Langma Advanced Pro 0 (Pro Compact)

The Liv Langma Advanced Pro 0 - Pro Compact is a pinnacle-level women’s road racer for 2026, designed to deliver "QOM-level" efficiency. This 3rd-generation Langma (the sister to the Giant TCR) has been completely re-engineered to be lighter, stiffer, and more aerodynamic. While it retains its reputation as a legendary climbing bike, the 2026 model introduces truncated ellipse tubing and the OverDrive Aero system to significantly reduce drag on flats and descents.

This "Pro Compact" build is the flagship of the Advanced Pro range, featuring a full Shimano Ultegra Di2 electronic groupset and ultralight Giant SLR 0 40 Carbon wheels with carbon spokes, making it a race-ready machine straight out of the box.
