Shoulder knobs are proportionally taller than the standard Grappler for a smooth, predictable lean transition. It's a purpose-built rear tread for Enduro, DH, and E-MTB riding.\u003c\/p\u003e\n\n\u003cp\u003eThe Flux GR Radial casing adds radial ply construction, which lets the tread and sidewall flex independently. The result is a rear tire that tracks straighter under braking, conforms better to rough terrain, and reduces fatigue over long stages. The 72 TPI dual-ply construction with Dual Apex inserts on each sidewall keeps the tire stable under hard cornering loads without fighting the radial compliance.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in two purpose-built compounds:\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMoPo\u003c\/strong\u003e is a pure 42a single compound designed for maximum grip.
