Here's a really specific question, but what the heck. I'm supposed to pick up a powertap wheel which originally had the comp hub but was upgraded to G3 last year. I'm interested in getting the Bluetooth cap for it as its only $50 on their site now. According to the description it says upgraded pro and elite models can accept the cap but i was wondering if essentially any model with the new cap can accept the Bluetooth. I sent an email to saris but figured I'd ask here anyway!
