  Brompton folding detail

  Brompton folding detail, joints, frame clamps etc

  As you probably have noticed by now, the Brompton is a folding bike. This means it has specific parts which help with the folding mechanism, such as frame clamps, handlebar catch and front axle hook

  Some of these are tough plastic - but that means they can become brittle with age / exposure to light - so eventually they will need replacing

  The suspension block is a softer rubber like material - and over time this can wear / split - there are also two versions, standard and firm (firm is recommended for people over 75kg or wanting a more sporty ride)

  We also have (for those older Brompton bikes out there) the retrofittable rear frame clip - this stops the bike from automatically folding every time you pick it up (e.g. to carry up some station steps)

  Brompton Headset

  Replacement Brompton headsets and headset related parts

  For 16 inch wheel size Brompton

  With the introduction of the T Line (titanium lightweight model) Brompton - the headset used on a Brompton diversified

  Traditional Brompton headsets

  The traditional Brompton headsets are now available in steel (and in black or sliver) and aluminium models (for a very slight weight saving) and are used on the following models:

  • Brompton A Line / B75
  • Brompton C Line (Core)
  • Brompton C Line Electric 
  • Brompton P Line (Performance)
  • Brompton P Line Electric

  These traditional headsets are compatible with all the above Brompton models

  T Line headset

  The T Line headset is more similar to a mountain bike Aheadset

  Brompton rear racks...

  Brompton rack / advance roller rack and sccessories

  The Brompton rear rack now comes in two designs and two colours

  • Brompton standard rear rack - silver
  • Brompton standard rear rack - black
  • Brompton advance rack - black - for P Line / T Line

  The rear rack serves two purposes

  • Makes rolling the Brompton easier when the bike is folded
  • Allows carrying of things on the back of the bike when not folded

  The Brompton rear carrier is the perfect size for transporting a 16 inch pizza. We know this because we use these pizza boxes for transporting Brompton tyres, which we sometimes deliver by Brompton!

  Here you can find the complete racks to upgrade your bike if it did not have one and spare parts should you break the one you do have

  Note: The standard rear rack is also suitable for the Brompton Electric folding bike (though not offered as a factory fit option)

  Brompton roller wheels

  Brompton rollers, Eazy Wheels and roller spare parts allow the wheeling of your Brompton about when folded

  All Brompton come with roller wheels on the rear and the standard ones have been improved over time

  Where are these roller wheels (we're talking C Line and older here)

  • There are two on the rear frame just by the seatpost - these use a 6mm bolt and are known as forward roller wheels
  • If you have mudguards but no rack there is a single one on the mudguard
  • If you have a very old rack it has 2 roller wheels with 5mm holes
  • If you have a newer rack it has 2 roller wheels with 6mm holes and are known as aft roller wheels

  Some roller wheel history

  Older Bromptons had cone shaped forward roller wheels - which broke if treated too harshly - partly to protect the frame from bending. These have now been replaced with more robust wheels, which are also slightly narrower - reducing the risk of heat-stroke or catching your ankles on them

  Eazy Wheels

  Eazy wheels (why not easy wheels?) facilitate easier rolling of the Brompton when folded - turning your expensive bike into an awesome shopping trolley (especially welcomed in Waitrose). They have a slightly larger diameter than the standard roller wheels and bearings to help them roll even better

  Advance roller wheels

  These were introduced with the P Line and T Line - but are compatible with previous model Brompton folding bikes - they have a slightly larger diameter but no bearings
