Araxy Erion uses magnets to control chain movement for downhill vibration damping
Swiss brand Araxy has launched Erion, a system made of two magnetic modules fixed to the chainstay that hold the chain when it is unloaded and, according to the brand, release it immediately when pedalling resumes. Araxy says the design can reduce vibration transmitted to the rider through the chainring and cranks, and it presented a vibration-transfer measurement chart said to be produced with Downamics.
Why it was selected: A Swiss brand uses magnets to constrain chain movement while coasting, and the installation conditions and compatibility limits are described in specific detail.
