I wanted to post a follow-up to my order and use thus far. My order was shipped in a very timely fashion and I received it in about five days (Canada to US). I ordered the Rotor 3D+ with Praxis rings and I am very pleased with the fit and finish of both and the performance of the power meter. My use thus far has only been indoors with TrainerRoad and it has worked quite well and proven to be very dependable.
I am very pleased with the overall transaction, product experience, and support you provide here on Slowtwitch. The Rotor crank is a very nice upgrade for my bike and coupled with the Power2Max, I think it's a great value.
