Sorry if this is a dumb question but I’ve been pondering it over the last few days. I have a Lynskey GR300 with GRX Di2, aluminum wheels, 700x48 Rene Herse tires, and a P2M power meter. I also recently got a Specialized Roubaix Expert with 50mm deep wheels, GP5000 TL, and a left side 4iiii power meter.
I compared both PM’s to my Kickr and scaled the 4iiii since it seems to be a bit high. Both PMs now read about 4% higher than my Kickr which makes sense given drive train losses. Given this, I’d assume the power readings are pretty comparable.
I know the Roubaix is significantly faster with the current setups, but it seems easier to ride if that makes any sense and I can’t figure it out. Positions are similar, though slightly lower/longer on the Roubaix. 200W on the Roubaix is easy while 200W on the Lynskey seems more challenging.
Is this all in my head? Maybe going slower for the same power affects this perception? The Lynskey has an 11-40 cassette so maybe the bigger jumps are affecting my cadence more than I thought. I’m going to scrub and re-lube both chains to see if that helps.
