I bought a wired PT several years ago and have had to replace the wiring harness once. I have also bought a second wiring harness for my TT bike. I should have just bought the wireless one although as I recall back then the price differential was much larger than it is now.

In many ways, a PT is more valuable indoors than it is outdoors because you eliminate most of the other variables (traffic, wind, downhills in the wrong places, etc.). I got home late tonight and did a quick 30 min Spinervals Time Saver workout - 7 x 90 second intervals with the PT (perfect winter workout for after work).

My best winter routine is the 2 month CTS Progressive Power DVD Series - an 8 week power based training program. It is a little expensive but well worth it for me to keep my interest in the winter (Wisconsin).
