Who is Keith Bontrager? Working out of his California garage in the early 80s, Keith Bontrager developed a reputation for crafting some of the finest handmade bicycle frames and components around. Keith's mantra was simple: strong first, light second. Today Bontrager offers a full range of road and mountain bike components, all rigorously tested to meet Keith's stringent standards for fatigue and impact strength, and all firmly grounded in Keith's no-nonsense design philosophy, valuing performance and usability, not fads and gimmicks.
