38T Chainring suitable for Brompton!

If you want to try a hill climb ride with your Brompton, you might adopt a 38T chainring.

I purchased Sugino 130J-PCD130 (38T) and changed from the original 44T. 38T is the minimum size for PCD130. You can realize that the diameter of a Brompton Spider crank is just the size of a 38T ring.
