1 review for power2max NG ROTOR ALDHU Road Power Meter Crankset
  1. Glen (verified owner)

    There are plenty of places to go for reviews about how well these P2M NG and NGeco power meters work so I won’t repeat all that. I’ve had an NGeco for a while now, and that’s part of why I went with this one. They just work, and the Rotor ALDHU cranks are well made, easier to install than just about anything else out right now and available with 24 or 30mm spindles.

    Pulled my Shimano crankset and this slid easily into place. There’s a quick youtube video from P2M covering this and showing just how easy it is. Just slightly out of date but nothing significant, the Rotor cranks now say 35nm vice the 40nm in the video. And the preload collar now takes a 2mm vice the 2.5mm used in the video, or vice versa, I’ve already forgotten.

    Power Meter City as always provided great customer service through good communication, quick order processing and handling. I’ve done business here before and will continue to do so as power meter are a not insignificant investment and it helps to buy from someone with good service.
