Overview
Longhorn was initially announced in year 2014 for world touring riders. It is specially designed for road drop bar with heavy loaded bike touring. With time tested, it has been approved to be a reliable partner to help you explore the world.
In 2019, Longhorn made some upgrades based on his predecessor. Totally new designed dropout provide more stronger M6 rear rack boss and integrated with Rohloff OEM2 boss. Handle bar stabilizer will prevent road drop bar hit the frame when parking when front rack is heavy loaded. Kick stand plate is convenient for commuter usage. On the other hand, features like 3 bottle cages, rack & fenders ready are all remained.
We use 4130 Cr-Mo tubes to build this frame as one of the most reliable, comfortable, recoverable material we've ever discovered. 1.2-0.9-1.2mm double buttered main triangle is stronger than most steel frames. Coordinated with 460mm length chain stay, it is suitable for heavy loaded touring without sacrificing much performance.
