Too bad you don't have that PT still. Grabbing the power measurements is a sure way to see how it all pans out.
Very good call. The Tri guy just left the shop a bit ago in a snowstorm to run home and jump on his computrainer..
2 other guys with PT wheels both ordered the rings form me this week.
If they see a 1 watt increase they will shit themselves for sure.
I bet they see at least a 5 watt total power output increase.. maybe more.
The clinical study on the Rotor site shows a average 3% gain in a small test group.
My buddy Don c. was putting out over 400 watts on these the other day. Don could be my dad. He has silver hair and he could kick my ass.. except on a mt bike as long as the trail keeps twisting. Maybe.
