I was thinking about that. Like the type on mountain bikes correct? My seat tube is 1-1/4" diameter at the seatpost and my bars are 7/8". Do they make clamps with that big of an I.D.? Or perhaps with enough material to remove to fit?
I have been shopping on eBay for vintage shifter balls and can't make up my mind. There's the basic black which would be classic and would match the bike but then there are so many fun options.
