AXS HRD shift-brake system
Braking with just one finger? The SRAM Force Shifter makes it possible. Thanks to stiffer brake calipers and the newly designed shift/brake levers with optimized pivot point, you can generate more braking power in all handlebar positions with significantly less hand force. Thanks to their ergonomic design and grip width adjustment, the shifters are comfortable to use for a wide range of hand sizes. Another highlight are the additional shift buttons integrated into the hoods, which can also be used to operate ANT+-enabled bike computers. The textured main shift paddles work according to the proven eTap shift logic. One rocker switch for upshifting and one rocker switch for downshifting. If both paddles are operated simultaneously, the front derailleur is shifted. The shifting behaviour can be personalized via the SRAM AXS app and additional SRAM Wireless Blip Shifters can also be integrated. Bleeding Edge technology ensures simple and clean bleeding. Thanks to the slim design and the carbon brake levers, the Force AXS HRD system is significantly lighter than the previous version.
Paceline brake rotors | Center Lock
The Paceline brake rotors take up the elegant design of the AXS Road groupsets. With their optimized ventilation holes, they ensure smooth and low-vibration braking performance. The rounded edges on the top of the rotor minimize the risk of injury and comply with the guidelines of the UCI cycling world federation. Another advantage is that they make it easier to install the wheels, as the rounded top prevents jamming in the brake calliper.
Front derailleur
The revised Force AXS front derailleur ensures even more precise and faster shifting. Thanks to a narrower cage with an optimized shape, shifting operations on the large chainring and shifting operations under load are even more reliable than with the previous version. The front derailleur was designed for the 2x SRAM X-Range chainring gradations with 13 teeth between the large and small chainrings.Equipped with the proven Yaw technology and autotrim function, the front derailleur runs smoothly in every gear combination. The force when shifting with an AXS shifter is automatically regulated over the entire shifting range. The adjustment tool included in the scope of delivery ensures perfect adjustment of the front derailleur. The electronic wireless eTap shifting logic ensures intuitive shifting processes and simple, wireless setup. With the integration of AXS technology, the shifting behaviour of the front derailleur can be personalized via the associated app. The necessary power is supplied by the proven SRAM eTap battery.
Rear derailleur
Lighter, faster and with more capacity. The newly designed Force rear derailleur with its carbon rear derailleur cage saves 12 grams compared to the previous version. It can be used with cassettes from 10-28 to 10-36 teeth so that you are equipped for any terrain. The enlarged derailleur pulleys ensure even more efficient chain running. Thanks to the X-Sync tooth profile and chain management technology, the chain is guided safely even in poor road conditions. You can configure and fine-tune the rear derailleur using your smartphone via the SRAM AXS app. An ANT+ transmitter integrated into the rear derailleur enables communication between your bike computer and the rear derailleur.This allows you to display information on the battery charge status and the current gear ratio in your cockpit.
Chain | 114 links
With its milled inner and outer plates, SRAM was able to save a few grams of weight on the Force-Flattop chain. Thanks to the hard chrome coating on the inner plates and rollers, the chain can withstand tough shifting maneuvers and has an increased service life. The chain is easily locked with the enclosed Powerlock chain lock.
Charger/batteries
The integrated batteries on the rear derailleur and front derailleur have a range of over 1000 kilometers. The charge status can be read at any time via LED lights. The batteries for the rear derailleur and front derailleur are identical and can therefore be replaced on the move. The batteries are recharged within an hour using the charger supplied.
