Our Technology


AFTER MORE THAN A DECADE OF EXPERIENCE IN BUILDING THE WORLD'S FASTEST WHEELS BY HAND, ROLF PRIMA HAS EARNED ITS PLACE AS A LEADER IN HIGH PERFORMANCE WHEEL DESIGN.


PAIRED SPOKE TECHNOLOGY

Our Paired Spoke technology broke new ground when it was introduced in 1997. Bringing the spokes to the rim in pairs neutralizes the left and right outward pulling forces allowing us to build true wheels on lighter rims with fewer spokes. Fewer spokes and lighter rims help create increased aerodynamics and faster performing wheels.

DELTA RIM TECHNOLOGY™

Rolf Prima's Delta Rim Technology: In skydiving, the Delta track is the fastest position for gaining forward airspeed. Our Delta profile takes that cue using increased width and sidewall shaping to improve airflow and stability in straight on and crosswind situations. This wider rim is not just faster, but the additional tire support improves cornering and handling in all riding conditions.

 

INTERNAL NIPPLES

By using internal nipples Rolf Prima is able to reduce stresses on the nipple because the nipple is in compression. Building with internal nipples also decreases overall wind drag of the wheel, increasing aerodynamic benefits. Internal nipple technology is used on all Rolf Prima road and triathlon specific wheel models.

JACKETED NIPPLES™

The deeper the rim, the more a spoke must bend along its path to the hub flange. Our patented Jacketed Nipple Design moves the bend of the spoke away from the high stress area of the spoke threads and increases spoke life significantly.

SELF-ALIGNING NIPPLE™


Rolf Prima's Self Aligning Nipple Technology: This patented design allows the nipple to rotate in a ball and socket configuration to minimize bending in the spoke and increase spoke life.

DIFFERENTIAL FLANGE DIAMETER™


Our patented oversize non-drive Differential Flange provides the leverage to transmit drive torque in the rear wheel to the non-drive spokes, thereby increasing the number of torque absorbing spokes.

DISH REDUCING DESIGN™


Rolf Prima's Dish Reducing Design: This patented technology increases the bracing angle of the drive side spokes to improve wheel stiffness
