TITANIUM FRAME NOTES

Other builders combine standard single bike tubes (including a teensy pair of chainstays) with impressive looking down tube and bottom tubes made from heavier industrial pipe. The resulting titanium tandem frame weighs more than Santana's aluminum frames. Additionally, due to the unfortunate combination of a round bottom tube and undersized chainstays, these frames lack drivetrain stiffness and efficiency, a performance handicap that becomes obvious during out-of-saddle sprints and climbs. Finally, the use of relatively heavy gauges negate titanium's famous comfort.

Santana is the only builder using a custom-drawn tandem-specific titanium tubeset. While it is often hard to spot differences in tubing, here are three places—all exclusive to Santana—where a visual inspection will verify the superior performance of our titanium frames.

• Oversize taper-diameter stays are properly ovalized for tire and chain clearance.
• The world's only oversize taper-diameter titanium downtube.
• A bottom tube that is larger and properly ovalized.

Why settle for 30% less when Santana's titanium tandem frame is a Ten?
