I haven't had to replace the hub batteries in my PowerTap SL yet, but I imagine I will soon. I've had the powermeter since late December, so probably put 150-200 hours on it.
The owner's manual lists Silver Oxide #357 batteries. I'm not familiar with these, and I haven't seen them in the stores. Any good places to find them?
I've also noticed that the heart rate function drops out fairly often for minutes at a time. I've replaced the 2032 battery twice. Is this function drop normal.
Otherwise, I think power training may help me improve my performance. I'll be 56 in April, and I currently weigh 68 kilograms. I raced last year for the first time in 20 years; I did okay, but I noticed that I lacked the "grunt" power that the best riders in my age class had (especially at Mt Evans in Colorado). This year I've worked my 30 minute lactate threshold average up from 259 to ~275 in the past three weeks. I haven't tried 2x20 or 2xanything yet. I've also started getting some online coaching from John Verheul in Santa Fe, NM. I've seen his name in this forum, and I believe he can help me to structure and discipline my training more than I have in the past.
I'd like to hear from other riders in my age group. Have you seen benefits from power training?
