first part out, it was smooth sailing. This rack attached perfectly to my OEM Mercedes cross bars. When the bike is mounted, it's solid as a rock. I wish it came standard with the locks, but you need to pay extra for the accessories. I highly recommend this Thule rack.
I purchased a Thule sidearm because it was the only thing strong enough to secure my 50 pound downhill MTB. I carried that bike on the roof to Vermont, New Hampshire and Mass all the way to New Jersey, Virginia and Florida. After 4 years of use in all kinds of weather carrying various BMX, CX and XC bikes it is still holding strong. The only downside is the initial cost. I can say that it is worth it.
I have been using the Sidearm for just over a year, and has worked great! Can throw my 29er up on top of the car after a ride and don't have to take a wheel off or anything like that. There is a little rust starting on the ratchet buckle that clips over my rear wheel, but it seems to be superficial. This thing does exactly what it is supposed to, and I would buy it again.
