2015 Cannondale F-Si Hardtail Adds Playfulness to XC Racing


2015 Cannondale F-Si Carbon Team

Most World Cup XC hardtails are built for the ultimate in speed and efficiency. Mere mortals will gladly pedal one uphill, but get pretty beat up on the downhill. Sadly, not everyone can be Nino Schurter, or in this case, Peter Sagan.

When the 2015 Cannondale F-Si was introduced, current 3-time Tour de France overall points classification winner, Peter Sagan, took one out for a trail ride with Marco Fontana and they had a pretty darn good time.

F-Si System 29 Integration

Making a World Cup hardtail playful and fun seems borderline anathema, but Cannondale didn’t care. The complete System 29 integration eschews many things that are staples of racing frames For example:

  1. Super-short 429mm (16.9 in) chainstays
  2. Custom, 55mm offset Lefty fork
  3. 69.5 degree head angle (very slack for a 29er)
  4. Ai Drivetrain offsets the rear hub asymmetrically
  5. SAVE 2 carbon seatpost increase deflection by 20%

The overall result of the Ai Drivetrain promises nimble and fun handling without sacrificing climbing or race-course performance. Check out Cannondale’s lead engineer explain in plain terms why the all-new 2015 F-Si is so special.

F-Si is Worth Getting Stoked About

Admittedly, it’s hard to get really, really stoked on a 29er hardtail. They are purpose-built sleds that are made for 20-something’s who can take the abuse. But, the F-Si is different. The promise of nimble handling that’s stable enough for today’s technical downhill sections has me sitting up straight and paying attention. This bike may just be something special.
