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.

FEATURES
- US-made Paragon sliding dropouts- the undisputed best in the business. You can lay tracks with derailleurs, or hammer on one gear. John Henry comes with a derailleur hanger.
- Disc brake torque brace enhances braking power and boosts frame integrity in a high stress area.
- S-bend stays and a 73mm bb shell accommodate the fattest tires you can find, even in the “short” setting on the sliders.
- Tucked away brake line routing protects your fancy brakes in case of a crash.
- Frame weights are competitive with other high end steel frames, coming in a full 1/4 lb lower than the leading steel production 29er
- John Henry is true to Siren roots with a bent, premium quality top tube. Despite the added expense, we still believe in maintaining good standover clearance & enhanced ride quality.

SONG 29
Great Divide Proven. Designed as our backcountry long hauler, the Song29 has already done well in The 2,711 mile Tour Divide, Leadville 100, Vapor Trail 125 and many big excursions. The Song has 1 1/2" of active, comfortable suspension travel, yet it remains efficient enough to hammer on for hours, even days, on end. Like all Sirens, it's purpose-built & ready for customization.

Song 29 Geometry
FEATURES
Lightweight, yet stiff & responsive
The Song combines the optimized weight & stiffness of aluminum with isolated flex in the titanium. With size-specific tubing we tune the frame stiffness while keeping the weight down. We designed the flex-plate with the help of computer modeling & Finite Element Analysis, assuring optimal lateral & torsional stiffness. Frame weight is 4.25 lbs for medium.
Active, tunable travel
Built around a Cane Creek damper, the Song can be tuned for sensitivity to the smallest bumps, even for lightweight riders. Likewise, the air shock can be firmed up to activate only under bigger hits.
Low maintenance & easygoing
The Song has no bearings to maintain; just silent, pivot-less flex. The Song is designed to be durable with ultra-endurance racing in mind. In a pinch, the frame can also be disassembled and packed small for travel and it can fit in your grandmother's old suitcase.

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.
