Description
Spin Less, Cruise Faster on Your Brompton
If your Brompton came with the low 44T chainring and you keep spinning out on faster rides, this 50T ring and guard is the clean way to step things up. It’s a genuine Brompton spider-type chainring assembly that bumps your gearing by about 14%, giving you a higher top speed and calmer cadence on flat commutes and longer rides.
The integrated chainguard keeps clothing clear of the chain while preserving the tidy fold. Because it’s built for Brompton’s spider crankset, it swaps straight over in place of a 44T spider ring with no surprises at the crank—just be prepared to adjust chain length when you size up.
What Sets It Apart
- Ideal upgrade from 44T to 50T for riders who want more speed.
- Genuine Brompton spider-type chainring and guard assembly for a factory-correct fit and finish.
- Black finish pairs especially well with Black Edition and other dark-spec Bromptons.
- Direct replacement for 44T, 50T, or 54T rings on Brompton spider cranksets (2013 onward).
- Integrated chainguard helps keep trousers and skirts away from chain grime.
