The Marvel 50D II was designed to be an all-round wheelset, that performs well on the flats, hills, and mountains. The wheelset weighs just 1500 grams for the pair, making it a serious upgrade over alloy wheels for the amateur rider. The U/V-shaped rim profile improves lateral airflow, increasing stability on fast descents and in windy conditions.
In addition to optimizing the rim design, the second generation of Marvel wheels comes with several upgrades, namely ETRTO-compliant reduced hooks to offer better aerodynamics, comfort, and traction, Alpina Ultralight Aero spokes, and lighter rims.
- Intended Use: Road
- SteelSpoke Wheelset

RIMS
When engineering a new wheelset, the first consideration is always the rims. For the Marvel II series, we started from the ground up. After listening to valuable feedback from our riders, we decided to create rims with wider tires in mind. Marvel II’s 31mm external rim widths are aerodynamically optimized for 28c and 40c tires. To take things further, we chose inner rim widths of 23mm, leading to an ideal tire shape that maximizes grip and comfort, while minimizing rolling resistance. We design, manufacture, and test our own resin, carbon pre-preg, and rims, allowing us to ensure our rims are of the highest quality and are free of voids and wrinkles.
What makes our clincher, tubeless-ready rims unique is that we use a reduced hook design. We see the benefits and drawbacks of standard hooked as well as hookless rims and have found a way to offer the best of both worlds. Our ETRTO-compliant reduced hooks allow for the aerodynamic, durability, and optimal tire shape that hookless rims provide with the security, tire compatibility, and ability to run higher pressures that a clincher can offer.
Additionally, our rims feature in our exclusive UNI technology. It offers wider and more modern inner widths, making them compatible with wider tires for enhanced performance and versatility.
SPOKES
In the Marvel II wheels, we are using Alpina Ultralight Aero steel spokes, which provide a significant weight savings over the last generation of Marvel wheels. They are some of the lightest racing spokes available, while offering added benefits such as excellent durability, longevity, and improved aerodynamics.
PERFORMANCE HUB
The Marvel 50D II uses our Motion hub, which features pawls-ratchet freehub mechanism, that has been tried and tested by our sponsored UCI pro cycling teams in World Tour races like the UAE Tour. It offers low rolling resistance and excellent longevity.
Just like all of our other designs, the Motion hub is made by us using 5-axis CNC machines. High-grade precision S&S ceramic bearings were chosen to improve their lifespan and reduce rolling resistance, saving you precious watts. While having high quality bearings is important, a perfect bearing seat fit is essential for optimal performance. Our CNC machines precisely machine bearing seats to 0.02mm tolerances, guaranteeing exceptionally low rolling resistance and improving longevity.
