This is what we are known for. Paired spoking is when the spokes meet at the rim in pairs. In conventional wheels the spokes are evenly spaced. Tensioned spokes pull not only down toward the hub, but also outward toward the flanges. When spokes are paired at the rim, these left and right pulling forces are neutralized. If using conventional lacing, these lateral forces try to pull low spoke count wheels out of true. Pairing the spokes allows us to use fewer spokes on lighter rims than anyone. Found on all Rolf Prima wheel models.
Delta Rim Technology
Through computer aided modeling, design iterations and countless hours of wind tunnel, lab and field testing, Rolf Prima has developed a rim shape which greatly improves aerodynamics, ride feel and overall handling. The ultimate in any design is efficiency. For wheels, design efficiency manifests in saved weight and power savings which leads to increased rider speed. The Delta Rim Technology is a shaped profile that improves tire fit, creating a more aerodynamic interface with the tire as well as better tire support. Our wider tire bed fits tightly to the tire sidewalls smoothing airflow and better supporting the tire sidewalls. This improves turning precision, ride comfort and overall handling. A wide tire bed provides the base for Delta’s shaped sidewalls which are designed to continue smooth air flow along the rim and improve wheel stability in cross winds.
Dish Reducing design
Rolf Prima's Dish Reducing Design reduces the dish of the drive side spokes, increasing stiffness and making for a more stable and smoother ride. Dish Reducing Design technology is used on all Rolf Prima wheel models.
Differential Flange Diameter
Rolf Prima's Differential Flange Diameter technology transmits drive torque in the rear wheel across both flanges to increase the number of pulling spokes. This means even with Rolf Prima's low spoke counts, you still have the same number of pulling spokes as a traditional spoked wheel. Differential Flange Diameter technology is used on all Rolf Prima wheel models.
Jacketed Nipple Design™
Rolf Prima's Jacketed Nipple Design moves the spoke bend away from the high stress areas of the spoke, increasing spoke life. The Jacketed Nipple Design is used in all Rolf Prima deep section, areo rims.
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.
Aerodynamics - Wind Tunnel Results
Can Rolf Prima wheels make you faster? YES .. .. At 23 mph, 80% of an average rider's power output is used just to overcome the wind resistance. We have designed our wheels to decrease the wind resistance, meaning more of your power goes into relentless forward motion.
