Our Stages Power meter is the singular product that will bring power measurement and training to the masses. Stages Power has an impressive range of adaptation over the industry's aluminum crank models. This range puts power meters within the reach of every performance minded rider, from road, to triathlon, to mountain bike (including downhill), to BMX and track. It's a simple solution is tailor made for Shimano's entire performance range, as well as SRAM's aluminum Rival and X9 models. For BB30 riders, we offer SRAM’s X9 mountain model and we’ve brought on Cannondale's new
Hollowgram SI SL crank set, as well as their more economical 3D forged Hollowgram SI crank, both of which are new for 2013.
In a nutshell, it’s a power measuring device manufactured in Colorado that’s affixed to the inside of a bike’s non-drive side crank arm, and uses strain gages to determine power output by measuring deflection (aka extremely subtle microscopic bending) of said crank under load. Each strain gage is specifically calibrated to the crank it’s mounted on. The unit takes 64 discrete measures per second, which is far more than necessary for road riding, but could have interesting applications in the track, BMX and even downhill mountain biking world where rapid acceleration is key to success.

Weaknesses: If you have carbon cranks you must use an aluminum crank on the non-drive side. For example; for Sram Force and Red you must use the Rival left arm.
Bought unit used from ebay back in January 2014. Easy to set up and works with ANT+ or Bluetooth Smart devices. Takes power ready from the non-drive side and averages it for the drive side. My unit was Sram Rival mated to the Force crank. Did not notice any difference using the Rival left side vs. the Force. A little heavier but not much. Unit worked great and registered consistent power measurements. In May I experienced some issues with the meter after battery replacement. Went through some troubleshooting with Stages support for a few days. After being unable to resolve the issue with the meter ready Stages informed that they would be sending me a new unit. I was shocked. I was already resigned to the fact that this would surely cost me something as I bought the unit used and there was no chance the warranty would still cover it. Support did confirm that the unit was beyond warranty but that they would replace the unit regardless. OK, when is the last time that happened! Great company and now being used by team SKY for their power measurement. Easily half the price as other power meters on the market.
hey guys... so I'm wondering if anyone here has a Stages power meter. I'm currently using a Garmin Edge 510 with Garmin GSC10 for cadence and speed. It's my understanding that the Stages measures cadence, but I'd still want to keep my GSC10 for speed... so how would that work out?
Also.. I'm runnin ... Read More »
Looking at a Stages PM Hollowgram Si crank...but I have one possibly really stupid question: You're required to order a brand new left crank arm from Stages but if you already have a full set what do you do with the non-Stages left arm once the new arm is installed? Google did not shed any light o ... Read More »
Does anyone actually [I]have[/I] the Stages power meter on their Madone 5 series or above? Stages' website says that the crank arm power meter will work as long as the rider does not use Shimano branded direct mount brakes. However, they state that there is very little clearance and if t ... Read More »
I have both the Powertap G3 and Stages. Friend of mine also has a Stages, and before this he also had a Powertap (but he no longer has his Powertap).
anyway, we both tested our Stages power meters against my Powertap G3, and both Stages meters (his and mine) report about 11% - 13% lower in wattage ... Read More »
