In this article I am looking at the Quarq ELSR RS power meter which has been kindly given to me to use on my training bike in conjunction with Shimano Ultegra 6800 group set. Quarq is an American based company which was founded my Jim and Mieke Meyer who design a variety of power meters to suit all disciplines of the cycle sport. I have been using the Quarq ELSA RS now for around 18months and haven’t once regretted the choice and selection. There was a moment in time where I was considering other types of power meters and was talked around to having and using the ELSA RS. For me, both as an amateur and time crunched athlete I was sceptical about a few things regarding the power meter. 1. Was it going to be accurate? And how accurate? As for me compared to some others, numbers mean everything! 2. What was it going to be like to use in adverse weather? i.e. could it cope in cold wet weather in temperatures that were likely to be around the 5®C? As most of my training takes place either early morning or evening times 3. Easy to install and maintain? 4. And finally, measurement of both legs output? The ELSA RS does everything! It is accurate to +/- 1% which for me as an amateur athlete is perfect! But due to suffering a little from OCD I had to have this checked and so did bike fitness test whilst using my own bike on a stand-alone turbo trainer which had its own method of measuring power the two weren’t too far dissimilar. Not only this but the ELSA RS copes in all conditions, one recommendation is to always dry the unit and cranks following a wet cold ride as to prevent any issue with the unit; but, as to date, and by the way heavy usage during adverse weather, have not had any issues with the power meter! The system is easily installed on a GXP, Press Fit GXP, BB30, Press Fit 30, BBright, BB386EVO. One thing which does hang me up is, the system is built for the DuraAce chain rings however still works perfectly with ULTGRA rings no problem however the rings don’t sit flush with the chainset spider. My training, my riding and my fitness/ability has massively improved (obviously not only just my power output) because of the power meter. I found that the system averages zeroes when you are riding therefore I found myself pedalling through the crests of hills and downhill and more so on flats. I didn’t want my averages ruined so I just started pushing harder which has upped my outputs massively and increased my fitness twofold!!! The important point to me is that the system is easy to use! And easy maintainable, the only thing is the system is expensive, but if you want a reliable easy to use system, it’s well worth the cost!
