FSE 40DH MTB Tubeless Carbon Wheels



FSE Carbon Technology in a Mountain Bike Wheel "was" our top request when we released our first ultra strong, stiff yet super light rims.  It makes perfect sense of course. They spin up super fast yet are the strongest carbon fiber rims available.

29er Weight: 1705 Grams
27.5 Weight: 1645 Grams
using DT Swiss 240 hubs

Our designers and engineers hit it out of the park.  All the stiff, strong light characteristics FSE is known for in a bad ass MTB.  This 40mm wide, 30.4mm internal and 30mm deep rim is the perfect down hill wheelset.

Our computer controlled carbon technology allows us to create the spoke and valve holes during the manufacturing process.  Yet another feature that adds to the strongest carbon fiber MTB rims.

Special Details

Filament Spin Evolution

Next Gen Carbon Fiber - Computer Controlled Carbon fibers are bathed in resin before spinning around a proprietary mandrel resulting in 100% efficiency and maximum quality.

Lightest Carbon

Less is Lighter! 100% accuracy in our carbon fiber process means less resin and material waste.

Stronger & Stiffer

MORE CONTROL. FSE Wheels are uncanny in their cornering performance due to their lateral stiffness thanks to the Filament Spin Evolution carbon process. NO HIGH SPEED WOBBLE. SHARP CORNERING now feels effortless.

º240C+ Hi Temp Brakes

SAFER. High Temperature resin and stringer carbon allows for excellent heat handling and dissipation.


Filament Spin Evolution method carbon fiber is a far more energy efficent way to build carbon fiber. Only one oven process is used. The FSE method also produces much less waste as it is computer controlled to 100% quality.
