SRAM Mullet Rival eTap GX Eagle AXS Gravel Upgrade Kit
With the SRAM Mullet Upgrade Kit you can give your gravel bike even more range! The Mullet Upgrade Kit combines two worlds in line with the area of application of gravel bikes: The Rival eTap AXS shifting brake system for dropbar bikes and the GX Eagle AXS MTB rear derailleur. With the large possible gear range of the Eagle cassettes, you can master the steepest off-road climbs and discover places that were previously inaccessible to dropbar bikes.
Rear derailleur
In contrast to the high-end XX1 AXS rear derailleur, the cage of the GX Eagle AXS rear derailleur is made of steel instead of carbon. This reduces the price and makes the rear derailleur even more robust on the trail. In return, you have to accept an additional weight of almost 100 grams compared to the top version. The tried-and-tested overload clutch provides better protection for the rear derailleur in the event of a fall. It briefly decouples the rear derailleur under extreme loads so that it can avoid the load and the electric motor is protected from damage. However, the rear derailleur immediately jumps back into the engaged gear. As a positive side effect, the rear derailleur suspension and the derailleur hanger are also better protected in the event of a fall. The Roller Bearing Clutch 3.0 vibration damper in combination with the X-Sync 2 tooth profiles of the derailleur pulleys guarantees reliable chain movement
Shift brake lever including hydraulic disc brake
With the Rival eTap AXS HRD shift-brake system, you can brake comfortably and in a controlled manner from any position and transmit your shift commands wirelessly. In contrast to the Red AXS and Force AXS shifters, the hoods of the Rival have become significantly flatter and narrower. Not only do they look great, they are also compatible with all hand sizes. The textured shift paddles and rubber grips are also new for even more control and comfort. The grip width adjustment on the brake lever ensures the best possible ergonomics, while the integration of the Rival into the AXS platform offers you the option of adapting the shifting to your personal preferences, evaluating your shifting behaviour or carrying out firmware updates via the associated smartphone app. In addition to the freely selectable assignment of the shift buttons, the derailleur can also be operated in semi-automatic mode, in which the rear derailleur and front derailleur synchronize automatically and you only have to choose between a lighter and heavier gear.However, there are no ports for additional shifters (blips), as found on the Red/Force AXS units, on the Rival AXS shifters. The two-piece brake caliper based on the award-winning HydroHC platform is beyond reproach in terms of braking performance and heat management.
Charger/battery
The integrated battery on the rear derailleur has a range of over 1000 kilometers. The charge status can be read at any time via an LED lamp and the battery is recharged within an hour using the charger supplied.
