powertap sl got it off ebay a month ago.
started using it this week no problems so far
today i started my ride and noticed there where some low numbers in the wattage section of the display slowly changing by one or two. the hr wasnt being picked up and neither was my cadence. tried holding down buttons to make it "find" and tried clearing the data but to no avail.
any help or tips?
today was a critical ride for my coach and i couldn't get the pt to work for the life of me!
also some other questions:
how do you reset it so the timer starts fresh? with milage and stuff?
