To make up for an almost total lack of weekend cycling I hit the turbo tonight after swapping cassettes and wheels on the Planet-X TT machine. I’ve now got the wireless Powertap on it.

The last attempt at a turbo session was dismal – failure to hold anywhere near 75% FTP – dropping to 50% for 10min. I have a feeling there’s actually something wrong with my Wired unit since this time I managed a 2 x 20min with relative ease. First 20min at .75FTP, 5min rest, second 20min at .80FTP with the last minute around 300W.. for fun.

The wired Powertap was out of action for ages with suspected water penetration due to a cracked cover. I swapped the cover for a new one but wonder if it’s possible that the new cover is on too tight or something?
