Chances are good that your bike came with a D.I.D. chain when it was new - manufacturers know the reliability and consistency of D.I.D. brand. But since your bike was new, technology has moved forward... O-rings have been replaced in DID chains, by X-Rings, for half the power loss and longer life!
One Clip-type master link is included
Spare master links are available in:
Rivet-type or Clip-type
Gold or Grey colour
Half the Power Loss (Compared with Normal O-Ring)D.I.D's PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers' modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss.
1.5 to 2 Times Longer Wear Resistance (Compared with Normal O-Ring)The X-Ring's four contact points greatly increase its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain.
