Advice From Our Staff:
This is one of those power meters that’s easy to get excited about. Admittedly, it’s only compatible with ROTOR KAPIC cranksets, but it measures power from both legs, is affordable, lightweight, accurate and works with both round and oval chainrings in sizes as small as 30T. There’s not much more to wish for than that. In fact, even if you don’t have a KAPIC crankset, you can order the power meter with cranks and a chainring for as little as $899. That’s a pretty good deal for a dual-sided power meter crankset!
