SRAM Eagle 90 Maven Build Kit - OE Packaged The full Transmission experience, with cable-actuated simplicity. SRAM Eagle Transmission introduced a durability revolution to the mountain bike world, and this mechanically-actuated Eagle 90 Transmission kit makes the Transmission world accessible without the need for wireless electronic shifting. This Jenson USA Exclusive complete build kit pairs the Eagle 90 Transmission drivetrain with the already-legendary SRAM Maven Base hydraulic brakes, as well as a SRAM Dropper Lever for a cohesive build kit for virtually any MTB. The Eagle 90 derailleur uses the same Full Mount design as SRAM's T-Type siblings, with a new cable actuation ratio that delivers the most precise mechanical shifting the platform has ever seen. The XS-1275 cassette provides a 520% range with optimized low-end steps, the GX Eagle Flattop chain is the strongest SRAM has ever built, and Maven Base's four 18mm pistons with Direct Link lever action deliver extreme-duty power that stays consistent from the first corner to the last.
