103 SPX/RCX (ref: 279498)
The ER1 variator is only available for SPX/RCX. It mounts on the original fixed flange, hence its attractive price. Its roller-ramp conception offers it a precise and easy adjustment. Its patented 1/3 lap notch system offers to change the roller weights without removing the variator. It's a considerable time gain for setting. The moped variators are nickasil-treat to provide longer durability.
