Cadence Magnet Installation

Before assembly

 

• 

The cadence magnet must be installed properly in order for the PowerMeter to turn on and measure cadence.

• 

The recommended position for the cadence magnet is on the underside of the bottom bracket.

• 

Make sure the magnet is positioned between 21-51 mm from the center point of the bottom bracket shell. (Fig. 7).

• 

If your frame geometry does not allow for these magnet positions, visit our store at 

www.SRM.de

 for 

integrated chain catcher magnets and additional mounting options.

Option 1: For frames with a cable guide

• 

Remove the cable guide bolt and install the magnet under the cable guide (Fig. 8).

• 

To assist with cable guide removal, shift the chain into the largest cog in the rear and the largest chainring in 

the front. Next, without turning the cranks, shift both derailleurs to the smallest cog. This will remove tension 

from both cables.

• 

Position the magnet 4-6 mm from the backside of the PowerMeter (Fig. 9).

• 

Install the bolt and tighten it to the torque specified by the frame manufacturer - you may need a longer screw 

to securely hold the cable guide and magnet in place.

NOTICE

The derailleurs may require some adjustment after cadence magnet installation.

Option 2: For frames without a cable guide

• 

Clean both the magnet and the mounting surface of the frame with the isopropanol alcohol.

• 

Position the magnet 4-6 mm from the backside of the PowerMeter (Fig. 10).

NOTICE

It is recommended to temporarily fix the magnet in place and confirm correct position before installing with 

the double sided tape. Check the functionality of the PowerMeter before gluing the magnet!

 

• 

Use the double sided tape to install the cadence magnet to the frame. Remove the protective film on each side 

of the tape. Avoid touching the adhesive surfaces. Glue the magnet in the correct position.

• 

To achieve optimal magnet position, the cadence magnet and double sided tape can be cut with scissors to fit 

your desired location.

Connection

• 

For information on connecting the SRM ORIGIN PowerMeter to your SRM PowerControl or other third party 

ANT+ devices, please refer to the device manual.

NOTICE

Make sure your PowerMeter is turned on when pairing to other devices! Spin the crank 1-2 revolutions to 

turn the PowerMeter on! Check cadence magnet placement to ensure function!

Battery Test / Replacement

• 

The SRM ORIGIN PowerMeter broadcasts the battery status to the SRM PowerControl or other compatible 

ANT+ devices. You will get notified if the battery is running low!

• 

See our authorized dealers or us directly at 

www.SRM.de

 for a battery replacement.

WARNING

Danger of explosion, in case of improper opening of the PowerMeter or replacement of the battery.

NOTICE

Unauthorized opening and closing of the PowerMeter can lead to water leakage and permanently damage. 

The SRM ORIGIN PowerMeter is equipped with lithium batteries which can only get replaced by authorized 

SRM Dealers or the SRM Service Centers!
