    Hi Guys,

    I am restoring an Italian bike with the traditional bottom bracket. The BB housing is 70mm and the spindle is approximately 113mm wide. The crankset and the groupset in general is Shimano 600 (cranks are the Biopace type, but makes no difference, I assume - just bought them to replace the standard 600 that was on the bike, as the rings were on their last legs). I want to get a new BB set, an 8 speed cassette, chain and the jockey wheels. Regarding the bottom bracket - will Shimano BB-UN55 be the right choice here and will it fit if the right size is bought? I am not fully familiar with the ST BB system and there are so many systems out there so I want to make sure I get the right one.

    Another detail - the cups that cover the BB spindle bolts - can they be bought separately?

    Rear mechanism jockey wheels - where would you get a new good quality set of these?

    The headset bearings would benefit with replacement also. The set is the Campagnolo Chorus from mid or late 1990's.

    The cassette is probably the easiest part - will check websites, but if any of you have some experience, I will appreciate.

    I would really like to get this bike on the road soon. I got it stripped out to pieces and I am checking every component if needs to be replaced or just re-greased and re-assembled.

    Thank you for your offer. Unfortunately the English thread is different to Italian from what I have been researching and will not fit into an Italian frame BB housing :(.
