Hi,
I recently purchased a used Campy Record large flange track hub with different wrench size locknuts - 17mm on one side and 18mm on the other. Apart from different wrench sizes, the locknuts look pretty much identical - dark gray serrated. From some Campagnolo diagrams on the net I'm assuming one of those nuts (18mm?) is not correct. While in any case this is a very very minor "issue" (if it can be called that at all), I'd like to know whether there could be any point in those locknuts having different wrench sizes. Thanks.
