Supercaliber isn’t trying to be a traditional full-suspension XC bike. It’s a purpose-built race platform designed to climb like a rocket, accelerate instantly, and stay sharp when the course gets rough.\u003c\/p\u003e\n\u003cp data-start=\"781\" data-end=\"1109\"\u003eAt the heart of this frameset is \u003cstrong data-start=\"814\" data-end=\"842\"\u003eSLR OCLV Mountain Carbon\u003c\/strong\u003e, a high-modulus carbon layup engineered for maximum stiffness-to-weight.
