I'm about to fettle my Brompton. I think I'll have the ideal gearing if I remove the 34T chainring, fit a 44 instead, and leave the 50T.
The 34T gave me gears of 22" 27" 34" 42" 54" and 66". whereas the 44T will be 28" 35" 44" 54" 69" and 85", which would work nicely for touring. For general use I'll still have the 50T for 32" 40" 50" 62" 79" and 97", which was the default range for the M6R.
I did try the 44T a while back, as a single-ring, but my most commonly used gears when unladen were 54" and 69", a double shift.
I've spent way too long thinking about this..
No you haven't, Doctor. Tinkering with Brompton gearing is one of life's little pleasures. I love to play with mine.
Do you also spray the whole pedal platform? I find doing that also helps with creaking from the shoes that SPD are famous for
SPDs creak? I thought it was my ankles and knees all this time.
Noted re patience - for the newbies, when do you stop chasing perfection? Is there a view on "good enough"
I've come to believe the perfect is the enemy of the good, at least as my heinous bodgery goes.
