L.O.P.S 2.0 was designed, developed, tested, and hand-built in the UK for Shimano Dura-Ace RD 9100 and Shimano Dura-Ace RD9150 11-speed rear derailleurs. Why 11-speed only? Our in-house testing found 11-speed chains to be on average 36.6% faster than 12-speed; and L.O.P.S 2.0 is all about speed!
This state-of-the-art oversized pulley wheel system gives you a more efficient, consistent, precise gear change every single time, as it creates an optimised chain angle which reduces chain articulation and friction around the pulley wheels vs a stock set up – Less friction, more speed, greater efficiency.
The key factors that determine an oversized pulley wheel system’s efficiency are build quality, weight, stiffness and bearing efficiency, and some of these factors can work against each other, if one area is pushed too far. The art of developing the optimum system, is in the engineer’s ability to strike a perfect balance between these factors, to deliver maximum efficiency across the board. With the development of L.O.P.S 2.0 every aspect was analysed, every efficiency optimised, and every advantage maximized. Because when every second counts, every detail matters.
