SRAM NX Eagle Trail MX Custom Build Kit This build kit brings SRAM's entry-level NX Eagle drivetrain to a mixed-wheel setup - a 29" front wheel for roll-over and stability, paired with a 27. 5" rear for a livelier, more playful back end. The NX Eagle derailleur and shifter run 12 speeds across an 11-50T cassette, and a Descendant crankset with a 32T steel ring gives you a bit more top-end speed than you'd get from a smaller ring. SRAM Guide T brakes handle stopping duty here, running staggered rotors - 200mm up front, 180mm out back - sized for how the bike actually rides on the way down. A Race Face AR wheelset wrapped in Maxxis Minion DHR II tires front and rear, Maxx Grip up front and Maxx Terra in back, keeps grip high where you need it most without slowing you down everywhere else. An SDG Tellis dropper post with a Matchmaker-compatible remote finishes off a build that's ready to ride the day it goes together.
