ORA4571 Carbon Rims - The Reference For Wide Tires.
The ORA4571 rim profile is the result of Effes Industries' weighted curve regression. This algorithmic approach solves variables that result in performance metrics. Effective. Efficient. Do it right and do it best. The ORA4571 profile bests the aerodynamic challenge to ride wide tires even faster. The ORA4571 profile is 45 millimeters in width and 71 millimeters in depth. Effes Industries ORA4571 carbon rims are unique ‒ very fast, easy to handle, light, stiff, comfortable and durable. ORA4571 rims include advanced structural features that offer functional benefits for off road cycling.
ORA4571 carbon rims functionality stems from the sophisticated material distribution. The triple U-beam profile of the Triga rim shoulders make a rock solid rim well and harmonized rim sidewalls. Wide Triga rim shoulders shake off impacts and reduces the risk of pinch flats. The rim's bead hooks claw the tire for a secure seating. ORA4571 rims harmonized sidewalls act as a leaf spring that dampen road vibrations.
Effes Industries Magnesium Alloy Hubs.
Effes Industries' machined magnesium‒alloy hubs show excepional strength‒to‒weight ratio. DLC surface treated for superb wear resistance, ABEC‒9 stainless bearings and titanium axles/driver hardware ensure low drag and long lasting service life. The all exquisite hubs are available in 100/142 mm and 110/148 mm Boost standards; both with 16 and 24 spoke count.
ORA Wheels Are Titanium Laced.
Effes Industries ORA Wheels grant exceptional stiffness, longevity and ride quality. ORA4571 rims and Effes Industries' high tech magnesium hubs are laced with UHFS titanium bladed spokes and nipples. The special annealing give the titanium spokes ultra high fatigue strength. These spokes offer the highest vibration damping for any solid spoke and superior durability. ORA Wheels remain smooth under load, yet elevated spoke tension ensure ORA Wheels' instant power transfer and to spin true under advanced conditions: Made for tough gravel racing.
