Having some issues finding a 54t 144bcd 3/32 chainring, for a not exorbitant price.
Try seeing if someone has an old-school Campag large chainring. The older models had 144mm PCD, full size teeth and no ramps/pegs so they work well for single chainring applications. I got a 54t chainring for free on here a while back from the very kind @PhilDAS.
I'm swapping cranks on my brompton, putting on some spare Sugino 75's.

Anyone got one, or links to where I can purchase one?
Have bike booked in for rear triangle replacement end of this week, and want to get the cranks swapped over at the same time.
thanks
