Technological benefits
Polaris C25 R
We have specifically designed our Prymahl wheelset to be in perfect harmony with our clients’ expectations. We have applied the principle of Dynamic Response. 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.
EPS mouled rims
A counter mould, double moulding process is used, for the rim inner facing for a rim that is as perfect on the inside as it is on the outside leaving a clean surface with no residue, nor rim thickness variation for low rolling resistance nor lateral flex. If for us this invisible, to the cyclist, process is paramount on top end bike frame, it would seem to us, unavoidable on a rotating mass.
CNC-machined hubs
We have used flanges on our CNC-machined hubs for excellent value for money and performnce. 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 double butted 2/1.5 stainless steel spokes for the R series 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
