Hopp Carbon Parts complete cage kit for Sram Eagle Transmission AXS 12s (XX SL, XX, XO, GX) and Sram XPLR AXS 13s (Red, Force, Rival) rear derailleurs. Side cages are made of carbon fiber and has got an aero design, the jockey wheels are Aero type Oversized 14-20T and made of carbon fiber, equipped with super smooth hybrid ceramic bearings, the hardware is 7075T6 Aluminum and grade 5 Titanium CNC made. Superior overall quality and great attention to detail, it guarantees better performance in terms of smoothness, stiffness, shifting precision, aerodynamic efficiency and weight saving as well as adding a touch of personality thanks to its attractive design. Just 69 grams weight , allow to save from 16 grams (XX SL) up to 60.5 grams (GX). UD carbon fiber finish with black anodized hardware. 100% Handmade in Germany!

Hopp Carbon parts manufactures entirely in Germany this special gear cage kit complete with pulleys for Sram Sram Eagle Transmission AXS 12s (XX SL, XX, XO, GX) and Sram XPLR AXS 13s (Red, Force, Rival) rear derailleurs. It replaces the original components guaranteeing better performances, adding a touch of personality and exclusivity to your bicycle.

The cage has got an aerodynamic closed profile with two monocoque carbon fiber molded rocker arms. The result is a component with almost monolithic characteristics that guarantees great stiffness and resistance with a low weight. It should therefore not be compared with products made from a banal flat sheet, the specific design and the most valuable production technology allow shapes to be optimized to obtain a superior result in aerodynamic, structural and aesthetic terms.

The cage features a predominantly unidirectional (UD) carbon weave finish, the hardware, i.e. the fixing plate to the gearbox and the threaded bushes onto which the pulleys are screwed, is also made of 7075T6 CNC aluminum with a black anodized finish.

The pulleys are of the Oversize type and have 14 teeth (upper pulley) and 20 teeth (lower pulley), they are made of high quality carbon fiber with unidirectional (UD) weave finish. The closed aero design allows greater stiffness, better aerodynamic performances and prevents the accumulation of dirt. The shape of the pulleys and the profile of the teeth is differentiated between the upper and lower pulley, the teeth of the upper pulley are more accentuated to guarantee greater shifting precision, while those of the lower pulley are less pronounced to optimize smoothness.Â

The pulley bearings are of the hybrid ceramic type with very high smoothness but also very resistant to wear and corrosion thanks to the ceramic spheres and the stainless steel cage. These are high quality bearings that are assembled to very tight tolerances and individually calibrated to ensure the best possible performance. They are obviously equipped with external dust covers made to measure for the pulleys. The bolts that fix the pulleys are special made of grade 5 titanium with a lowered head and a black galvanic finish. Â

The cage kit weight only 69 grams (70.6 grams with fixing bolts) which is a great result with oversized pulleys. Allows a weight saving from 16 grams (XX SL) up to 60.5 grams (GX).

Weight saving, however, is not the main advantage, in fact the benefits in terms of smoothness are much more evident thanks to the larger diameter pulleys (the chain follows a path with less sharp curves which reduce friction and wear of the chain itself) and the very low friction ceramic bearings. The Aero profile of the faired cage ensures better aerodynamic efficiency while the oversized carbon fiber structure guarantees greater stiffness and, combined with the carbon pulleys, also more precise shifting. We leave the aesthetic aspect for last which is certainly subjective but the racing and refined design is very impressive and turns out to be one of the most iconic elements in every Dream Bike worthy of the name.

Installing is a rather simple operation that does not require any particular equipment or skills but only common sense and attention. The only recommendation is to use a new chain when assembling the cage kit, this for two simple reasons: the first is that since the diameter of the pulleys is increased the chain loop is longer and consequently a chain with a few more links is needed compared to the original configuration, the second reason is that a used chain, and consequently already lengthened, would create problems on the profile of the teeth of the new pulleys, wearing them prematurely and creating harmful friction which could not only undermine the advantages of smoothness but also worsen shifting performance.
