    Chains for Brompton Folding Bikes

    Servicing bikes is taken very seriously at Perennial Cycle. Brompton Bikes are a big part of our service department. It's only natural that we would offer the best chains that you can install on your Brompton Folding Bike to make it shift quickly and run smoothly.

    While the stock (OEM) chain is functional in a gets-the-job-done kind of way, the chain is the heart of your bike's transmission and thus a great component to upgrade to help you get the most out of your bike. Being that the Brompton chain is a basic OEM chain, we feel pretty strongly that it doesn't match the quality of your amazing Brompton Folding Bicycle.
    Below are 3 choices that we like a lot:

    -

    Connex 8sX by Wipperman
    The Connex 8sX is the best. Hands down.
    Manufactured in Germany using the best tech available. The stainless steel plates with nickel inner links make this a weather-proof chain that is highly wear resistant. Expect an extra 40% life from the 8sX as well as improved shifting. The included Connex Link is known to be the most dependable quick link available.
    This is not an inexpensive chain, but it is a great value.

    -

    Connex 808 by Wipperman
    The Connex 808 is a full nickel chain (both inner and outer plates). It can handle the weather better than most chains on the market. Also the chain plate design is the same as the 8sX, so shifting will be smooth and quick. The Connex Link (included) is legendary for being extremely dependable.
    Though the 808 is not manufactured in Germany, it is quality tested prior to packaging in Hagen, Germany.

    SRAM PC 850 Powerchain II
    The SRAM PC 850 is the best chain that you can buy for under $20. Uses SRAM's Powerchain II technology and comes with a SRAM Powerlink for tool-less installation. A clear step up from the Brompton OEM chain, yet keeping things very economic.

    The length of the chain is determined by the gearing on your bike. The chart below is what we use to get the chain length correct for each Brompton we're working on.
    If you need help working out which length chain you need, feel free to give us a call: 612-827-8000

    If you buy a chain and you choose the number of links you want it to be, we'll measure it and send you the chain as requested along with the quick link. This way you would not need a chain tool on your end.
    BTW: If you are going on a trip or tour, having a spare connecting link could end up saving the day. Find the connecting links with the chains.

    Extra Details: If your chain needs replacing, we'd expect you to also need to replace the sprocket(s) on the rear wheel. These are available HERE. Replacing your chain and sprockets is a simple way to keep your shifting smooth and your drivetrain running quietly.

    Extra Extra Details: Older Bromptons used 1/8" chains, instead of the current 3/32". We don't expect to put any 1/8" chains on Bromptons. The current sprockets available are for 3/32" chains, so if you currently have an 1/8" chain, we'd be replacing the chain and sprocket with 3/32" sprocket and 3/32" chain.
