THE SAM'S PANTS

Built To GO

Get lost, explore.  Ever wonder where that gravel road or singletrack leads to?  The 2025 Sam’s Pants is the bike that can take you there.  Handcrafted in the USA featuring modern geometry, double and triple-butted Columbus Zona tubing and UDH compatibility, this bike is built with the durability to bring you home.

REAL STEEL

Steel is the perfect, durable material for long days on mixed terrain, offering a smooth, compliant ride that naturally dampens vibration. The Sam’s Pants is built with Columbus Zona tubing specifically designed for off-road use.

UPDATED GEO

Available in 5 sizes (XS-XL) the Sam’s Pants is Built To Go.  We slackened the headtube, increased the reach and shortened to chainstays slightly to make this bike more capable than ever.  Wanna find out where that road or singletrack goes?  This is the bike.

WHY THE SAM’S PANTS?

We built our first gravel bike over 13 years ago. Unsure about drop bars—or skinny jeans—we named it after Sam, a local shop kid who rocked the latter. While we’re still on the fence about skin tight denim, one thing’s clear: nothing beats the sense of adventure found  behind the handlebars of a gravel bike.
