Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Powertap hub offset is -1

Hey,

I have a powertap g3 hub, it has recently been giving low readings at times, it may start out reading my power correctly, but then start drifting down. I calibrated it on the Garmin 520 and it always reads -1 ,

I still have a joule gps and used that today and it showed the offset at -1, Is this the new readings? I thought it was supposed to be around 512?
I'm hoping it's just the end cap causing a problem and not the hub itself, it's about 3 years old.

Anyone had similar issues or readings? thanks.

Yeah, I'll do that on Monday. I'm in Ireland though, their service reps here are terrible-paligap-actually less than useless. Even when I bought the hub a few years ago, I bought from the American site because the customer service is so much better.
It will be Monday evening over here before I get a hold of them-I was hoping someone here had a similar issue-thanks though....

Powertap changed the base for the offset values.

The target is zero, plus or minus thirty.

Therefore -30 to 30 is good.

Thanks a lot lads, it's weird, I went out this morning, and it was working fine again. I had removed the battery and left it overnight, and then replaces it. It read on the Garmin that it was 'pairing' again or something flashed quickly. Of course we had a fluctuation of 15 degrees in temperature here last week, so that may have had a part to play as well as me 'calibrating' every five minutes lol.
