Excellent value for money entry into power. Having used crank based powermeters in the past I found this gave very comparable results.
As usuall great service from merlin cycles. It's the first time that I have used a power meter, so far the stages has performed flawlessly , I calibrate it before every ride which is very easy to do using my garmin 501. Only problem is , is that it has proved how much more work I need to do on my fitness.
Excellent, easy to install and only 16g heavier than the ULTEGRA 6700 crank arm that it replaces - so, if you're wondering whether to spend the extra on the Ultegra version, you may want to consider this. I'm also very happy with the results - they track almost identically with those from my calibrated Tacx Fortius and I see no drift in my L/R balance over 160k rides.
