Highlights
Lighter frame, faster climbs
The Advanced SL composite frameset drops 558 grams over its predecessor. Less weight to haul uphill means more speed for the same effort on race day.
Aero shaped to save watts
AeroSystem Shaping with truncated ellipse tubing delivers a measured 5.9-watt advantage. Free speed at every point in the course, no extra pedaling required.
Fit dialed to the millimeter
Four seatpost offset positions cover a 51mm range and the armrests offer 24 times more positioning options. Your TT or tri fit, exactly, not close enough.
Fuel without breaking rhythm
An integrated bento box and hydration straw keep food and water within reach. Stay aero and fed through the whole effort.
Integrated disc control
Disc brakes are built into the frameset for confident, consistent stopping at speed. Brake late and hard into technical corners.
