{"product_id":"ks-d640s","title":"Sintered Shimano Zee\/Saint Disc Brake Pads","description":"\u003cp\u003eThe KOOLSTOP KS-D640S is a sintered disc brake pad engineered for demanding conditions, compatible with Shimano XTR, Deore M9120, ZEE, and Saint systems. Built with a copper-plated backing plate and sintered compound, these pads are selected for riders who push hard on steep descents, technical trails, and unpredictable surfaces — exactly the kind of riding you find on the Western Ghats and Himalayan routes around Leh.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eIndia's mountain trails — from the switchbacks above Ooty to the loose-gravel descents near Manali — demand brake pads that resist fade under sustained pressure. The KS-D640S sintered compound bites consistently even when wet, which matters enormously during Kerala and Konkan monsoon riding. The copper-plated backing plate adds heat dissipation that keeps performance stable when temperatures climb past 35°C on long valley descents. For aggressive trail and enduro riders, this is a dependable, well-specified choice.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eDisc brake pads are not sized by body measurement — fitment depends entirely on your brake caliper model. Confirm your brake is Shimano XTR, Deore M9120, ZEE, or Saint before ordering. These are also noted as Tektro G-Spec compatible. Double-check your caliper code against the KS-D640S compatibility list to avoid fitment issues before your next Coorg or Lonavala trail weekend.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eCompatible with Shimano XTR, Deore M9120, ZEE, and Saint disc brake calipers, as well as Tektro G-Spec systems.
