TECHNICAL DATA

The overall energy saving of the OSPW system for Shimano Dura Ace 9200 and Ultegra 8100 reaches 30%-60%, or more in some cases, than a series configuration. Oversized pulleys last 3-5 times longer than standard pulleys commonly used on the market.

Note that although there are visual similarities in the OSPW 9100 series and in the 9200 OSPW series, spring voltage settings, rotation stop tower positioning and mounting pin depth are slightly repositioned and therefore systems are not compatible with each other. The 9200 derailleurs will require the new derailleur body washer included.
