CLIMB EVERY MOUNTAIN, CRUSH EVERY SPRINT. THE LANGMA ADVANCED PRO DISC FEATURES A RE-ENGINEERED LIGHTWEIGHT AERO FRAME AND ALL-NEW GIANT SLR 36 DISC WHEEL SYSTEM WITH INTEGRATED DISC BRAKES AND HOOKLESS RIMS, PLUS CUSTOM LIV SADDLE AND HANDLEBARS, FOR POWERFUL, RACE-READY PERFORMANCE.
KEY PERFORMANCE FACTORS
The heart of the Langma Advanced Pro 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.
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.
The all-new tubeless Giant SLR 36 Disc WheelSystem reduces drag, while the adjustable Variant Composite Seatpost provides superior compliance, so you get a responsive ride that practically skims over rough roads.
TECHS & 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 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.
INTERNAL SEATPOST CLAMP
A lightweight, all-internal seatpost locking mechanism provides confident clamping force with clean performance and aesthetics.
The most advanced steerer tube technology in today’s Liv and Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2" lower, 1 1/4" upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.
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 drive side and stability on the non-drive side.
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.
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.
Tracking your power output and training data has never been easier. The all-new Power Pro system delivers accurate information with an integrated system that’s precise, reliable and simple to set up. The most effective training is smart training, so start training with power.
A massive rectangular downtube and oversized toptube 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.
HOOKLESS RIM DESIGN
Hookless rim design enhances overall durability and offers a wider inner rim width without adding extra weight. It also helps to create a rounder tire shape providing superior grip and handling as well as added sidewall support when cornering.
