i've read online people sometimes cut up tiny pieces of rubber, like pencil eraser, for the threads. others use that thin teflon plumbers tape in lieu of grease. someone else used a condom. not a used condom. and not just any new synthetic condom, but the lamb intestine ones. or is it lamb skin? no, it couldn't be the actual skin. speaking of lamb, i wonder if cyclists in scotland have ever used haggis in their threads? any scots here?
