Mainly for tarmac, must have Speed, Cadence, Heart Rate. Altitude (distance climbed/descended) would be nice. Not that fussed for GPS mapping.
Contenders but not limited too
Cateye V3
Sigma 2209
Garmin 200/500 (getting a little expensive really)
Bryton??
Whats your recommendations, these things aint cheap so want some direction.
