Today, I received my USA-based trainer from manufacturer CycleOps and I am seriously happy.
I chose this trainer because of the quality of the products that CycleOps/PowerTap make and considering that they also made the first and only hub based power meter I think this makes them overly qualified to ship the best direct-drive controlled trainer on the market.
Details are that the power accuracy is +/- 3% with the Hammer handling up to 2,000 watts at 20 mph and simulate grades up to 20%.
My absolute favorite part of the CycleOps Hammer is the 20lbs flywheel-based direct-drive trainer feel. It’s near silence and outside like feel makes this setup the perfect Zwifting tool.
