Very impressed with this PM. I’ve been using crank based for close to a decade, but when I upgraded my bike, I decided to try a new system. Super easy to install. Great app used to keep firmware updated. Zero dropped connection on my first ride, which is a huge improvement! Would recommend every time.

Great product, fantastic price and ideal product to keep a super light race bike as it should be. Very consistent and minimalist. Just have to be careful of customs charge if buying from Europe!

I wanted a Power Meter, but I’m also on a budget. This product was by far the easiest upgrade I’ve ever done to my bike! Pulled the left crank-arm, put a new CR-2032 battery in, installed crank arm and pedal, updated firmware, calibrated and off and riding. Pairing to my cyclometer was simple and the output matches what I get on my trainer. Definitely a good investment for me and I will incorporate into my training plan!

Dollar for dollar, I think this is the best single-sided PM going for those on a budget. It’s been 100% reliable in all sorts of messy conditions and has proven to match up very well with power numbers from my Kickr. PM City shipping was super quick and pricing was very fair. Will be a repeat customer.

Hi Cendres. Thanks for the review! Not only are you getting accurate, consistent data…but you got a DURA-ACE 9100 crank arm to boot – not too shabby 🙂 We hope you continue to enjoy it.
