| Jul 18, 2012 at 15:02 | comment | added | amcnabb | Those are good points. | |
| Jul 18, 2012 at 15:01 | comment | added | Stephen Touset | You only need to measure the road grade once. And it's probably more accurate than a GPS device for shorter hills. You'd probably need to stop to get a reasonable readout from the inclinometer anyway. | |
