What is a SRM system?
Supplier relationship management (SRM) is the systematic approach to evaluating vendors that supply goods, materials and services to an organization, determining each supplier’s contribution to success and developing strategies to improve their performance.
How do I change the battery in my SRM power meter?
- Step 1 Open the Power Meter. Remove the chain rings.
- Step 2 Remove Batteries. ATTENTION: Make sure you don’t damage the thin cooper wires marked in yellow.
- Step 3 Prepare new Batteries. My batteries had mounting pins attached to the silver side.
- Step 4 Attach Wires.
- Step 5 Insert the Batteries.
Is a left sided power meter worth it?
If you don’t care about 100% accuracy and wanna save money, there’s nothing wrong with a single sided power meter. (Make sure it’s a left crank if shimano based) An improvement on single side means you’ve made improvements overall in performance so it’s something still worth tracking.
Is single sided power meter enough?
‘ Despite the claims of many power meter companies, there are actually very few that can measure the two legs separately. To isolate the right and left leg truly, you effectively need two power meters in a single system, one to measure the output of each leg.
What is zero offset calibration?
Zero offset calibration is the process in which the zero offset value is updated for the power meter. This is an important process as it ensures the power meter has an up to date value for 0 (or no load on the power meter). Depending on the head unit used, this process may be referred to as calibration or zero reset.
Is SRM power meter compatible with Garmin?
ANT+ COMPATIBILITY The SRM Wireless PowerMeter is ANT+ compatible. There are a number of ANT+ bike computers on the market (e.g. Garmin) which will connect with the SRM PowerMeter; however, SRM can not guarantee that data displayed on third party head units is accurate to the standard of the SRM PowerControl.

What are SRM tools?
Supplier relationship management (SRM) involves the effective and appropriate management of a procurement professional and their supplier. Good SRM involves creating closer, more collaborative relationships to maximise value and reduce risk.
Are dual sided power meters more accurate?
‘One-leg systems give a false sense of accuracy,’ says Justin Henkel, product manager at PowerTap. ‘A simple imbalance of 3% becomes 6% when you’re measuring from one side and doubling it. And 6% of 300 watts is nearly 20 watts.
How long do power meters last?
On average, an electric meter can operate effectively for 25 years. Certified to American National Standards Institute (ANSI) criteria, these meters can have life spans far longer than consumer products. The same goes for gas and water meters (average life spans, 25 and 15 years respectively).
SRM pedal power meters have a senor in each pedal and therefore can measure the power from both legs in addition to independent left/right power. What sets the SRM power meters apart is their accuracy. They have been making power meters longer than anyone and have the process down to a science.
How much does an SRM weigh?
Most SRMs run in the 600-800 gram range, with the SRM Origin weighing in at 599 grams, the lightest of the bunch. Remember, when buying a power meter, you are concerned about added weight.
Do SRM crankset power meters measure left/right power balance?
SRM crankset power meters measure power at the crank spider. Therefore, they measure both left and right leg power. However, unlike some other crankset-based power meters, they do not measure left/right power balance.
