While attempting to keep Rudolph, my CHPT3 Brompton, as standard as possible, some mods have been happening (more on that soon?). This lightweight Brompton (probably?) won’t be seen with flashy wheels, more Ti, etc, so you’ll have to look hard to see changes from original.
Having said that, today’s mod fits the bill; a subtle little weight reduction that retains the original look? (Sorry, any weight weenies will have to do their own estimations for the grams saved.)
