    I was trying to average around 50km/h on a 3km stretch, and have found I can average a higher speed on my winter bike compared to the summer one. It's also noticable downhill, even more so I guess. I realise 50km/h is achievable on a 50/12 but of course this is only an average, and on some slight downhill sections might hit 60km/h. Thanks for the link, that's a useful website.

    OK, 'need' then :) It's a compact chainset so 50/11 is currently my highest gear and I find I'm spinning out on the flat sometimes compared to my winter bike which has 50/12.

    .....ummmmm....won't this make you 'spin out' even more? Think about it... :lol:

    Oh yes, just noticed I had this the wrong way round. I have 50/12 and 'need' to go to a 50/11 :D

    Watch Brian Moore on you tube. My b limit screw was way off. Also fine tuned h/l limit screws like he shows. Sounds good on stand will ride tomorrow.

    had something similar wrt skipping when changing up the block, also difficult to shift to the biggest sprocket. works out the B screw was Jammed in too far and after slackening that off very slightly it worked a lot better.

    never had that happen before...

    Have the same thing and think it is just down to the design of the cassette. Watching how the chain links mesh over the top there are a couple of sections with more pronounced teeth and these seem to make a bit of noise when the chain rolls over.
