I am thinking of revamping one of my 1990's steel Look bikes using Mavic components . I am lucky enough to have a Starfish triple crankset and my question is , what size b/b cassette do l need ? The one on the bike at the moment is way too short , and the spindle is 110 mm long. Any help gratefully received 👍

Maybe Ebay isn't needed l searched on the internet and there are loads of ads for them . l just have to figure out what the thread type is . It's a French frame (Look) but l guess that doesn't necessarily mean it has french thread :wacko:

I checked and you are right, my challenge is to order one with a 121mm axel . The Shimano sealed unit l removed from the frame is a BB-UN52
68
BV 1.37 x 24
JAPAN VIA
It is clearly marked mm110 L - R
Have you any idea how l tell what the thread is .....British, French or any other ?
I see that there are 121mm axel length Shimano available but l don't want to order one without knowing the nationality of the thread ^_^.
Apologies for all my questions ( and ignorance regarding sealed units ) !

68mm shell is Uk not Italian. Sheldon brown bottom bracket crib should confirm the threads.
