THIS FEATHER-LIGHT RACING BIKE DELIVERS THE SPEED AND STRENGTH NEEDED FOR ANY CLIMB, RACE OR RIDE.
Key Performance Factors
Lightweight
The compact Advanced-Grade Composite frame, slender tubing and stiffness tuned for the female rider make for a serious climbing weapon.
Aero-features
Innovative tubing designed to slice through the wind without sacrificing weight or stiffness.
Precise Handling
This climbing weapon can tackle the descents or any technical flat corner, with appropriate lateral stiffness and control.
Why We Love It
Handcrafted for the toughest climbers, aspiring racers, seasoned competitors and passionate cyclists alike, Langma Advanced Disc is built with cutting-edge, lightweight aerodynamics to fly up steep grades and long climbs. The frame’s slender tubing creates an extremely fast and lightweight racing machine, while the downtube thickens as it approaches the PowerCore bottom bracket for pedaling stiffness strength.

Technologies & Features
Advanced Composite Technology
Liv’s High-Performance Grade raw carbon material is used to produce this frameset in our own composite factory. Using state-of-the-art materials and manufacturing techniques, Liv’s Advanced-Grade Composite frames are designed to offer light weight and stiffness with optimal compliance.
Compact Road Design
When introduced by Giant in 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeterwide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
OverDrive
Designed to provide precise front-end steering performance, this fork steerer tube technology uses oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
Variant Seatpost
This proprietary seatpost design optimizes the balance between a lightweight and superior ride quality, with simple adjustment to enhance the total race performance of the Langma road range.
3F: Fit, Form, Function
Fit, Form, and Function — Liv’s data-driven approach to building bikes for women.
Fit: Liv analyzes data on human body dimension, muscular strength and muscular activity, then considers the type of riding the rider will be doing, to build a frame that is fine-tuned through athlete feedback cycles with the goal to fit as many women as possible.
Form: The bike’s outlook takes the form with the intention to create a strong bond between the rider and the bike. The designers match the performance level of the bike with a beautiful and inspiring outlook.
Function: The componentry of the bike is carefully selected and the composite layup is uniquely crafted to give the rider an unprecedented performance edge and comfort
Tubeless System
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
