SCHLUMPF MOUNTAIN-SPEED.DRIVE 2:SPEED GEARBOX CHAIN.SET

Precision‑engineered drivetrain solution designed for riders who demand both simplicity and performance. At its heart lies an ultra‑thin (just 10 mm) planetary gearbox that neatly integrates with your chainring, with no bulky mechanisms, no extra cables or derailleurs. Shifting is ingeniously simple: a gentle heel tap on the side button lets you engage the alternative ratio, either a 1 : 1.65 overdrive in the Speed‑Drive version for higher speeds, or a 1 : 0.40 reduction in the Mountain‑Drive version for climbing with ease. Built with premium materials and designed to take full torque in both pedalling directions, it’s equally compatible with fixed‑gear and coaster‑brake setups. This compact, low‑maintenance gearbox gives you a minimalist look with maximised versatility. • • • • • • • • • • • • • • • • • • • • • • Change gear with a simple kick of the heel on the side buttons, while standing still or under heavy load. Low maintenance. No cables, levers or derailleurs. High efficiency, high quality materials, ensure great longevity. Symmetrical clutch allows full torque in both pedalling directions, making it compatible with coaster brakes and fixed-gear bikes without a rear brake. The optional EASY-SHIFT plates, available on request, cover the whole crank arms and allow for shifting by pushing on a larger area, best for clip-in pedals. SPEED-DRIVE ratios: 1x direct-drive and 1.65x overdrive. MOUNTAIN-DRIVE ratios: 1x direct-drive and 0.4x reduction for even the steepest climbs. • • • • • • • • • • • • • • • • • • • • • • Chainring not included • • • • • • • • • • • • • • • • • • • • • • More on our ‘MEDIA’ page.
