Highlights
Featherweight efficiency: The heart of the Langma is an ultra-light Advanced SL-Grade Composite frameset-which we’ve rebuilt with longer, more continuous pieces of carbon fibre for a stiffer bike that’s 60 grams lighter.* So you get a responsive ride that accelerates immediately, skims over rough roads and surges up climbs. And a translucent frame coating shows off this carbon construction, making the Langma look as fast as it feels.
*Compared to the first-generation Langma Advanced SL frameset
Intuitive handling: We’ve re-engineered the Langma fork for 50% more lateral stiffness* for precise handling and responsiveness. An oversized headset and all-new Liv Contact SLR handlebar boost control without sacrificing aerodynamics. Integrated, flat-mount disc brakes deliver stopping confidence in varied conditions. The Langma even accommodates tyres up to 32mm for extra grip in the corners and cobbles.

Aero advantage: Updated truncated ellipse tubing reduces wind drag at a wider range of yaw angles, gaining you precious seconds in flats, descents, and headwinds. Our relentless testing and refinement have also inspired the development of the new fully-carbon Variant SLR seatpost. Plus, the CADEX 36* Disc WheelSystem with side-drag control lets you stash more watts for the sprint finish.
*Available on SL Disc 0 model only

| Weight | The most accurate way to determine any bike's weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality. |
