and what is this integrated cassette chain device setup?
they now do a freehub body combined with their own cassette which saves weight compared to a standard freehub body and normal cassette, also it can run down to a 9tooth sprocket which means that single chainring up front becomes a sensible option using a 9-32 10speed cassette, also they do a chiandevice thing to replace the front mech but to keep the chain on.
saw some of it last year and it looks rather nice but i can't be arsed with 10speed etc
You have enemies? Good. That means you've stood up for something in your life.
