Doing an upgrade of my 91 British Eagle. Doing a quick search here, are they standard? I'm seeing 68 x 110 mm BB-UN73.
And how upgradable are they?
Any advice great-fully accepted, thanks
This is mine
My 1991 British Eagle K1. Photo from the wrong side but anyways. 99% sure it's Reynolds 501, 21 speed Deore LX
GCNs YouTube Tech channel have inspired me to refurbish it as a 1x gravel bike. It could give it a new lease of life.
