A derailleur cage for enduro and e-bikes? That is lighter and at the same time more stable than the original? After extensive development work and numerous prototypes, we have succeeded in designing a technically and visually outstanding cage. The one-piece construction increases the rigidity, which enables significantly more precise gear shifting. This is noticeably improved, especially under high loads and in heavy gears. We have also drilled a second hole for the clutch spring in the SRAM Eagle cage, which allows more spring preload, which significantly reduces chain slap. Enduro Bearings ZERO Ceramic Hybrid bearings are installed, which were specially developed for MTB use. We chose this bearing because it is the ideal combination of a long service life and smooth running.
