1993 GT Quatrefoil
The 1993 Quatrefoil designed for years a fast moving tandem fun.
Description
The 1993 GT Quatrefoil is a chromoly tandem mountain bike built around a TIG pulse-welded Tange double-butted frame with GT’s Triple Triangle design, sized in paired configurations to accommodate riders of different proportions. The GT Unicrown fork features 1-1/8″ oversize butted chromoly blades and a matching oversize steerer, paired with a Tioga headset. Drivetrain duties fall to a Sugino GP tandem crankset with a 50/40/28 chainring combination driven through Shimano Altus A10 21-speed shifting. Araya TM-18 alloy 36-hole rims wrapped in 26×1.95 dual-purpose tires provide a capable contact patch for trail riding. Saddles and crank arms are anatomically sized for each position.
