Crabon bikes are fast!

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

Crabon bikes are fast!

Steel looks/feels better.

steel frames look better because they express the essence of eloquent simplicity that the bicycle is. Steel also absorbs road shock is more comfortable to ride.

I think it must just be "cool" in certain circles to be different from everyone else and use a word like crabon instead of carbon like most people use.

I can tell from your post count and join date that you are new. It's a running joke. Same with "drope the hamer", "guads", and "assplode" (which is what crabon frames often do). You shouldn't always take this place too seriously.

Interesting. I find that it grossly underestimates elevation gains around me(rolling farmland and whatnot). My GPS unit, that counts the elevation change as I ride, is consistently 30% more than what Strava shows. Each time my GPS auto uploads to Strava, I try to guess how far off they are from one another.
In the end, it isnt really important. Just funny.

That may be your opinion, which has absolutely nothing to do with the true fact of this thread.

That fact? Crabon bikes are fast.

The only elevation I get is the countless speed bumps, and I can get over 200 meters elevation gain on a 24 km out and back.

I thought that assplosions were from eating too much at charity ride rest stops?

Today, I took out my crabon bike out for a spin, after a year laying dormant. Focus Cayo, Force groupset, Psimet crabon tubulars. I followed the same route I rode on my trusty steelstead last week and lo and behold, I went over 2 mph faster on the crabon bike!

For the nonbelievers, I shall present evidence.

Exhibit 1, ride on the steel bike:



Note the average speed (shall not be confused with cruising speed.)

Exhibit 2, same ride on the crabon bike:



That's like a 15% gain in speed!

So, is crabon faster? Discuss.
Do not rule out the effect that you KNEW you were riding on a carbon bike. This is the reason for "double blind" tests; Everything disguised, you don't know what bike you are riding on, anyone administering the test does not know what bike you are riding on. Now bikes are difficult to disguise without messing up the aerodynamics. But you cannot discount placebo effects.

Now lets talk physics. Moving a weight W over a height H + distance D in time T requires 'X' energy

Using X energy to move weight W-Z over height H + distance D will result in < T.

We didn't talk about what was in your water bottles.

What if placebo was in one & plain water in the other? You can't always taste the difference, right?

sounds like you need to retest this bike experiment a number of times and average them out, conclude that steel is really slow but saves power
