Been using a PowerCal HR-based power meter for a year or so, but I just don't believe it. I think it is calibrated for someone weighing 100# less than me (280).
I was about to plunk down $700 for the Stages crank-based power meter but then realized I'd be locked into a particular crankset going forward. Then I saw that for an extra $50 I can get a PowerTap-hub wheel:
I sort of need a stronger rear wheel anyway, have broken a spoke and also cracked the rim on my Domane (under warranty, thankfully).
Only thing I'm wondering is which rim to go with. They say a DT Swiss 465 is plenty strong, but the 585 looks more like the famed Deep V (which they also have, for another $200 - not on special).
They also have the Velocity family, including one of the Off-Center rims (A23) that Peter White says helps to reduce the dish and make the wheel stronger. Also for another $200.
Thoughts? I'm inclined to do the DT 585 rather than spring an extra $200 for a velocity rim. Had a Velocity Dyad wheel anyway and it wasn't great.
