Bontrager TLR Tire Sealant

Bontrager is a prominent American brand specializing in bicycle components, accessories, and apparel. The brand was originally founded by Keith Bontrager in 1980 in Sunnyvale, California, where it gained a legendary reputation for innovative, high-performance mountain bike frames and durable components. Keith Bontrager, an engineer and former motocross racer, applied physics and rigorous testing to create parts that could withstand the demands of off-road cycling, a philosophy that still defines the brand today.

In 1995, the brand was acquired by the Trek Bicycle Corporation, based in Waterloo, Wisconsin. Since the acquisition, Bontrager has functioned as Trek's primary in-house brand for aftermarket parts and original equipment. While Trek bicycles are manufactured globally in countries like Taiwan, China, and the Netherlands, specialty chemical products like the TLR Tire Sealant shown here are typically manufactured in the USA. Today, Bontrager remains a cornerstone of the cycling industry, providing everything from professional-grade wheels and saddles to essential maintenance products for tubeless tire systems.
