SRM 7950 Compact Double Power Meter Crankset With 50 X 34 Chainrings

SRM has announced its SRM PowerMeter DuraAce 7950 compatible crankset, with 50 X 34 chainrings — a compact double favored by anyone facing steep climbs. See my analysis of gear ratios.

I’ve been promised a crankset for review, which I’ll install on my 2nd (black) Trek Madone 6.9 SSL (I currently have the SRM 7900 standard installed on my white Trek Madone 6.9 SSL).

Every ride, I rely on the SRM power meter and head unit for strictly objective feedback on my wattage, energy consumption, speed, distance, etc. I get objective evidence of improvement, as well as knowing exactly how much I’ve exerted myself. I would not want to ride without a power meter, as I consider the training feedback valuable both during the ride, and later, for analysis over time.
