Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

200 lib rider + 20 lb bike -> 15.5 mph

Can someone please just throw 10lbs of pork chops into their cute little spandex shorts on their next trip? Make sure you insert your Garmin into your corn hole and record all your data. Then, next week on your next ride of course, complete the journey again and report all data back to the forum.

But it it will be totally meaningless. Early on a polite an inteligent man dropped some knowledge that can’t be measured but will surely have the greatest impact. It’s the fact that the weight is coming of your person, your heart will not be working as hard to pump blood to a smaller body.

now to really blow your minds. It’s not that I can’t ride all over and I end up having to walk my bike up hills, how that got blown up is beyond me.

didnt it occur to any of you that I may actually be more efficient oxygen wise in a higher gear? No one mentioned this and I had a chat today and did some research. Different bodies work in different ways. Mashing vs spinning, fast twitch/slow twitch anaerobic vs aerobic.

But I believe I have all the info I need, thanks for the entertainment.

Statistics tells us that you’re far more likely to be wrong than that you’re some sort of genetic freak that excels at low cadence cycling relative to the rest of the world.

Psychology tells us you should probably work on your attitude.

Does this mean that a 200 lb rider that averages 16mph over a 30 mile flat course will average 20mph over the exact same course if he does nothing other than lose 48 lbs?

Ahh, that lower cadence leads to better oxygen efficiency has been known for a long time (and is well documented). There are drawbacks to it and good reasons road racers ride the high cadences but those don't change the fact of low cadence-higher oxygen efficiency.

And re: this forum - most of the time I don't post here because of exactly the attitudes seen in this thread. But I am a pure roadie. Always have been. And I have done over half my road miles on fix gears. Balancing the gear for uphill vs flat vs downhill is a very real part of road riding fixed, (Or stopping and letting your body cool down, change the gear, then have to warm up again.) It's a different game, but just as much "road riding" as what any of you "roadies" do.

Hard men ride fix gears., Don't believe me? Put in a 130 mile day fixed. Ride up and around Crater Lake. Ride the courses of the early Tour de Frances. Do it and come back to me.

I HAVE a fixed gear. And much/most of what you say is true. But it doest change the sillyness or bad attitude of the OP.
