What Our Gearhead® Experts Are Saying:

"The Eagle 90 T-Type DUB Groupset delivers mechanical shifting like nothing else. The Full Mount derailleur design makes it ultra-durable, while the 10-52T cassette ensures a massive range for technical climbs and high-speed descents. The GX Eagle Flattop chain and X-Sync cassette provide smooth, precise shifts—even under max power. It´s the ultimate choice for riders who want top-tier performance with the reliability of a mechanical drivetrain."

Shifting should be simple, powerful, and ultra-reliable—that’s exactly what the Eagle 90 T-Type DUB Groupset delivers. With a Full Mount derailleur design, it clamps securely to the frame for rock-solid shifting and unmatched durability, eliminating the need for traditional hangers and reducing adjustment hassles. Whether we’re grinding up technical climbs or hammering through high-speed descents, the XS-1275 T-Type Cassette’s 10-52T range gives us the gears we need, when we need them.

Paired with a GX Eagle Flattop Chain, every shift is crisp and efficient, even under full power. The Eagle 90 T-Type Shifter offers responsive actuation with an optimized cable pull, delivering a smooth, intuitive ride feel. And with a forged aluminum crankset designed for maximum strength, we know every watt we put down is going straight into the trail.

For those of us who demand top-tier performance without the complexity of electronics, the Eagle 90 T-Type DUB Groupset is the future of mechanical shifting.
