I don't think that anyone is saying that there's zero difference, but people will call out extraordinary claims. Your claim of gaining a couple mph when in the 40 mph range falls in to the extraordinary range. With a combined bike and rider weight of 180 lbs, it'd take an additional ~300 watts or so from the rider to speed up a couple mph, assuming they were coasting at ~40, yet you say you've achieved those gains from the wheels alone. That's a lot of energy savings from a pair of wheels, everything else equal.
Ok wait...
if you guys are going to call BS on me...I'm going to call it on you.
first off...if you're going to sit there and tell me it takes 300 watts to speed up from 38mph to 40 while flying down a large, steep hill...I'm calling BS. Second...weight is not the only factor when it comes to required power. There are a ton of factors involved in determining how much power it takes to move mass...that 180 LBS you incorrectly estimated isn't floating you know...
I claim I was seeing an average increase of a couple of mph while coasting down a giant hill...and many of you call BS. Then then come on here and try to use some open ended math (math that is missing a ton a variables btw) and actually attempt to pass that off as some definitive logic?
"41" indeed...
