SOC16: Power measurement enters third dimension with new 4iiii Precision 2.0 meter (Bike Rumour)
Introduced at Interbike 2014, the 4iiii power meter has come a long way very quickly. Originally planned as a DIY add on, they showed an even smaller unit at Sea Otter last year and introduced their factory installation option. Now, they’ve done away with the end user installation option and are offering two ways to get their power meter on your bike, both still starting under $400.
