World’s first one-piece cage

A rear derailleur cage for enduro and e-bikes? Which 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 rigidity, which enables significantly more precise shifting. This is noticeably improved, especially under high loads and in heavy gears.

We also drilled a second hole for the clutch spring in the SRAM cage, which allows for 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 long service life and smooth running.

Specifications:

  • Application: MTB from XC to Enduro, to E-MTB.
  • Material cage: 7075 aluminum
  • Material pulleys: 7075 aluminum
  • Bearings: Enduro Bearings ZERO Ceramic Hybrid
  • Variants: SRAM AXS, mechanical; Shimano SLX- XTR
  • Derailleur Pulleys: 12 tooth (upper derailleur pulley), 14 tooth (lower derailleur pulley)
  • Color: black, natural, bronze
  • Weight: 85g (SRAM)/ 79g (Shimano)
  • Why not oversized pulleys?

    We deliberately decided against larger pulleys because they change the pulley-to-cassette ratio. As a result, shifting processes deteriorate and the probability of defects increases.

  • What is the advantage of the one-piece design?

    The one-piece construction massively increases the torsional stiffness, which allows us to keep the weight low with increased stability.

  • Why do the teeth have a narrow wide shape?

    By using alternating thick and thin teeth, the chain remains much more stable on the rollers.
