Open One + Frameset
When the ground breaking OPEN frame, the OPEN O-1.0, hit the scene in 2012, the cross country mountain bike world got a taste of what advanced composites and an obsession with design could create. The O-1.0 remained the lightest production hardtail frame for several years, and is still lighter than nearly all hardtails offered by the competition today. Four years later, the dynamic German powerhouse has built on the success of the O-1.0 and created the next generation of ultra-lightweight, ultra-versatile mountain bike frame, the OPEN One+ Frameset. The OPEN One+ shares the O-1.0's uber-clean esthetic and is actually similar in weight, but that's where the similarities end. While OPEN likely could have shaved additional grams of frame weight, the advancements in the One+ focus on stiffness and versatility.
