Subject: RE: Changing from HR to Power what do I need? you need a power meter. since you probably like your FLOs- then don't get a 'hub' based Powertap. You can choose between a Crank, Chainring or Pedal based power meter. If I were shopping today, and not wanting to spend a ton of money but wanted a good power meter- I'd probably look at the Power2Max chainring based units- as they're lowering their price. If I were switching bikes a lot, and wanted to be able to use my FLOs on a road and tri bike, then I'd probably spring for the Pedal based system. Powertap's P1 is the slickest. And then.... you want some way to start interpreting the data. Training Peaks, Golden Cheetah, Strava Premium- or I just found "Endurance Tracker" which is free and seems fairly slick. Your 910xt is totally power meter capable. you don't "NEED" anything else as far as instruments go. However, it's kinda' nice to have a dedicated bike computer mounted right in front of you, rather than on your wrist. you may want to pick up a garmin Edge500 as a great basic computer, or a 510, 520. all good. The Polar m450 is cheaper and will pick up power, but I'm not sure it calculates the Np, IF, RSS values (you'll learn about them) that you might want. My only complaint with the Edge 500 is that the GPS lock is kinda' slow. Sometimes I wait for a minute or two. and the navigation is limited to a breadcrumb trail and the firmware is kinda' iffy on that. the breadcrumb blinks out sometimes. |
