PHYSICS BEHIND BIG PULLEYS
The mass moment of inertia “I” is a measure of an object’s resistance to change in rotation direction. Its equation (I=mr2) where“m”is the mass (of the chain) and“r”is the radius (of the pulley) shows that with a bigger pulley (i.e. radius) you also get a bigger mass of the chain interacting with the pulley, resulting in a higher mass moment of inertia than with standard size pulleys.
The higher the mass moment of inertia is, the more momentum you can create and keep while pedaling at the same intensity. Therefore, Ridea OSPW evo helps you save energy to ride faster and longer.
FORGED CARBON COMPOSITE
Forged Carbon is the ultimate material for oversized pulley wheel systems and a far better alternative than alloys and plastics commonly used in the industry.
Forged Carbon is lighter than alloys to compensate the bigger size of the pulleys and cage system, while being harder and more durable than plastics.
Its elasticity and tensile strength allow a precise guiding and engagement of the chain. More importantly, we can design the bearings with minimum play to reduce friction, maximizing the energy savings of the overall system.
X-ODON
First developed by Ridea in 2010, the X-ODON technology of narrow-wide teeth is available for all pulleys with an even number of teeth (E60, F60, E48 and C26 series).
The teeth design, shaped with different lengths and angles, ensures a smooth engagement between the chain and the pulleys. Therefore, the X-ODON technology plays a fundamental role in making a rear derailleur cage with minimum play among its parts, reducing noise and increasing the overall performance of the system.
