I've just had a Hammer as an early christmas present to me ;) and i'm a bit underwhelmed with how long its power readings take to come into line compared to my p2max's.
Firmware is all upto date.
No dropouts occurring to screw readings.
If i perform a spindown in either rouvy or trainerroad as well as doing the p2m via my garmin, before starting, and then again as it warms up ~10-15mins in, i'm getting the hammer overread by about 35-40w at a displayed wattage from the p2m of 180-220w depending on what i'm doing, and sweetspot hr a good 15bpm lower than what i'm used to.
It's taking repeated spindowns during a 1hr session before it tracks pretty closely (30-40 mins in).
I expect a bit of difference, but to overead by such a high percentage, compared to a spider based system with q-rings, is effectively trashing the first half of my workouts.
It made me question the p2m i was using, but i changed bikes to a different p2m, and results are the same. Both P2m's track to an acceptible level my G3 powertap.
Spindowns from ~21mph or whatever it is, down to zero are taking around 100 secs, but when the calibration pop up screen appears, it says 16ish, a good 30 secs after you have stopped pedalling.
Saris seem to think this is normal, is this what those using the hammer would expect?
Currently undecided whether to send it back :(
Thanks
Phil
