While the current Roller Wheels that come stock on Bromptons are improved over the pre-2016 plastic rollers, the good old Brompton Eazy wheels with cartridge bearings are hard to beat . Eazy Wheels are a slightly larger diameter, have good quality sealed bearings in them and are just soft enough to absorb the bumps when rolling the bike on a sidewalk or rough pavement. Also they don't cost a fortune like the CNC-ed ones so if you managed to destroy one you don't have to break the bank for a replacement roller.
