Wahoo Element Bolt
 

I'm on the verge of ordering one of these. To the folks who use them a question please. I have a PowerTap C1 (Chainring) power meter, ideally these should be zero-offset before every ride. Does the Element Bolt have a menu item like the Garmin to do this? TIA.

It does and works for my Stages power meter. There is a “recalibrate” button under the settings/system menu. You can do it right on the head unit.

I think Wahoo offers a return period. Try it and see.

Excellent, many thanks much appreciated. I used to have a Polar m450 which had no such option it was an utter
PITA ;(

Here are the actual instructions on how it works and how you do it. You power meter needs to support the power meter profile under BTLE and/or ANT+. Fortunately virtually every current device does.

Excellent , I'll go and order at my LBS this weekend. Thanks.

I use mine to zero-offset my Assioma pedals. It's worked every time.
