I''m looking to bling up my Ti Brommie with a SRAM One chainset.
Two things; can anyone confirm the BB fitting is a standard BS thread, please?
Secondly, the existing chainset is a standard 'spider', purchased in 2014 which is stated to come in 50/52/54t sizes. However, I've counted the teeth on the existing one and make it 53. I've checked it three times.
Is that the case? Only asking, because the Sram option is a 52, and I need to replace like with like because of the picky Brompton chain length requirements.
Thank you!
Paging @Mr Orange and @AKA Bob for help?
