Subject: RE: power tap wheel optionsThe PT hub actually measures your speed and cadence...but at times can be unreliable...not sure how much so, but the fact that they sell the sensors makes me believe that it may be worth having. The speed and cadence sensor are sold separately. They are actually the same thing...so if you want speed and cadence, you need to get 2 of them. It can also be good if you plan to use other wheels with your bike. Because if you don't have the PT wheel on, you can still use the computer and the speed/cadence sensors. I believe the difference in the elite and the pro is mainly the weight. But I think the PT website also mentions that the Pro can do onboard analysis...whatever that means. |
