these mount to a Thule roof rack. i dont know if they will work on anything else. they dont work with my bike, so i am gonna replace them with the kind that clamps to the front fork. if you have that kind i will trade or i will sell these for 100 plus shipping for the pair. let me see if i can get a pic and i will post it.
this is with the rack in the position it would clamp to the down tube.
how it sits when not in use
pic of the clamp
the piece sticking up off the tray is broken off on the other side. i still have it and will include it, but it is broken. i am using a velcro strap to hold it down on the other side and it does fine.
it fits on my steel frame specialized, but not on my aluminum frame trek.
