Shimano recently unveiled its new XT and Deore level Di2 drivetrains, marking another step forward in mountain bike technology. During a press camp in February, the new Shimano XTR Di2 components were showcased, and among the highlights was a retro Cannondale EST frame, a nostalgic nod to the evolution of mountain biking. The Cannondale EST, or Elevated Suspension Technology, was a groundbreaking design in its time, featuring an independent rear triangle with a shock absorber-dampened swingarm to improve speed and control on rough trails.
The EST frame’s rear triangle pivots vertically, with a hinge at the chainstay-seat tube junction and a spring-supported, oil-filled shock absorber connecting the swingarm to the main triangle. This design absorbs bumps and ruts, allowing riders to focus on speed rather than bike handling. The shock absorber is adjustable to match the rider’s weight, ensuring optimal performance across all terrains. Additionally, the frame includes Cannondale’s innovative “Force 40” braking system, which increases braking power by 40% compared to traditional cantilevers.
The EST frame, weighing under six pounds, was available in three sizes, with shock springs tailored to the typical rider weight for each size. It was paired with a Cannondale Pepperoni aluminum fork and a Girvin Lightweight Flexstem for front-wheel suspension. The bike’s componentry included high-quality parts like Shimano Deore XT drivetrain, Ritchey cranks, Easton Hyperlite handlebars, and Ringle Cam-twist seatpost quick releases.
The retro Cannondale EST serves as a reminder of how far mountain bike technology has come. While modern designs like Shimano’s Di2 drivetrains continue to push the boundaries of performance, the EST remains a testament to the innovative spirit that has driven the evolution of cycling. For enthusiasts, this glimpse into the past is a celebration of the creativity and engineering that have shaped the sport.
