@hippy does this assuage your subcompact power meter woes?
This was one of the big pieces of feedback that came from my review of Easton’s super-compact double rings on my EC90 SL cranks last year: people loved the idea of the 46/30 ring combo, the adaptability of the Cinch system, and the option to add a spindle-based power meter – but the price of the carbon crank arms was somewhat prohibitive.
So here’s the deal. EA90 crank arms will run you a cool $120 USD, in comparison to $400 for the EC90 SL arms. You still have to buy a bottom bracket for $50 and choose a chainring setup ($80 for a single ring or $150 for a double).
Yeah would be ok if they do short crank lengths. I've just bought a Quarq and will run a big cassette this year. I'll deal with the bigger gaps between gears.
