Dario Pegoretti Q&A

[BroDeal]

Richard Sachs got Dario to post in the "smoked out" section of Velocipede Salon. He is answering questions.

The initial part of Dario's interaction is at the tail end of the Pegoretti gallery thread.

thanks for the link! Interesting stuff...and Dario gives about a clear an answer why frame weight isn' t really important as I have ever heard:



"I think even the lightweight carbon fibre frames (800/900grammi)not offer performance comparable to frames built with the same material a bitmore heavy, I think it was mainly the marketing to push the construction of frames very light than a real need.
What I tried to do was to research the best possible efficiency of the frame.
We must think of having to move a mass from a to b, but the mass is the bike and rider and the bike is about 10% of the total mass, the frame around 2% of the total mass.
I think have not a great sense to try and save 20/30% of 2% If this causes a loss of a part of the power that we put on the pedal for 70/90 times per minute."

yeah but companies love selling the idea of 'new technology' as the suckers fall head over heels for it and he mark up is huge.

I would love to see someone ride a steel frame again in the pro peloton to dismiss the idea that carbon is better. Maybe Paris Roubaix.

God I want one!!

Interestingly though Benotti, Colnago said that it wasn't until his frames had been ridden to 5 or so victories in Paris-Roubaix that carbon became accepted as a genuine material..

Mr. Merckx has said the same thing. You can objectively measure only 2 things in a bike shop, weight and price. Marketing run amok.

A light, 800 gram frame that costs $10,000 is light and expensive, not necessarily any good to ride.
