The microbore hose features clear coating, PTFE inner liner, stainless steel braided armor, and polished stainless steel hardware The micro sized hose OD allows an unmatched bend radius, making it perfect for routing through forks, frames and bars The PVC hose coating adds great looks, abrasion protection to expensive parts, and resistance to damaging UV rays The PTFE liner is an inert material, compatible with all hydraulic and brake fluids, has a heat range of -158° to 500°, and shields brake systems from moisture, unlike other materials like nylon The stainless steel armor braid is superior in pressure rating, flame resistance, and volumetric expansion to all other materials, including Kevlar, resulting in unmatched stopping power
