As I was musing in another topic, on my 1974 Zeus track bike project, “With the wheels being new, less to worry about there. In case of a flat while riding, would wing nuts be a smarter idea than simply carrying wrenches?”, these being wheels made by Wheelmaster and sold by Velomine ( WHEELS LINK ) discussed in yet another topic… anyway, measuring both front and rear the nuts for the hubs both measure 14.83. So I presume I can use a 15mm wrench, not that’s convenient when on the road. Anyone prefer wing nuts? While the wrench flats are the same, the front axle is about 8.9mm to the outside of threads, but the rear is about 9.9mm, so I figure two different size wing nuts. Hmm, a Google search only seems to show used ones on eBay, that might make matching thread sizes iffy?
