this is a bloody nightmare dick
There don’t seem to be any carriers which can clamp round the down tube
thule proride no
atera giro no
the bolt through forks are qr 15 and there don’t appear to be any carriers with adaptors for these yet
I e-mailed atb sales a few months ago re this and they suggested
http://www.thuleracks.com/product.asp?dept_id=8&sku=594
which is great but it is not available in the uk. I did phone thule uk about it and they said it was a US model.
so i don’t think you’ll see many mount visions on the roofs of cars i’m afraid as there doesnt seem to be a rack that fits!!
mine goes in the boot!
I have just bought a mont blanc discovery which looks promising as discussed before here
