Speedhound Design Bureau

Speedhound's ONLY ONE™ bicycle frameset is designed to maximize your drivetrain and build options.

Designed and built in Minneapolis, the ONLY ONE bike frame features our patent-pending Speedhound Dropout System™ (SDS). This allows the ONLY ONE to be configured (and reconfigured) to suit virtually any riding style and drivetrain preference. It even allows you to use a belt drive on your Speedhound bike instead of a chain.

Based on a cyclo-cross bike geometry, the Speedhound ONLY ONE also features a wide fork crown and HouseBend™ chainstays that can accommodate 700 X 35 tires, large chainrings, and narrow chainlines. There are few limits to what kind of bike this frameset can be.

Want a road or touring bicycle? Build it up with your favorite road group. Is light trail riding your thing? Do it cyclo-cross style. Prefer the simplicity of a single speed or fixed gear bike? Bring it! Want a low maintenance city bike? Set it up with a belt drive and geared hub. This frameset is the ONLY ONE you’ll ever need.

And as if that weren't enough, it's available in 8 colors – all of which are embellished with silver-plated brass headtube badges AND fork crown medallions.
