Small Derailleur Parts That Keep Shifts Clean and the Fold Working Right
This replacement set refreshes the chain-guiding pieces on Brompton derailleur-style drivetrains. If shifting starts to feel inconsistent, noisy, or the chain isn’t tracking onto the sprockets as smoothly as it should, worn guide parts can be a quiet culprit.
The kit includes the chain pusher and wing plate, which work together to help guide the chain during gear changes and keep chain management behaving through everyday riding and frequent folding.
