hubby was going to do either the piece of wood thing... or just attach the fork holders to the "floor" of the "X"... but then you are stuck with a set spot for the bikes (or with the wood... you have to unscrew it and more it to new holes if you need to move the bikes)

with the traps... the black base piece (which matches my black interior ) is attached to the floor... but the other pieces can be moved along the track if needed (i.e. they need to be moved in for the mountain bike... but can go back out for the road bikes!) we can also remove any of the pieces (i.e. when we brought brie along when i did the grand tour.... we took out the wheel holder on her side in case of an accident, god forbid, and just left the othe pieces for my bike!

it all boils down to asthetics (spelling?).... i had a brand new car! i wasn't letting hubby put a bare piece of wood in there! lol!
