Going out on a limb here but... Does anyone know if the new Mavic Win-Tech HR will read the Polar Heart strap? Both models look exactly the same. I wouldn't be surprised if Mavic Licensed the tech from Polar.
(before anyone asks the question why? - the s720i doesn't do current trip distance and my Cateye Double Wireless Cadence is crapping out on me - so I figured the Mavic might be the go - and if I can use one heart strap for 2 computers - even better).
