So...Today some dude almost destroyed two older-model Cannondale road bikes that were on his roof rack. He passed me as I was riding home from Whole Food and turned into the driveway that leads to the store's garage. I thought "No he's not going to turn down the ramp that leads to the garage with those things on his roof."Not long after that I hear a loud bang." "I have got to see this!" I thought. Doubled back to check out the scene. He had hit the first clearance waring cylinder, which was still swinging violently, but had stopped just before the second one, which was at a level below the bottom of the saddle noses and was narrow enough to hook the saddles.
