So I've just bought a used Giant tcx slr 2 2014 and the previous owner fitted it with the "complete" r7000 105 but "forgot" to mention he left the old 10 speed cs-hg50 cassette on it so i essentially have a 10 speed 105 with a 36t cog that I'll never really use in combination with the front compact 34-50 cogs.
Is it worth buying a 11 speed 105 cassette with some smaller cogs and would they even fit? I was thinking something like a 11-30 or a 11-32 since I mostly ride on somewhat flat roads here in Zagreb
