Thanks for the back handed blessing Matt B. I respect your opinion because you are the sensei but just because you are the sensei doesn't mean you are always correct. The cross bars DO fill with water from during a good windy ride and from when you have flipped. NO the water doesn't run IMMEDIATELY out. It seeps in and it seeps out. The foam adds less than 4 lbs to the cross bars and allows no water. I like it so I do it. Total cost - $14. total weight on the 27 =8 lbs.
However in what you said there is genius: how's this for an idea: drill drainage holes in the cross bars. Water may get in but it won't stay - it will right out and you're not adding any weight. Could this be done without compromising the structural integrity of the cross bar? I'm thinking yes.
Now, anyone know how to remove the foam?
