Thesis’ OB1 build specs are great but what if you already have parts and just want to buy a frame? Well, this week they announced the new OB1 frameset modules. Whether you’re looking to run some vintage parts, a flat bar, Campy, or Microshift, Thesis’ frame module allows you to build their frame the way YOU want to.

The OB1 frameset modules cost $1499 and complete OB1s start at just $2999.

-Frame and fork (including bolts and spare frame hardware)

-Thesis Hollow-Forged Alloy Cranks with Choice of Chainring
