I'm using the standard 130BCD Brompton ring, 54t I believe.
I was asking on here about Campag cranks but getting hold of 3/32 single speed rings without ramps and pins in 54t (or thereabouts) seemed difficult enough in 130 or 110 bcd, never mind 135.

What tooth chainring are you using?
I'll be picking up my S2L as soon as the CycleScheme voucher comes through, and I have a spare set of carbon Chorus cranks...
