I currently have a UN54 72/113 bottom bracket fitted to the EBB on my Catalyst. Although they work very well for a long time, the previous one having done 4 years of commuting and year round mountain biking, I'd like to switch to something lighter. I'll be looking to replace the chainset at the same time so I don't need to stay with square taper cranks. So what can I fit to my EBB while still preserving the chainline with the Rohloff.
Whatever I choose will also need to be available with 165mm cranks as I've found these very knee friendly and always prefer to spin over grinding my way up hills.
Thanks
