Very nice kit

I bought this in the probike sale and also got a discount code after a google search. It’s an excellent product. I only really needed a compact chain set but decided I may as well get the power meter attached. I had some self inflicted setup issues but 4iiii were so helpful and quick to respond (5 minutes after contacting) that I got this up and running very quickly. The power meter is accurate giving me a slightly higher wattage output than my Suito turbo which you’d expect in that there is no wattage loss through the drive chain. Overall I’m really pleased with the product.

Loving data

This is the first time using a power meter and I am loving it. The connection is so reliable and the bonus is the cadence measuring capability. Fits my Emonda dura ace as they were made for each other.
