Lifting and carrying the bike up stairs multiple times a day aggravates tendon and joint issues in my elbow and fingers. Even steering a fully packed shopping mode Brompton tends to tire my joints out, I think particularly because the bike is unbalanced and I’m having to exert constant force to keep it stable as well as propel it. I have to improve my flexibility on and off the bike as well.
I’ve been commuting for weeks nearly every day on multiple forms of transport with many a staircase between destinations, and I’m feeling the additional strain. Dropping >1kg off the bike, which I have the parts to do minus fork and triangle, would make a big difference I think.
Are there any significant differences in the P line and A line triangle and fork geo? Im thinking of saving my elbow tendons by replacing steel with Ti, but it’s not clear what the big differences are between both designs (other than a redesigned suspension block and EZ wheel mounting point on the P line).
