Rolf Prima technology - Delta Technology
 

After more than a decade of experience and building the world's fastest wheels by hand, Rolf Prima has earned its place as a leader in high performance wheel design. Being different has defined us, but the proof is in our technology and extraordinary performance.


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.

Better Built:
Most bicycle wheels sold today are built using machines. For run-of-the-mill wheels this can work, but to build a truly light wheel with uniform tensions, you just can't match the skill of human hands. Every Rolf Prima wheel is carefully hand-built using a painstaking build process that enables our wheels to run true longer - without the need for constant attention or a "break-in period."

The Result:
With all of these technologies combined, Rolf Prima builds wheels with qualities once considered mutually exclusive: paired spokes, fewer spokes, lighter rims, higher spoke tensions, and great stiffness.
