SRAM Eagle 90 eMTB Groupset Mechanical 10-52T Cassette GX Chain 34T Chainring

The SRAM Eagle 90 Groupset Emtb redefines mechanical shifting for electric mountain bikes, delivering reliable performance and durability tailored for the rigors of e-mountain biking. Built on the robust Full Mount derailleur architecture shared with SRAM's AXS Transmission line, this groupset ensures long-lasting strength and rebuildability with replaceable outer and inner parallelogram links, skid plates, and a tool-free threaded cage assembly. Its engineering caters specifically to eMTB riders who demand smooth, precise shifting even under heavy load and challenging terrain.

Designed for seamless integration with Hangerless Interface (UDH) frames, the Eagle 90 Groupset features a sleek black and silver finish, exuding both style and resilience. The groupset includes a 34T 104bcd T-Type chainring without crank arms, providing compatibility with various drive unit manufacturers. The accompanying GX T-Type chain with solid pins is fully approved for eMTB use, ensuring durability and smooth chain movement. The XS-1275 T-Type cassette offers a wide 10-52T gear range with advanced X-SYNC technology, enabling crisp and reliable shifts regardless of conditions.

Shifting is handled by the premium double-click T-Type mechanical shifter, designed with modern ergonomics and a textured aluminum lever for comfortable and precise control. The Eagle 90 shift lever boasts stealth architecture and MMX compatibility, allowing seamless pairing with SRAM brakes and maintaining a tidy cockpit with the included Shift Housing/Brake Hose clip. This groupset's simple four-step setup process—Prepare, Hang, Tighten, Route—eliminates guesswork, limit screws, and B-tension adjustments, making installation straightforward even for DIY enthusiasts.

What It’s Good For

• Reliable and precise mechanical shifting optimized for eMTB riding conditions.
• Robust and rebuildable derailleur with replaceable components for extended service life.
• Wide 10-52T gear range cassette with X-SYNC technology for smooth, consistent shifting under load.
• Compatibility with UDH frames and multiple eMTB drive units thanks to versatile chainring options.
• Ergonomic and tactile double-click shifter designed for comfortable control during intense rides.
