Higher Gearing Option for More Speed on Flatter Routes
This 54-tooth chainring and guard assembly is made for Brompton’s Spider Type crankset, combining the chainring and protective guard in one clean replacement. It’s a practical fix when your current ring is worn, or when you want a taller top gear for quicker cruising.
Compared with a 50T chainring, 54T raises gearing by about 8%. If you change chainring size, a different chain length may be required to keep proper tension and folding function.
Design That Works
- 54T chainring for higher gearing on compatible Brompton Spider cranksets
- Integrated guard helps protect clothing and keeps the chainring covered
