Brompton Rear Mudguard Blade & Flap Only This replacement rear mudguard for Brompton bikes is available in two versions. The silver version is for a Brompton without a rear rack, so you'll need a set of stays (not supplied) to fit it The black version fits a Brompton with a rear rack Note: Both mudguards are supplied without fittings - the idea here is that if your mudguard gets damaged, that's the only part you'll have to replace. Simply use the original's stays or rack fittings to mount the new mudguard.
