Does anyone know. Whats the difference between an 11 speed 105 cassette, chain and rings and an Ultegra set up?

    If you google there's loads of articles on this. And even more opinions. See: ... 5-groupset

    I have ultegra on one bike and 105 on the other. I can't honestly tell any difference at all in shifting with the latest incarnation of 105. Really I can't. 105 is less than 200g heavier so there's not even much of a weight saving. But I have ultegra on my "nice" bike just because I wanted to kit it out with nice looking stuff! (The bike is titanium and ultegra is silvery grey and kind of goes nicely with it).

    If it's for a winter bike or a commuter, I'd definitely go with 105

    All in it's 200g.

    But I think had a article comparison between the 2 and a lot of the components came out at the same weight.

    Basically as above have already said. Bling factor.
    Too many bikes according to Mrs O.
