HAND-MADE HOTNESS

Siren Bicycles is a hand-built American mountain bike company, in Idyllwild, California. We strive to build elegant, beautiful racing frames & complete bikes. Siren merges custom frame-building techniques with cutting-edge technology to bring you the finest racing machines possible.

Each Siren is hand built, with an eye toward the racer's needs. Each frame size gets its own tube set, tuned for ride quality & optimal weight.

Siren uses 7005 aluminum & Scandium tubing from Easton, Columbus, and Fairing; as well as the best butted steels from True Temper and Reynolds, mated to custom machined parts to bring you five stock sizes in all models. Additionally, Siren offers custom options & full custom builds.

JOHN HENRY

With much anticipation... the Steel Drivin’ Man. Siren's first “standard handbuilt” frame is ready to go… anywhere you want to. In honor of the John Henry namesake, Siren builds this 29" hammer-swinger the old school way- in the USA, by people who ride & love building bikes, and take pride in their craft. John Henry takes on the machine, bringing quality and performance comparable to high end custom frames at a production bike price.

TRAUCO

The Trauco will carry you deep into the backcountry and get you home in time for dinner. This racy 29"er was designed with all-day comfort & stability in mind.

This purebred 29er is ready to eat up weekend - or weeklong - singletrack. The Trauco will accommodate up to 2.5"” tires and is complemented well with optional Ahrens sliding dropouts as a singlespeed. It's built with ultra-light Easton size-specific stays & main tubes for a comfy, not-too-flexy ride. And like all Sirens, this race steed is born already acclimated to thin mountain air in Idyllwild, California.
