Drop Your Gearing, Climb More Confidently
Lowers Brompton's stock gearing for climbing hills by 12%. Your top speed will be reduced by the same amount.
The Brompton Chain Ring + Guard Spider 44T is a direct replacement chainring for Brompton bikes equipped with the Spider-type crankset. Swapping from a 50T to this 44T reduces your gearing by approximately 15%, making hills noticeably more manageable without requiring a drivetrain overhaul. It's a straightforward, effective upgrade for riders who want a more comfortable cadence on hilly commutes or loaded rides.
The integrated guard spider protects the chainring and keeps the drivetrain clean, maintaining the tidy, compact look Brompton is known for. Compatible with all Brompton Spider chain sets, this chainring also replaces 50T or 54T setups, giving you flexibility to dial in exactly the gear ratio that suits your riding style and terrain.
