    SUV interior rack for 12mm thru axle? help

    Looking for a way to mount my new Trek Fuel EX 7 in the cargo area of my 2008 4runner. The bike has a 142x12mm thru axle. Unfortunately this seems to be one of the least-common sizes, so the only choice I have been able to find is the RockyMounts DriveShaft series, with an extra shim to convert it from 15mm to 12mm.

    DriveShaft HM- bike racks, truck racks, car racks, thru-axle bike racks, thru-axle bike carriers, thru-axle bike mounts, thru-axle adapters
    12mm Shims

    They are rather proud of their product at $75 for the HM and $90 for the SD. A little frustrating since mounts for other sizes can be had for around $30. Feeling a bit shafted (no pun intended).

    Are there any other products that would work with a 12mm thru axle?

    142x12 is the rear axle. Are you planing to remove the rear wheel and mount it on the rack? Normally people remove the front wheel and mount it on a rack. Forks comes in 9mm QR, 15mm thru, and 20 mm thru. And of course lets not forget Boost.

    The bottom ones are for fat bike forks.

    Like others pointed out, 142 is your rear axle. That one in the above image, labeled "15mm" is the one you want.
    Oh noes. I'm going to drink the Kool-Aid.

    Right -- The OP really needs the top middle one -- correct?

    So the rear is 12 and the front is 15?
    I don't have it near me at the moment but this would seem odd to me.

    Yes sir. Take them out and compare them. Front is fatter but shorter. Rear is longer but skinnier.

    I'm actually hoping to mount my bike by the rear axle. The reason is because I want to hang it in my van vertically, with the handlebar turned 90 degrees (handlebar parallel to toptube, so it takes up less space).

    I actually bought some 15mm fork mounts with this in mind. I was holding the bike up, mocking out how it would fit, so I could decide where to place the fork mount. I realized that with the handlebars turned this way, there would actually be a shit ton of forces applied to the head tube. Normally, when the handlebars face forward, the bike can pivot relative to the fork mount. But when the fork mount is rotated 90 degrees, there is no "swivel", so any bouncing around would apply forces directly to the head tube / headset / steer tube.

    Anyhow, long-winded way of saying there may actually be an application for this. Glad Rocky Mounts is making this, but I agree--its pretty expensive!

    OP - Did you figure this out? I have a 2006 4Runner and after a few measurements I was able to get my bike and the wifes in the back via forkmount (thru -axle)

    A few key takeways:
    - seat height, mine fits but just barely (Im 5'7). The wifes bike fits fine. I actually had to remove the weird tray that the 4runners have (its easy, only two bolts.)
    - handlebar width this is a real pain. I almost had to mount my bike in the center to accommodate the 780mm bars.
    - Mount one on the left side first, that way you can still fold up the 60% side of the back seat if needed.

    I used a 1x10 pine board cut to size then wrapped it in rubber flooring you can buy by the foot at Home Depot and glued it down with construction adhesive. you can just use a board, but I wanted something to look a little more refined.

    EDIT: I am using the 15mm thru axle from KUAT.

    Picture is worth 1000 words...
