Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Sigma 26.13 STS vs Powermeter

Hello, I was looking at bycicle computers and then I saw the Sigma 26.13 for around 100 euros and it says it shows power in Watts.

Does anyone know how this works ? It knows the speed and cadence and works out the Watts this way, even without knowning the wind or the slope ?

I obviously know the precision on this thing will be terrible, but is there a way to know how the precision is going to be ? thanks

Is it the 23.16 (not 26.13)?

Yeah, they don't say much about the calculated power. It can't be accurate.
It only has wheel speed, cadence and heart rate sensors.

Just write 300w on a piece of paper and tape it to your stem. It'll be just as accurate, and a lot cheaper.

Would you pay $100 for Strava's power estimates?
