What is the difference between the smartwall tubing on the P2K and P3 and the smartwall2 tubing on the dual? Is the smartwall2 a new and enhanced version of Cervelo’s tubing? and if so why don’t the more expensive bikes use this technology?
Here’s the description on Cervelo’s website:
The new Smartwall 2™ builds on the original Smartwall downtube with a new bulge-butted seat tube and a tapered & ovalized top tube. The butting and shaping of the chain stays is also new. The new dropouts provide improved strength, reduced weight and easier wheel changes.
This question looks like something only Gerard can really answer.
