I have really taken a hiatus from cycling minus the mt biking I do 1 x a week and the power crank rides that vary. I startedbuilding my cycling back in this week and decided to run my first 20 min LT field test this a.m. While I am down over 30% since August I was fairly happy with 250 watts. last year I had been riding for 2 moths before my jan LT test and only averaged 25 more watts. I know that after 4 months of not riding only the powercranks could have helped this much!
