Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Edge 305 or Rox 9.0?

Just got through stringing the ugly black wires of my Strada Cadence all over my lovely white CAAD9 frame. I had been toying with the idea of something different in the computer area...specifically something wireless and that tracked altitude, climb, grade, etc. I've read ad nauseum all the stuff here about the Edge 305, nice unit no doubt, rock solid. The ROX 9.0 is a lot newer with fewer reports but what is there seems to be very positive.

Anyone out there used both and have something to say comparing the two? Thanks.

Hey, I hope you get some replies.

I must have read every post regd these two, had decided on the Rox but just a couple of days back changed to the 305. I think the screen is bigger and the GPS may be of a bit of use. Earlier I had discounted the requirement for GPS.

I really would like to know which is better/more accurate for altitude/grade etc. I think the Rox has a calibratable barometer?

Can you mark out laps in the Rox? I know in the Garmin you can push a button every time you want a new lap to begin?

Plus I like the odo on the Rox. Nothing like that on the 305.

The barometer will be more accurate than plain old GPS altitude. If you have a GPS that can take advantage of WAAS then the altitude will be just as good if not better from the GPS unit. Unfortunately, none of the Garmin Edge units can receive WAAS.

More accurate, still, is the Gravity service from Motionbased. (and I'm sure other sites/programs have something similar) It uses known elevation data and figures your altitude based on your horizontal position. Combine that with a 305 or 705, which have barometers, and you'll have spot-on altitude.

I'd go with the Garmin for the GPS. It does everything any other computer does with the added benefit of GPS. It lets you do some cool things with analyzing your ride, planning out routes, etc.
