The following genuine VDO parts are available at your Bike Shop
- set sensor/cable/stem mount (support rotated by 90°)
- set sensor/cable/handlebar mount
- set sensor/handlebar mount/cable 1.5 m for rear wheel mounting
2.1 Mounting cable sensor and magnet
Important: mount the sensor first, then mount the wired handlebar holder as described under

a. Distance between the sensor and magnet: 1 to 5 mm

b. When mounting the sensor on a suspension fork, don’t forget to allow extra length for the
cable.
WATCH OUT: cable may tear
step 1 Loosely attach the sensor on the fork leg with cable ties
(do not tighten yet).
step 2 Mount the magnet on a spoke. Adjust the magnet to the
marking on the sensor (distance 1-5 mm).
step 3 when unit is working, finalize transmitter and magnet
mounting by tightening cable ties and clamping the
magnet
2.2 Mounting cable and VDO “any-size” handlebar holder
step 1 Run the cable up the fork, pass it around the brake cable from the already fixed sen-
sor to the handlebar. Use the enclosed cable ties or duct tape. Spiral the wire around
the brake cable (this has proven to be the best solution).
step 2 position the holder on the handlebar.

step 3 feed the fixing clamp through the slot below the holder socket, pass the clamp
around the handlebar and tighten it with a small screw driver. Do not overtighten, the
plastic screw might be damaged. Readjust the cable so that it will not be stretched
during steering. Finally tighten the zip ties holding the sensor.
2.3 Battery Installation (computer)
Your VDO computer comes with a 3 V battery (type 2032).
step 1 insert the battery into the computer, positive pole face-up
step 2 watch out not to edge over the battery
step 3 watch out that the rubber washer lies levelled on the inside
of the battery compartment.
step 4 insert the battery door into the opening, twist it with a coin
to the right until the stop after approx. 1/3 turn.
Battery Change
TIP: VDO recommends an annual battery change. Buy the spare battery from your Bike Shop
