— New Lower Pricing on Stages Power Meters —

Stages Power has carried riders to three consecutive Tour de France victories, plus many more world and national championships. If you believe racing provides the world's best product proving ground, then Stages Power is proven as the world's best power meter. Featuring Active Temperature Compensation as standard equipment, Stages believes that consistency of measurement is the most important feature of a power meter. Stages Power was the first meter to make temperature compensation an automatic process ensuring accurate readings regardless of the environmental conditions. Stages Power meters are calibrated individually to ensure a +/- 1.5% accuracy level which means that you can trust the data produced by their system.

The new Gen 3 single-sided Stages Power meter for Cannondale Si Stages Power meter is built on to a non-drive-side Cannondale Si crank arm and is compatible with existing Cannondale Hollowgram Si crank models - 2014 or newer and Hollowgram SiSL2 cranks.

Stable and reliable, if a bit finicky
by Anonymous

I've been riding a Stages Power Meter on my main road bike for years and picked this one up for my gravel bike. What can I say about it? It's stable and reliable, though the readings vary a bit compared to my other meter. I can offset the discrepancy in my head as I train, but it would be really nice if Stages had a way to input a manual offset like other power meters so I could get the two to match perfectly.

Otherwise, this meter is rock solid. The gen 3 Stages stuff really is a lot better than the previous generations. If you're running stock Cannondale cranks and need a solid, reliable PM for a good price, it's hard to beat this one.

While I dont yet have a lot of timemiles in using the power meter, its been a fabulous tool to kick-start my spring training. Its good to be able to quantify the effort relative to heart rate.

Quick and cheap way to get power data on my cannondale mountain bike. I've taken it through mud and got caught in the rain and so far the stages power meter hasn't been affected. Hopefully the weather seal issues I've read about in the past have been resolved. So far so good.

excellent products and LBS installed within 2 days. Nice to have true power readings rather than just Garmin computer estimates.
