The Eagle 90 Transmission combines the stability of the full-mount attachment with simple installation and a shifting quality that remains constant even under high loads. It also has an easily repairable rear derailleur. The Eagle 70 Transmission offers high robustness and reliable function and is compatible with all T-Type components.

Thanks to the hangerless interface, the rear derailleur is fixed directly to the frame, eliminating the need for a separate derailleur hanger, as is already known from Sram's Eagle Transmission AXS. This prevents incorrect settings and ensures consistent performance regardless of the frame design. In addition, the rear derailleur can rotate backwards in the event of an impact to minimize damage.

The assembly of the mechanical derailleur groupset is also deliberately kept simple. After attaching and tightening, only one shift cable needs to be routed and pre-tensioned. The mechanics of the shifters have been redesigned to ensure ergonomic operation. The shift cable runs parallel to the handlebars and therefore matches the cable routing of the Sram Stealth brakes. There are two shift lever variants: single-click for e-mountain bikes and double-click for non-motorized bikes. Furthermore, a mechanical lever for operating mechanical dropper posts has been developed for a tidy cockpit. This integrates seamlessly into the system, is compatible with most mechanical dropper posts and offers optimized ergonomics.

Of the two rear derailleurs, however, only the Eagle 90 derailleur has a modular design, which means it can be repaired in just a few simple steps. Spare parts are easily available, ensuring long-term use.

Short is also Sram's trump card

Sram not only offers suitable cranks for the new mechanical groupset. The Eagle 90 cranksets are made of forged aluminum and are available in shorter versions up to 150 millimeters in addition to the standard lengths of 170 and 175 millimeters. While longer cranks offer a smooth pedaling feel, shorter versions reduce crank contact and improve balance and pedaling ergonomics.

The chainrings come with the proven X-Sync tooth profile, in which the 44 specific shift points of the Eagle Transmission cassette are designed to enable precise gear changes, regardless of the applied drive force. This ensures reliable mechanical shifting performance under load.

The drivetrain 90 is available both as a complete set for new bikes and for retrofitting. The groupset for an organic bike costs 699.90 Swiss francs, while the individual changer costs 199.90. While the Eagle 70 Transmission was primarily designed for the original equipment market, it is also available as an individual component. Here, the changer costs 134.90 francs, the gearshift is available for 31.90.
