I love my 2017 Superlight Brompton, but not so keen on the stock bottom bracket and would also like to shave more weight off. I've read that some use a Specialites T.A. Axix Light Bottom Bracket, will this fit a 2017 Brompton and have keep the correct chainline? If so, which size do I need? Was assuming 119mm and BSA (1.37x24) thread? It's expensive, but I understand has replaceable bearings.
Phil Wood does very nice bottom brackets, but then the price does start to get silly...
