  • Open Cycle strives to make some of the highest quality bikes on the market! The Open ONE+ is nothing short of great! At less than 900g you've got a seriously light platfor for a hardtail build. This is a serious XC machine designed to fit wide tires so you can get as much traction as possible without too much extra. You can set this thing up as a mean lean efficient XC machine with some lightweight 29er wheels and tires or get down and dirty with 27.5+ tires up to 3.0" wide.

    The Open ONE+ is only offered as a frame only at this time. This is the perfect frame to start a custom build. We specialize in custom builds and we're happy to go all out or come up with a solution that is more butget friendly. Whatever you're looking to build we can build the bike of your dreams!

    On the cart page, please specify in the notes/special instructions section which size you would like.
