Hello!

So I bought a Colnago Primavera frame which had originally run a Campy set up and then bought an Ultegra 6500 groupset which I thought would fit as other Primavera's run it but have found that it doesn't - will I have to use a Campy set up?

Thanks for your help!

    Which bit doesn't fit? Have you fitted the Ultegra bottom bracket cups?

    ...should fit fine - it might have an Italian threaded BB (as keef suggests) but everything else is standard. Oh and the freehub is probably different.

    Well I have only tried fitting the brakes and the bottom bracket - the rear brake is fine, but the thread isn't long enough on the front brake - also the bottom bracket doesn't fit so, as you suggest, I think that I have an Englsh thread but need an Italian for the Colnago. Can I get a bottom bracket which will fit the bike but which I can also use with the crankset?

    BB should be no problem, just needs an Italian Thread, Probably cost you more for the privilege though...

    Front brake I ve no idea about , sorry...

    Longer brake nut for the calipers - this is an issue of the fork fitment requiring it as opposed to a Shimano./Campag thing. Bikeshops will stock a variety of these of look online.

    Great! Thanks for the help guys! I will pop to my LBS today and see about the longer brake nut rather than ordering online as I'm not sure what size I will need.

    As for the bottom bracket, here is a picture of the one I currently have - Bottom_Bracket.jpg

    Now the 70 means it is English thread - 68 is Italian... Right? So this is only dependent upon the frame and not the crankset.

    The other variable, as far as I can work out is the 109.5. It seems that 105 (5500) and Ultegra (6500) come in two sizes - 109.5 and 118. so my question is - is this variable dependent at all upon the frame or is it only dependent upon the crankset (or both). In other words, if the original was 109.5, I should replace it with another 109.5 and it doesn't matter which frame it is mounted on...

    Thank you for all your help again!!

    Sorry that message is convoluted! In short - I want a BB-5500 or BB-6500, 68x109.5.... right?

    Jeeze Louise!

    Weell, you can see that the width is the 109.5 value as it's printed on the label so ideally you want one of them, for Octalink, Italian thread.
    Maybe this is what you need - out of stock at CRC

    this here - not the cheapest for 105 though :

    70 is Italian and 68 is English, yes.

    109.5 is for doubles/compacts, 118 is for triples

    Thanks guys! Your help has been invaluable! I bought the longer nut for the brake calipers and that fitted great, I will now order the correct bottom bracket and then get building!
