Brommiemods is a small business that took over production and supply of Brompton metal chainguards and mudguards from Tiller Cycles. It was Graham Varcoe at Tiller who invented the metal chain guards and mudguards that are so superior to plastic in both looks and durability. He took it upon himself to manufacture them in his workshop on a canal boat and sell to the Brommie masses. We at Brommiemods are continuing and expanding on his good work. Order your Brompton-compatible chain and/or mudguard with 100% confidence. Satisfaction guaranteed!
