this be a great bicycle computer for road bike training and general ride . have many parameter it monitor in real time . I especially like the heart rate monitor function -lrb- current hr , hr Zone , HR Alarms , and more -rrb- , plus all the usual bicycle paramter such as speed and cadence include each of they varient . but my favorite be all the gp function -lrb- include upload you ride route to Garmin Training Center software and\/or to MapMyRide.com -rrb- and I really like the % Grade , Elevation , and climb paramter . Works very well here in the foothill of Boulder Colorado area . highly RECOMENDED !!!!!
