View Full Version : Powertap and speed

09-12-2009, 04:19 PM
Hi - my 310xt has paired successfully with my powertap hub. On my turbo the 310xt gives me a speed reading that presumably comes off the hub. When I'm on the road, does the speed reading still come from the hub, or does it come from the GPS (which I would prefer)? Not taken it onto the road yet - weather not too good! Cheers, Mark
