GPS Bike Computer

c.p.w.g.w · 2018-11-06 15:06:18

So looking to get a proper bike computer. Ideally a GPS one. I'm just wondering what is needed with regards sensors. I assume the fact it'll be GPS speed sensor isn't needed. But with Cadence, how will that work, as i'm planning on getting a crack-arm power meter. Was looking at the Garmin Edge 520, on Wiggle for €180

Crank Power Meters generally provide cadence info. No need for a separate sensor.

Speed sensors aren't needed, but are more accurate, and work without (or with limited) GPS coverage (such as under trees/ tunnels).
