The Lefty has been around for well over a decade, and I'd argue (and have argued) that the single-sided fork, with its square stanchion tube and roller bearing strips, makes a lot more sense than using silly fork bushings and depending on arches and axles to keep things pointing in the same direction. One capable of the increasingly rough courses at on World Cup circuit. Might as well start with the digits that you're probably most interested in: Cannondale claims that the 2017 Scalpel-Si Hi-MOD frame (the fanciest version) weighs just … Sealed bearings are employed all around, besides at the Flexstay, for obvious reasons, and I was told that the bike's designers put an emphasis on making the pivots easy to work on. Speaking of weight, Cannondale says that the bike's injection molded carbon rocker link saves even more weight over an aluminum rocker. Cannondale claims that the design, which they've been using for years now, does everything that Boost accomplishes and more, including making for a compact rear-end without compromising tire clearance (there's a ton of it) or the ability to run two chainrings. Too much tech info, not enough riding info, so let's move on to what matters. Asymmetric Integration, or Ai for short, is new to the Scalpel but first used on Cannondale's F-SI race hardtails. Would you? Photo: Cannondale. So instead, Cannondale sent a $4,499 USD Scalpel-Si Carbon 3 my way so I could put some miles in on trails that I'm extremely acquainted with. The latter has become the norm, however, and anything that's visually different seems to freak people out. Introduced at the Riva del Garda Mountain Bike Festival, the all-new 2017 Cannondale Scalpel Si goes further than ever down the “Systems Integration” path to become a far more capable XC race bike. Why? Because riding a new bike on unfamiliar terrain isn't usually the best way to see how it handles. The gist is that the new Scalpel-Si and its 'OutFront' geometry is longer and slacker than the old bike, and is also slacker and has more fork offset than its most important competition, which is why Cannondale stuck that extra X in front of XC. It sees the normal 12 x 142mm hub and drivetrain shifted to the right by 6mm, along with equal spoke tension and angles for the rear wheel. Cannondale doesn't seem to give a shit, which I admire, and it doesn't hurt that the Lefty's fork chassis is also functionally awesome. Also, I live in southwestern British Columbia, halfway between Kamloops and Whistler, and I'd rather not leave. This carbon link is used on all of the bikes, including the $2,999 USD aluminum Scalpel Si-5. Then, the crank's spider moves the chainring 6mm to the right to compensate.

There are probably some more important numbers than weight, however, especially for those who don't own a bunch of white Lycra shorts or a year's supply of Breathe Right strips: geometry. The aluminum ScalpeI-Si AL 5 costs $3,200 USD, or one quarter of the price of the Black Inc model.
