Santana : Titanium Tandem Bike

Since everyone knows about titanium, we’ll keep this short. The other guys mix two butted seat tubes with a bunch of seamed 6/4 plain gauge pipe and a teensy pair of single bike chainstays to create a heavier tandem that looks better than it rides. Santana is the only builder using seamless custom-drawn tandem-specific tubing. (We take as much care with our tandems as they do with their singles.)

• Stiffer, lighter 

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?

features a conically-tapered downtube.
• Breaks the 7-pound barrier — lighter than traditional carbon frames.

Elite Components 

• Shimano’s XT rear derailleur is lighter, stronger, and handles a wider range of ratios than the Deore or Ultegra changers found on other tandems
• Hardcore Carbon Octalink crankset is mounted to a tandem version of Shimano’s pipe-splined bottom brackets for reduced weight and improved power
• Triple pinned-and-ramped chainrings with a larger outer ring are hard anodized to speed shifts and reduce wear
• 32° Pillar PSR Quadro Butted 700c

• Hadley Racing’s tandem hubs with titanium skewers are, quite simply, the world’s lightest, strongest and most reliable
• Deep-section tandem rims with double-eyelet reinforcement and machined braking surfaces
