    looking to get a TT bike, whenever funds allow, mainly for Duathlon, 10mile tt use.
    As ill more than likely be buying 2nd hand im looking for a bit of advice as to what size would be best. i know its a "how long is a piece of string question", but hopeing some fellow boardsies can give me a few tips/pointers as to sizing.
    my road bike has a 58.5 tt with 110mm stem, so what sort of size range would i need to look at?
    ive heard people say that tt bikes are GENERALLY one size smaller than road bikes, so i PRESUME id be looking at a 56 tt?

    cheers in advance.

    Best thing to do is get a proper fitting done to know for sure

    Im not 100% sure as its a very different position on the bike

    When i was being fitted for my tt bike, i was told that the reason behind the smaller size is the top tube is shorter which allows you get over the bars propery

    It depends on what the fitting was like I suppose. I know the guy I went to fits you on his computer bike first and then offers suggestions about what type of bike and size would you suit you and then does the bike fit when you get the bike. Your guy should be able to advise you straight off though from your last bike fit as he would have all your "vital stats" so he would be able to check them off against the bike you are looking at
