Bespoke Geometry
Crucial point for an adapted bike, the geometry of your frame is defined according to your riding style, your dimensions, and the ideal behaviour you are looking for.
Custom Finish
With Vulcain, your bike will be unique. We offer a wide choice from our catalogues, or from our partners, with a total of almost 6500 shades available.
Choose your Build
We offer the Magma DH as a frameset only, as a complete bike with 2 setups available, and as a custom build on quotation, with a total choice of components.
Built to last
Our high-grade Steels allow the Magma DH to be extremely durable and resistant to all types of impacts, thanks to their mechanical strength and ductility.
A bike designed to go fast and far!
With its high strength steel tubes, 200mm of travel, and a progressive and sensitive 4-bar linkage kinematics, here is the MAgma DH, our downhill frame, solid, fun and efficient.
Get on the chairlift or go up in the shuttle, to the top of the slopes. Always ready for a good dose of adrenaline, the Magma DH will go down without worrying about rocks and roots, and will handle the biggest jumps and turns.
Efficient and nervous when you need it, tolerant when you’re on the edge of a riding mistake. All this with incredible durability, staying dynamic even after many years of riding.
Designed with the best materials and technologies:
- Front triangle made of Reynolds 921 stainless steel. Rear parts in Reynolds 853 steel.
- Machined parts in 15CDV6 steel, a reference in motor sport and aeronautics.
- 3D metallic printing on the swingarm, in Maraging steel, ultra resistant.
- Linkage parts and bolts in anodised 7075-T6 aluminium, aircraft quality.
- Rear shock axles in high performance stainless steel.
- Enduro Bearing MAX double row range, for increased durability and reliability.
- Anti-corrosion treatment, for total protection, even after a paint chip.

A sensitive, progressive and responsive suspension, ready to deal with any situation
The Magma DH has been designed to be super efficient with a ” 4-bar linkage ” kinematics, creating a deformable parallelogram, with a virtual pivot point . This system makes it possible to combine and optimize many suspension parameters thanks to the great freedom of trajectory of the rear wheel.
Leverage ratio
The suspension kinematics on the Magma DH is progressive, by about 38%. The ratio decreases throughout the travel, which translates into a very high sensitivity on small bumps, a good support in the middle of the travel and a very good firmness at the end of the travel to avoid bottoming, which allows to keep control on big landings and to improve the stability of the bike.
Anti-squat and Anti-rise
Anti-squat is the action of pedalling on the suspension. At the SAG level, this is about 120%, allowing for efficient and responsive acceleration, without pump effect.
Anti-rise is the action of braking on the suspension. Between 55% and 65%, these values are ideal and ensure a good stability of the geometry with a suspension that remains active under braking or in very rough sections.
Rear axle path
Moving backwards at the beginning of the travel, the trajectory of the rear wheel allows the suspension to gain in sensitivity, and the bike in speed which gives a good nervousness in the technical zones and at the exit of turn. In the second half of the travel, the path reverses, forcing the bike to slow down and stabilise on big landings like jumps.
