It tough to go wrong with the Assioma Duo pedals. Those are one of the few products that few people say anything negative about. They just work and the price is fantastic.

There is a recent emergence of questionable performance from crank arm-based PMs that use Shimano cranks. So, that is one thing to put in the back of your mind.

The crank-based PMs are very good and provide accurate total power. But, they only have estimates for L/R power.

If you want true L/R power, then get the Assiomas. If L/R estimates are good enough, then add the crank power meters to the list.
