Brompton Components

All Bromptons undergo strict testing and adhere to relevant ISO and EN standards but with time you might need replacement parts.

A big plus point about owning a Brompton is how convenient it is to find spare parts or upgrades. These parts and upgrades are readily available in lightweight materials such as aluminum, titanium, stainless steel, etc which encourages enthusiasts who prefer less fuss with bike maintenance.

Sometimes people simply want to upgrade and make the bike even lighter than stock condition.

No matter if you’re to upgrade or replace wearing parts, PerennialCycle offers a huge inventory of Brompton parts and upgrades. We carry both original Brompton parts and parts from third party vendors. Be it the brakes, sprockets, gear parts, transmissions, or wheels for your Brompton - we have it all. We can also help you stock up replacement parts that are hard to find.
