Well, I figured since I upgraded the stock wheelset to Reynolds Solitude, I might as well replace the cassette for something lighter.
Claimed weights:
4600-- 293g (12/28T)
5700-- 250g (12/25T)
6700-- 208g (11/23T)
I guess when spec-ing the gearing more similarly, we get that 1.5g difference instead of the big spread published above?
Yep. About the only difference I can see between Ultegra and 105 10-speed cassettes other than the color is the 105 uses a steel lockring while the Ultegra uses a lighter alloy one.
