Power meter crank
Easy purchase. Delivery was great. Slight delay due to weather. Package arrived intact. All parts as stated. Installation was very easy. Replaced my shimano 105 crank off my Trek Emonda ALR5. Now I have a power meter. Calibrate prior to each use. No issues yet. Enjoying it.
Quick delivery, good pricing! Got the LBS to install (along with new 105 R7000 derailleurs). Love the overall look of the chainrings, cranks and the integration of the power meter. Easy to calibrate with 4iiii app, and it synced immediately with Wahoo Elemnt Bolt. Really useful to get some insight on my power numbers after the first few rides. Very happy with this product!
4i dual sided power meter
Arrived in less than 24 hours from order, fitted in five minutes. On my first ride it wouldn't give left right balance, checked batteries a one was dead. Battery replaced and works a dream. It replaced my old 6800 ultegra as it developed a creak and for the price it was a steal. Its just a good as the ultegra but a few grams more. Only 4 stars due to the flat battery
