I have some Brompton questions:
My gf has a old 5 speed Brompton. She does not use the full range of gears so I was planning on changing the front chainring to a smaller one and fitting a 2 speed rear wheel.
Do I have to buy a Brompton chainring, whats the BCD and is it 1/8?
Will a 2 speed wheel drop in there a or are the frame spacings different?
Cheers
