The rails of the rack are 130cm albeit you could cut some off if necessary, depending on your frame size (the one in my pic is a 56cm frame). having said that my 29er MTB is a bit longer than the road bike so all depends what sort of bike you have. Also the bars on the road bike overhang the front of the rails by about 15cm, but you could always drop them depending on how much room you have.
That frame comes with all manner of inserts for different axle types (QRs and variety of through axles). I put the bike on the frame outside the van and carefully lift it in.
