Strange wind readings after WET ride
Posted: Fri Feb 25, 2011 3:21 pm
Last night I rode home from work in the driving rain, this morning when I set out to go back to work the rain had stopped but the wind was at 20+mph from the NNW, even when I was pedaling as hard + fast as I could into the wind, my ground speed was barely in excess of 6-10mph when I was riding directly into the headwind and the dash *should have* been reading at least 250-400 watts, based on past feel. Instead the dash was reading a windspeed relative to the ground (not total) of -14.5 to -8.7 mph as though I had a healthy tailwind and power was reading 0-100 watts.
Prior to today, I had one other very wet ride home and during the rainy ride I'd noticed a slight tendency to treat a headwind as a tailwind, but that was a friday and I didn't ride on the weekend so the bike & iBike had plenty of time to dry out.
Any idea what might be going wrong? I'm always very careful to dry the exterior of the phone booth before taking my iPhone out -- is there anything else I should be careful to do to avoid this problem in future?
Thanks!
