OSPW + OverSized Pulley Wheel System +
OVERSIZED PULLEY WHEELS OSPW OLD TECHNOLOGY, TIMELESS EFFICIENCY. SIZE MATTERS? Pulley system s earliest application was Archimedes who developed the first documented block and tackle pulley system, as recorded by Plutarch. Plutarch reported that Archimedes moved an entire warship, laden with men, using compound pulleys and his own strength. Bicycle drive chain is a compound pulley system that proven to be most energy efficient way to ride by men power. Main reason to upgrade from 11 tooth derailleur pulleys to Oversized Pulley System is to reduce drive train friction, increasing chain length and ultimately, save watt. Oversized Pulley has larger radius, that creates longer circumference and more contact surface with chain links. Less angle bends in a chain ring cause less friction. To cut friction in whole chain drive system needs more than using larger pulley wheels. Good quality bearings in both pulley wheels, rear hub, bottom brackets are essential application. RIDEA has them all. 01
RIDEA s OSPW + BIGGER PULLEYS, AND MORE! More than simply larger pulleys, OSPW + applied innovative engineering and additional details to ensure minimal friction and problem.

PHYSICS BEHIND PULLEY + MASS MOMENT OF INERTIA Any measure of energy saving is critical to achieve better record. RIDEA OSPW + is the missing link to race bike chain drive evolution. I = MR² CHAIN OUT R Radius from Axius Equation of Mass Moment of Inertia I = Ratio of Mass Moment of Inertia M = Mass (Chain Mass) R = Radius from Axius (Center of Pulley to Center of Chain) Bigger pulley means greater R. More teeth T on the pulley drives more M, results in much greater I. When you have more I when pedal, it helps gain momentum to your drive in equal efford. For conditions like long distance or fast speed riding, BIG PULLEY helps you reduce fatigue and prolong riding time. m2 m1 m3 UPPER PULLEY LOWER PULLEY m4 M = m1+m2+m3+m4 Total Chain Weight on Pulley CHAIN IN 03

CARBON PULLEY + As one of the key components in chain drive system, PULLEY+ material need to be durable to bear wearing, and be elastic enough to allow bending stress during shifting. Alloy OSPW pulleys in market are durable, but not so elastic to handle bending stress. Their solution is to allow larger play between bearing and pulley to guide chain link for secure shifting. Result of this creates more friction, and lowered performance of OSWP. Ridea s PULLEY+ are made of Thermo-Formed Carbon Fiber. It is hard as steel, excellent elasticity and light weight. With X-Sync design to help chain link shifting between gears smoothly, PULLEY+ has minimum play between pulley and bearing, therefore less friction, save more watt, better racing performance. 05
SYNC DESIGN FOR ALL PULLEY + RIDEA developed X-Sync design in 2010 for MTB single chain wheels, later applied to next generations of most RIDEA s chain drive wheels and products. Better than uniform teeth design in market, X-Sync design altered the length, sliding angle of each tooth and widered every second tooth, to allow PULLEY+ easily guide the chain within 15 degrees of chain bending. Upper pulley in the market are made with play for easy sfifting. Application of X-Sync design allows PULLEY+ has minimun play yet easy shifting. Other benefit of carbon PULLEY+ with X-Sync design is noise reduction while pedaling. OSPW + X-SYNC PULLEY CHOICE SYNC Pulleys are available for 6 = 16T 8 = 18T 06
