This talk might well be very interesting. Santana has been accumulating data on tandem frame stiffness and weight. Upon completion of our Calfee's maiden ride in 2010 we took it to the Santana booth at Solvang, and it was evaluated as part of this program. TG discussed this program in, as is his wont, exhaustive detail.


Frame stiffness rig


Boom tube deflection 14.03 mm


Weigh in


Ours was 25.15 lbs (the lightest they had yet recorded, btw )


Data on multiple tandems compiled


Lots of data here!

As far as I know, the findings of this project have never been disclosed. A Google search turns up only what has been discussed here on BF. This talk is an opportunity for these interesting data to be presented and discussed. This talk isn't just anywhere, it is in Cupertino, in Silicon Valley, e.g., a mere 1.2 miles from Apple Headquarters. There will be no particular shortage of scientists and engineers at the event, and thus a perfect opportunity to present the data to a eager and inquisitive audience.

Findings that might be interesting:

• What frame material proved the lightest?
• Was there any relationship between frame material and deflection?
• Did lateral tubes reduce frame deflection?
• Did lighter tandems have more frame deflection?
