Muc-Off first debuted its L.O.P.S. (Lightweight Oversized Precision Shifting) rear derailleur pulleys awhile back, which were only available to their sponsored EF Education Easypost and INEOS Grenadiers WorldTour teams, as well as Elite IRONMAN triathletes Laura Philipp and Kat Matthews.
However, the British “anti-friction” experts are now offering a revamped version to the rest of us cycling mortals called the L.O.P.S 2.0, which is designed to work with Shimano’s Dura-Ace RD9100 and 9150 Di2 11-speed groupsets.
According to Muc-Off, the revamped L.O.P.S. 2.0 features the same “friction-coated”, aero-space grade aluminum 13-tooth upper and 19-tooth lower pulleys as the initial version.
However, a slight tweaking to the angle of the pulleys has resulted in even less friction – to the tune of 88% less when compared to standard alloy, and 71% less than anodized metal.
Additionally, Muc-Off claims the pulleys are 62% stiffer than the stock Shimano derailleur cages thanks to their mix of carbon fiber and 6/4 titanium construction.
Weighing in at a scant 79.4 grams, the L.O.P.S. 2.0 sells for £999.99.
