NACA designed tubes

Triathlon Forum

Are there any other bike frames besides Cervelo that use NACA (National Advisory Committee for Aeronautics) designed tubes?

Cervelo no long uses NACA tubes (I believe they moved on when they went to Smartwall2)
Companies I’ve seen reference NACA tube shapes:

  1. Jamis
  2. Parlee
  3. Specialized
  4. Felt? I’m not sure.

No-mo for Cervelo?! Hmm. I didn’t know that. Thanks.
