Um, there are significant weight differences between many of these, so that could be an issue to bear in mind if that’s important to you…
rear skewers on my bikes range from some SR 1980 Japanese crap (actually Sansin brand a.k.a Sunshine, but merged later) at 103.4 g (all chromed steel), Campagnolo Record from 2000 at 68.2 g, (steel with alu caps), and a nice light Joytech made in Taiwan from Alu and Ti at 40.0 g.
so, saving 110 g on a wheelset by using different skewers does make sense, and it’s so easy.
Yes, i did just go and weigh them all right now. No, i do not have a logbook of weights of all my many bike parts. My name is not ColT
