Hey Patrick, listened to your advice and ended up with Power2Max 🙂 costed me a foftune though as i opted not to down grade from my Campagnolo! Missed the chance to have it on for this weekend ride so first trial would be next Tuesday:) just wondering how can I set my crank length in my Garmin 800, doesnt seem they have allowed for it for third party power meters!!! Google search doesnt bring up much unfortunately, apparently with vector PMs with the first pairing crank length appears in the bike set up and can be altered. Any idea?
