Ratio Technology, known for their shifter upgrade kits and UK-made components, launched a derailleur cage for Eagle AXS derailleurs. Machined from 7075 aluminium, the new cage shares many features with its mechanical-shifting cousin but has updated geometry for compatibility with SRAM’s electronic MTB derailleurs.

The new cage features 14t and 12t jockeys running on stainless Enduro bearings and held together with full stainless hardware. The standout feature of the cage is its weight: At 79g out of the box, a Ratio cage saves 67g over GX AXS and 5g over X01 AXS. In fact, the cage aside, SRAM’s electronic derailleurs are all virtually identical in their construction. The result is that a GX AXS derailleur fitted with Ratio’s cage weighs the same – but costs less – than SRAM’s X01 model.

To add to this, the new cage fits on all SRAM’s Eagle AXS derailleurs – making it a replacement part that SRAM themselves currently don’t offer. Bending or breaking a cage should not write off a derailleur that could have cost you over £550/$750/830€, and now it won’t.

Ratio says, “It’s no secret that SRAM’s GX AXS derailleur is heavy – over 50% heavier than its mechanical counterpart. However, its shifting mechanism is identical to X01 and XX1. With our new cage, your GX AXS mech beats X01 spec for a fraction of the price. Plus, cutting weight at the cage reduces chain slap and unsprung weight and you’ll still have your steel GX cage for emergencies.”
