Scalpel Front Triangle
The Scalpel's front triangle is hand-welded, heat-treated 6061-T6 aluminum, and features the Power
Pyramid down tube. The Power Pyramid simultaneously increases in diameter and decreases in wall
thickness throughout its length. As a result, the down tube has a weight-saving thinner wall and a
super-rigid, oversized profile at the bottom bracket shell to resist pedaling forces. At its upper end,
the Power Pyramid has a slimmer diameter for compatibility with the head tube and a beefier wall
for added strength.
The Scalpel also boasts easy portability, with an open, uncluttered front triangle that places all of the
suspension components aft of the seat tube. And for enhanced stand-over clearance, the Scalpel's
top tube has a downward bend just forward of the saddle - a feature that we fittingly call the Crotch
Notch.
