This is a Bryton heart rate monitor. I purchased it new from a Giant store about two years ago and used it a few times. I haven't used it recently, so I'm selling it. The items for sale are all shown in the first photo (heart rate monitor body, instruction manual, new battery). Please refrain from purchasing if you are looking for a pristine item, as this is a used product. To reduce shipping costs, I will fold and compress it for shipping. - Brand: Bryton - Model: Heart Rate Monitor - Accessories: Instruction manual, CR2032 battery #giant #Bryton #cyclecomputercompatible #heartratemonitor #heartrate #roadbike #MTB #criterium #enduro #cycling #hillclimb
