Got myself a Speed Cage 11:15 derraileur pulley system. Not sure how this N=1 experiment will go, but I’ll take any placebo effect any day.
The pulley rotates for a long time. I know it’s marketing, and it took probably less than 0.001w of power to flick that pulley around, negligible effort for my legs. But then again, in all honesty, I need a new toy to keep me happy and excited about my bike. But if it does truly ease some wattage on my legs, I’ll take it any day.
“Work on the engine” is what I would say to myself. Who cares?!
Post ride: the turn of the pedal is butter smooth. Placebo or not, it just feels smoother. It’s like pedaling my single speed — no additional resistance from additional pulleys. It’s a keeper.
