It is characterised by top shifting performance with extremely low noise development. The secret is the built-in Xring rubber ring, which dampens the impact of the chain on the teeth of the idler pulley, eliminating the biggest source of annoying rear derailleur noise. With the absoluteBLACK Silent-Xring pulleys, your bike ist therefore significantly quieter than with conventional polymer or aluminium derailleur pulleys and approx. 60% (or at least 12 decibels) quieter than with the original SRAM shifting cogs. Full ceramic bearings are used, i.e. both the bearing balls and the raceways are made of ceramic. This way you benefit from maximum efficiency, long durability and mileage. Ball bearing cage and seals are made of low-friction polymer. The minimalist HOLLOWcage made of carbon and polymer and its colour-contrasting lower lockring create a spectacular look. It also contributes significantly to the fact that the entire system weighs only 70 grams.
