Single Pulley

The Chain Reactor wraps the chain further round the front ring to prevent it ‘flapping’ and getting thrown off over rough terrain. Chain Reactors come with a sealed bearing PU pulley as standard or run the optional Dual pulley and a Sideplate to keep the chain on and the tension constant in both front gears. Designed to run with geared chains (not singlespeed).

Dual Pulley

The dual pulley and a Sideplate to keep the chain on and the tension constant in both front gears. Stiff stainless steel construction and a seat tube clamp mean this device runs true and stays locked once you’ve adjusted the tension. The Dual Chain Reactor comes with ISCG or standard BB mounting patterns. Designed to run with geared chains (not singlespeed).
