Triban 500 SE Bottom Bracket



Looing for a bit of help, I have a Triban 500 SE and im looking to give it an overhall with like for like parts, it has taken a bit of a hammering in all weather over the last year.


I can find and source everything but the BB - its says on the description on Decathlons website that its a Shimano Octalink BB - but I have no idea what size, etc.


Anyone any ideas?

Hello, I think it was 121mm but I'm not 100% certain, best thing would be to take it out and measure the length to make sure what size it is.

Could you tell me what size BB I need to fit a prowheel ounce triple chainset to a 500SE.


I have the bike minus a crankset with an octalink BB and I have the prowheel crankset from a donor bike so need to know what square taper bottom bracket I need to fit to make it work.
