*Important notification: Around 2019, Brompton made a modification in the design of the front fork that affected the design of the brake calipers, which now require of a shorter fixation screw for the front caliper. Newly manufactured Ridea BCB3 calipers are designed to work with the new Brompton design, although Ridea dealers may have older versions in stock with a longer screw. We recommend that consumers seek advice from Ridea dealers before purchasing to make sure that they are acquiring the right brake calipers for their Brompton bikes. New (shorter) screw is 38 mm long, while the old (longer) screw is 52 mm long.
