  Brompton G Line Chains

  The Brompton G Line (the 20 inch wheel version of the Brompton folding bike introduced in 2024) comes by default with a 54T front chainring

  G Line chain lengths

  • 114 links is what is used on the default 54T chain ring
  • 112 links would be used if you changed from 54T to 50T to reduce the gearing
  • 110 links would be used if you changed from 54T to 44T to further deduce the gearing

  We currently only stock the one length of chain - but if you order and add a note with your chainring size we can cut the length to chain as requested before shipping
