CHAINRING & GUARD
The Genuine Brompton replacement Chainring & Guard is suitable for the Brompton Spider crank which has the replaceable chainring fitted to all new Brompton bikes since 2013.
Available in all three Brompton chainring sizes, so if you find you need an easier or harder gear (or have simply worn yours out) then this is for you. If you have worn yours out then we recommend changing the rear cogs and chain at the same time.

Brompton is the only company we've seen that answers all three criteria - and believe us, we've tried every brand out there. The reason others can't compete is because Brompton has answered a fundamental engineering problem. If a bike is going to unfold to a large footprint (which takes the twitch out) then it is unfolding to a bigger bike - and by all logic, a bigger bike unfolded would be a bigger bike folded. So, it's pretty much true that for most folding bikes they either have great rideability but poor transportability or vice versa. And nearly all of them are a mess to fold.
Not Brompton. Brompton has designed the Platonic form of all folding bikes. The bike folds to the smallest size on the market, unfolds in a highly precise and easy manner, and has the same axle-to-axle footprint as a hybrid bike. How did they do this? By not only designing a clever frame, but also designing some 1200 proprietary parts that make everything fit - and fit perfectly. Oh, and nearly all of this is made in England. No wonder this bike has a cult following.
