INSTALLATION

MOUNTING THE HANDLEBAR BRACKET

Fit the rubber pad to the back of the handlebar bracket and use the nylon ties
to attach it to the bar. Do not fully tighten the nylon ties until you’re certain the
angle of the computer is correct. (figs 1, 2).

Place the cycle computer on the bracket and secure it by turning clockwise
(fig 3).

MOUNTING THE SENSOR

The sensor is mounted on the non-driveside chainstay, just behind the bottom
bracket. The distance between the computer head unit at the handlebar and
the sensor should not exceed 150cm.

The larger part of the sensor reads the crank arm magnet to register cadence,
etc. The adjustable arm of the sensor unit registers speed, distance, etc.
The larger part of the sensor faces the front of the bike, and the adjustable arm
faces the back and sits along the inside of the chainstay. Loosen the knurled
dial in front of the adjustable arm to rotate it in the optimal position (fig. 4).
Do not tighten it until the optimal position has been determined.

Place the included rubber pad between the sensor and the chainstay.
The sensor is attached using two included zip ties, but do not fully tighten
them until the wheel and crank arm magnets are in place, and the adjustments
that yield the best readings are made between the sensor, sensor arm, and the
magnets (fig. 5).

The distance between the crank arm magnet and the sensor, and between
the rear wheel magnet and the sensor arm should not exceed 3mm.

MOUNTING THE CRANK AND WHEEL MAGNETS

1. Place the crank arm magnet on the inside of the crank arm 2 to 3cm up the

arm from the pedal spindle and zip tie it in place.

2. Position the larger part of the sensor close enough to the crank arm that the

required distance between it and the crank arm magnet is achieved (fig. 6).

3. Using this sensor placement as a guide, position the wheel magnet in the

approximate area that it will pass the sensor arm on the inside of the
chainstay. The wheel magnet is tightened to the spoke by threading
it into the magnet bracket that sits behind the spoke (fig. 7).

4. Holding the larger part of the sensor in place with one hand, rotate the arm
of the sensor so that the required distance between it and the wheel
magnet is achieved.

5. Use two zip ties to tighten the sensor to the chainstay, and snip off the
excess length.

6. Make any final adjustments to the sensor arm to achieve the required
distance between it and the wheel magnet, and tighten the knurled dial.

7. Test to make sure that the magnets are activating the sensor, and the
computer head unit is registering the magnets as they pass the sensor.

WHEEL SIZE CHART

CALCULATING WHEEL CIRCUMFERENCE

To get the most accurate speed and distance data, the wheel size must
be correct. Mark the tire or position the valve stem at the 6 o’clock position
and push the bike until the mark or valve
stem is back to 6 o’clock. Then measure
the length between two points to get the
circumference.

Refer to the wheel size chart for diameter
and tire width. If your wheel and tire size
is not listed, use the following wheel
circumference equation:

Circumference (mm) = 2 x 3.14 x R (inch) x 2.54
(1 inch = 2.54cm), R = radius in centimeters.
