X1\'24 Graphite Chassis 2.5mm with side braces, gives additional flex control along with 2 additional positions for servo mounting in forward/rearward positions and a hole for the aluminum top-deck mount & battery backstop. The super-narrow chassis creates maximum traction while still having excellent steering and cornering speed. The chassis’ torsional stability also helps to eliminate the “scrub effect” in high-speed corners. Machined from premium high grade carbon fiber material.
