Ospw AERO System Coated for Shimano

The CeramicSpeed OSPW AERO System Coated is an oversized pulley wheel system designed to reduce drivetrain friction and improve power transfer on Shimano-equipped road bikes. For Indian riders chasing efficiency on long Ghat climbs or flat expressway segments, reducing drivetrain loss is a measurable, real-world gain that adds up over every kilometre. Cobbled Climbs is the authorised retailer for Ceramic Speed in India.

Use Cases

Daily training. Reliable construction for repeat use.

Race day. Lightweight, stiff design for power transfer and aerodynamics.

Fit adjustment. Right stem length critical for comfortable bike fit.

Our Take

At Rs. 65,000, the CeramicSpeed OSPW AERO System is a serious investment aimed at performance-focused riders who have already optimised their bike and want to extract more from every pedal stroke. The coated ceramic bearings handle India's dusty, humid conditions — including post-monsoon grime on Pune–Lonavala climbs or Chennai coastal rides — better than standard steel bearings. This is drivetrain efficiency taken to its logical conclusion.

Sizing for Indian Riders

This system is designed specifically for Shimano drivetrains — confirm your exact groupset generation (Ultegra Di2, Dura-Ace, or 105) before ordering, as pulley cage geometry varies between generations. No European sizing conversion applies here, but Indian riders in high-heat conditions (35°C+ in Delhi, Hyderabad, or Ahmedabad) benefit from the coated bearings' reduced heat-related friction degradation compared to uncoated alternatives.

Compatibility Notes

Compatible with Shimano road groupsets — verify your specific groupset generation for correct fitment. The OSPW cage replaces your existing rear derailleur's pulley cage. Coated ceramic bearings require less frequent servicing than standard bearings but should be cleaned after monsoon riding or prolonged exposure to road grime. Follow CeramicSpeed's recommended service intervals for bearing longevity.

Pairs Well With

To complete a low-friction drivetrain build, consider pairing with a quality wax-based or ceramic chain lubricant, a Shimano-compatible performance chain, a precision torque wrench for correct installation, and a chain wear indicator tool to protect your new pulley wheels from a worn drivetrain.
