See it’s what’s old is new in cycling – Valentino Zippicelli had some seriously deep wheels back in the day. Possibly made from wood or is that ceramic? Looks like a giant, flat clay bowl with a tire glued on it.
Wonder if Hed has Zippy’s photo up in their wind tunnel? Had the Zipper known more about Aero, I bet he’d have worn a finely-shaped watermelon on his head.
