I see a lot of threads saying how GPS can have as much as 20% inaccuracy in mileage with trails with lots of elevation changes and turns.
My goal is to basically track current speed, average speed, top speed, current distance (current ride), and cumulative distance (from all rides). I'd also like to know my average pedal speed. Seems like the CC-RD430DW or CC-RD400DW should be able to do this. The only thing it lacks is monitoring altitude which I don't think will be of importance to me.
Some nice additions to have would be ability to sync via BT to my iphone to upload data and outside temperature, but not really required.
I see the Garmin 510 does a lot, but i'm hesistant to pay $400 when there's other models for less than half the price that seem to do the same.
Do any Garmin's tie into the wheel to offer more precise distance measurement? Do the Cateyes provide more accurate distance being tied to the wheel?
Thanks for your help
