I'm not sure which Thule I have. I got it used from a friend. Mine holds 3 bikes (S.O.'s, mine, and SKnot's) but so far I've only had 2 on it.

Haven't quite figured out how to put 3 on without having them bumping and damaging each other. (instruction manual is wandering around somewhere) But I did find that with two (left the middle rack empty) it really helped to strap the front wheels to the bike frames.
