Formula’s Nero DH fork comes in coil and air-sprung versions, for 650b or 29in wheels. Both share the same damper, which allows high and low-speed compression adjustment. The air-sprung Nero R uses a three-chamber system, dubbed ‘3Air’. This allows you to adjust the end-stroke progression (gold valve) and both positive (silver) and negative (bronze) pressures to tailor the spring curve. Pricing should be competitive.
