Cycling Weekly Verdict

Shimano's first crack at a power meter with the R9100-P is by no means an immediate market leader, but the Japanese giant has delivered a reliable and easy to use dual-sided meter that looks the business. It has its issues, which could be rectified through updates. But for such a high price, it's worth considering if other options might suit your needs and save you some cash too.
