Other than keeping clean I love them when having to get bike up there, muck with rack, etc. As long as you can hose 'em off you're fine. I live in a condo building so can only do stuff at car wash. I end up vacuuming them off. My dealer had a beast of a time getting the electronics to take and register in ICTP but suspect that problem's gone as it generated a Topix item and was a while back. Wow factor on them is good too.
