Shimano Ultegra 6800 Cogs, Float, Loose?
I just made a huge leap from a hybrid to a road bike that has an Ultegra 6800 group.
I am am a bit perplexed because I went out on a check ride today and I have some serious rattling going on at the rear of the bike.
I must add that I have to ride on a lot of chip sill covered roads and when I do something is rattling like crazy!
Are the cogs on the Ultegra 11 speed cassette supposed to float a little bit or be loose?
They seem to be attached in groups of three till you get to the smallest gears but these sets "float" independently. Is this normal?
Anyway something rattles like hell and back when I am on the chip sill (rough) roads and it's a bit disconcerting when it's a brand new bike.
