The new Prymahl Orion C50 Pro Disc Evo wheels are synonymous with performance, lightweight and versatility.
Featuring a 21mm internal width, the larger rim means there's more tyre aerodynamics, and a larger contact area with the ground for enhanced handling.
Reduced weight for more response and versatility on all ground types. Whether it's windy conditions, a mountain pass, or when sprinting, you won't be caught off guard. The C50s will get you where you want to go.
Fitted with low-friction hubs, they deliver optimum power transfer. Combined with the expertise of our wheel builders, these wheels are finely tuned to give you every watt you need.
These rims are 60 grams lighter than the previous version despite an internal width of 21 mm compared with the 19 mm on the previous version.

Build and customise your wheelset
Our configurator gives you the possibility to define yourself the equipment and the decals of your wheels, at no extra cost.
It's very simple: change the decals, the cassette body and the tyres as you wish. With each change, the photo, the technical sheet, the weight and the price are automatically updated.
Technological benefits
Orion C50 Pro Disc Evo
We have specifically designed our Prymahl wheelset to be in perfect harmony with cyclists' expectations. We have integrated our Dynamic Response concept. Stiffness is no longer the byword in frame and wheel design but responsiveness as the wheels must track the cyclist in their movement and efficiently transfer the power the cyclist is putting down through the pedals.
Our Prymahl C50 Pro Evo rims combine responsiveness, predictability, low rolling resistance and ease of use.
The results of months of research led us to develop a new fibre moulding technique called UML® (Unique Matrix Layup). The carbon sheets are assembled on the rim in one go around a single matrix. There are no junction points, no residues, no unnecessary layup, pure defect-free carbon fibre.
This new version of our internal mould enables us to obtain uniform fibre compaction under pressure over the entire rim.
CNC-machined hubs
We have used straight pull spokes on our CNC-machined hubs for optimal, concession-free performance. All our hubs are equipped with a cassette body with a minimum pick-up angle for optimal response.
As for the spokes, we have chosen stainless steel aero spokes for the pro range of rims. Stainless steel is more responsive, comfortable, and predictable than stiff alloy spokes.
We also decided to use exclusively extreme precision bearings fitted (to the hubs) in environmentally controlled labs so as to reduce torque and friction-free performance.
Manually fitted by our technicians in our factory.
We are extremely attached to the principle of know-how. For fitting, we have discovered that the only way to obtain perfect quality is to manually fit our hubs in our own factory.
All our rim technicians receive a thorough in-house training and especially in the use of tension meters. Spoke lacing requires a special skill for top performance wheelsets that respond to our clients' expectations
