Welcome To ShockClock - 3.3.2 Rear Transducer

Mount the Transducer above and behind the rear axle to the seat post on the right side of the bike (gear cluster side). Check that there is clearance throughout the entire travel. Zip tie the cable to the Transducer Head with a big loop. Make sure it is out of the riders' way.

> Upper Rear

Use the Seat Post Bracket supplied. Mount the flat strap on the right side of the seat post. Mount the Wave-Guide Clamp on the outside (right side) of the strap and use a spacer to give the head clearance from the bracket strap.

Securely zip tie the Transducer Cable and route it where there is no chance of snagging it. Put a large loop so the rotation of the Transducer doesn’t break the cable.

Be sure to grease the o-rings in the clamp.

> Lower Rear

Mount the flat Bracket Strap on the right side of the bike (gear cluster side) with the axle clamp. Angle the strap up about 30 degrees from horizontal (this is not critical and can be adjusted to get proper travel).

Mount the Wave-Guide Clamp on the inside of the bracket (toward the gear cluster). Check the clearance of the chain for gear changes.

You may need to temporarily remove the little conical spring on the bracket side of the axle.

If you have an oversize axle you may need to make a custom bracket.

Be sure to grease the o-rings in the clamp.

> Check Travel

Remove the spring from the shock or let out the air on air shocks. Re-install the shock on the bike and bottom it out. See 3.4 Adjusting the Tubes.

> Convert to Vertical

The “Laid-Down Data” is not “Vertical” Wheel Travel. This is now easily converted with the PC or PDA. See 9 - Convert to Vertical - Dirt

Auto-Convert - PC or PDA

The Laid-Down data can be converted into Vertical data automatically while downloading. This requires measuring the geometry of the Laid-Down Transducer with a tape measure and inputting it into Default Vehicle Preferences. Check the Auto-Convert check box.

Convert to Vert (Edit Menu) - PC only

If you did not setup the software to auto-convert upon download you can still apply the "Laid-down Geometry" using the "Convert to Vert" in the File Menu. This will apply the current Default Vehicle Laid-Down Geometry in Vehicle Preferences to the data in File location 1 only. (Measure the geometry of the Laid-Down Transducer with a tape measure and input it into the current Vehicle Type in Preferences before applying.)

> Measure the Laid-Down Transducer Geometry

> Measure with a metric tape from pivot center to center and input into Vehicle Preferences (Prefs/Setup). All distances are in millimeters (mm).

L1 = Swingarm pivot to upper transducer pivot
L2 = Upper transducer pivot to lower transducer pivot
L3 = Exposed maximum transducer travel
L4 = Swingarm pivot to lower transducer pivot
L5 = Swingarm pivot to rear axle
L6 = Perpendicular distance from swingarm centerline to lower transducer pivot (not necessarily the bracket length)
L7 = Swingarm pivot to the ground (bike level) (accuracy not too critical)
L8 = Rear axle to the ground (bike level) (accuracy not too critical)

> Input Maximum Available Wheel Travel

See Vehicle Preferences

> Conversion Test

Input a Laid-Down Transducer Travel and it will display the corresponding Vertical Wheel Travel. Note that when you input Transducer Travel that is too high the Wheel Travel displays "N/A". What this means is that at some Transducer Travel the geometry is impossible mathematically. This will also show you how much Transducer Travel you need for the Maximum Available Wheel Travel.

It is possible to mount the Transducer in an impossible configuration. There must be enough Transducer Travel available as well. To check this, input the Transducer Mounting Measurements in Vehicle Preferences along with Maximum Wheel Travel. When you click the OK button it will check the configuration and give an error message if there is a mathematical problem.

It is also possible to mount the Transducer Head too low so it hits the swingarm before bottoming. Use a tape measure at the rear axle to indicate the available rear wheel travel. Lay a rod on top of the swingarm at the pivot up to the bottomed-out position of the swingarm. Make sure there is clearance.

Axle position affects the maximum available wheel travel. If the axle is mounted forward the travel will be slightly less and if it is mounted to the back the travel will be slightly more. If you want to know exactly you must disassemble the shock, remove the Bottom-out Bumper, reassemble and mount the shock then measure the travel.
