LifeLine Shimano XTR-XT-Saint M800-SLX-LX Pads - Copper - Organic}, Copper
  • £4.99

LifeLine Shimano XTR-XT-Saint M800-SLX-LX PadsLifeline's A-Type Shimano XTR and XT compatible brake pads provide excellent stopping power and their design shields the brake caliper from heat build-up, ensuring fade free performance on long descents. They're available in two compound types; Organic for urban, Cross Country and short Downhill courses, and Sintered for longer distance Enduro, All Mountain, and Cyclocross use.Strong Braking PowerThe Organic compound provides a strong initial bite and a reduced bedding in period, making it suitable for riding where generally lighter force is needed, or for one-time race use on Downhill riding.Fade-Free Braking PerformanceThe Sintered compound may not provide the same initial bite and need some time to warm up to work at their best, but it performs better in wet weather conditions as the metal compound is not affected by mud and water. It’s also much more durable and provides longer fade-free performance on long descents, making them ideal for longer distance riding.Features: Compatibility: Shimano M965, M966, Saint, M800, SLX M665, Deore M535, M585, M601, M665, M765, M775, M965, M966, M975; Tektro Dash, Parabox Both compounds provide excellent stopping power Available in Organic or Sintered compoundsClick HERE for compatibility chart.Buy LifeLine Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
