I've checked the Transmission Database but couldn't see an answer so I'm hoping some knowledgeable soul may be able to help..... just bought these retro Chorus cranks which I believe are 9 speed and part of the deal included a Shimano B/B with Italian cups (seems wrong, JIS-v-ISO?), my frame has British threads so wanted confirmation if a standard 102mm axle is correct for this model, fingers crossed! Griff
I’m using 102mm (chorus) bb with chorus double that looks just like your cranks if that helps. British thread bb.
thanks, just needed that confirmed before I go and buy the wrong size
There are more experts on here, might be worth paging @Scilly.Suffolk as well...
102mm unless the tapers have distorted.
tapers are fine, thanks for the heads up......
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
