I am new here and first of all would like to say hallo to All
I recently purchased a classic steel bike and now trying to bring it back to proper shape and have a few queries.
Square Tapper BB - 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 caps 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. Where to find a new set?
I though the cassette should probably the easiest part. I tried to remove it, but there must be a special tool needed, not same one as for say a 10-speed cassette. The old cassette is made by Sachs, but I need a new one. Which one should I get? Photo of the cassette below:
I would like to remove the cassette, replace it and possibly replace / adjust the bearings. There is a good bit of play on the bearings and the grease is coming out of the axle. The bike was badly maintained.
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 any advice.
