Open Cycles U.P. 2.0 Frameset - Unbeaten Path Carbon Gravel/Road
The Open Cycles U.P. 2.0 Frameset is the latest iteration of the bike that established the "gravel plus" category. It remains a masterclass in minimalist design, engineered by industry legends to be incredibly fast on the road yet virtually unstoppable off it. The core philosophy is GO for the Unbounded Path.
Unmatched Versatility and Tyre Clearance
The key to the U.P.'s versatility is its tyre clearance, achieved through the iconic dropped drive-side chainstay. The 2.0 frameset flawlessly handles two major wheel sizes:
700c Wheels: Optimised for fast riding with road and gravel tyres up to 40mm wide. 650 ext{b}$ Wheels: Allows the use of wide mountain bike tyres up to 2.1in (54mm), transforming the bike into a nimble, plush hardtail for tackling singletrack and extremely rough terrain.

Construction and Features: The U.P. 2.0 frameset is constructed from high-quality Carbon Monocoque, delivering an exceptionally low weight while ensuring the stiffness required for efficient power transfer. The frameset includes the matching Open U-Turn Fork, known for its low weight and precise steering.
For the modern builder, the frame maintains key features that prioritise performance and ease of maintenance:
Threaded Bottom Bracket: Uses a reliable BB386-standard bottom bracket shell, preferred by many mechanics for its ease of installation and reduced creaking.
Integrated Routing: Fully internal cable routing for a clean look, protecting cables from the elements.
Minimalist Design: No unnecessary mounting points or frills, keeping the frameset light and focused on speed and capability. The U.P. 2.0 is the definitive chassis for a dream build that truly eliminates the boundaries between road, gravel, and light mountain biking.
