Whether you're in it for the love of the climb, the rush of the descent, or the next PR, the Langma Advanced Disc is ready with its re-engineered lightweight aero frame and all-new Giant SLR 36 Disc WheelSystem (select models) with integrated disc brakes, plus custom Liv saddle and handlebars for powerful fit and performance.

Key Performance Factors:

- Accelerate faster
The heart of the Langma Advanced is a super-light Advanced-grade composite frameset, delivering a powerful stiffness-to-weight ratio for explosive acceleration. Updated truncated ellipse tubing reduces wind drag and boosts sprinting efficiency.

- Better handling
Integrated, flat-mount disc brakes deliver the confidence to carry speed into corners and navigate variable weather conditions. The Langma also accommodates tires up to 32mm, so you can customize your set-up for the road ahead.

- Vibration canceling
The tubeless Giant SLR 36 Disc WheelSystem (select models) reduces drag, while the adjustable Variant Composite Seatpost provides superior compliance, so you get a responsive ride that practically skims over rough roads.

Techs and 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 lightweight and stiffness with optimal compliance.

- Compact Road Design
When introduced by Giant in the 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward-sloping top tube (from the headtube to the seat tube) 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.

- Internal Seatpost Clamp
A lightweight, all-internal seatpost locking mechanism provides a confident clamping force with clean performance and aesthetics.

- 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.

- Powercore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-drive side.

- Variant Seatpost
This proprietary seatpost design optimizes the balance between lightweight and superior ride quality, with simple adjustments to enhance the total race performance of the Langma road range.

- Tubeless System
Engineered with proprietary Dynamic Balanced Lacing technology, this tubeless-ready composite WheelSystem delivers superior efficiency, pinpoint control, and comfort.

- MegaDrive
A massive rectangular downtube and oversized top tube work in unison to provide superior front-end lateral and torsional steering precision. The precisely engineered, rectangular-shaped downtube yields unprecedented steering and pedaling stiffness.
