The Bosch Purion display is a direct replacement part. The Purion display is available in 2 configurations designed to work with either the Performance Series (Anthracite color) drive units or the Active Series drive units (Platinum silver color).
Each Bosch Purion display comes with handlebar mounts and cable. Note that removal of the non drive side crank arm and cover is required. In order to remove the crank arm you will require a crank arm puller.
