56T Chainring for the Brompton T Line Drivetrain The Brompton Superlight Direct Mount Chainring 56T is the high-tooth-count option for riders running the T Line's Superlight Carbon Crankset. The larger 56T ring raises the overall gearing, giving you more top-end speed for flatter routes and faster commutes without changing anything else in the drivetrain. As a direct-mount design, the ring fixes straight onto the carbon crankset's spider rather than relying on a separate bolt-on adapter, which keeps the interface clean and the weight low. It is matched to Brompton's Advance Superlight chain and is intended specifically for T Line builds. Built for the Superlight Drivetrain 56-tooth chainring raises gearing for higher cruising speed on flatter terrain. Direct-mount interface fits the Brompton Superlight Carbon Crankset without a separate spider or adapter. Lightweight construction in keeping with the T Line's titanium build, at roughly 0.64 lb. Designed to run with the Brompton Advance Superlight chain. Finished in black to match the T Line drivetrain.
