Comments about Sigma Sport Sigma Rox 8.1 Wireless Cycling Computer:
Cadence sensor is a bit bulky. Cadence is also likely to be intermittant near power lines. Heartrate and speed do not seem to be affected.
Only 3 heart rate zones. All the heartrate, altitude, power and cadence data calculated is really cool. Gives one a really good history of the ride.
