Mountain Bike Brake Disc, 203mm Bike Disc Brake Rotor with 6 Screws Fit for Road Bike Mountain Bike

Specification:Condition: 100% brand newItem type: Bike Floating DiscMaterial: Aluminum alloy inner frame + stainless steel outer frameOptional Color: black + silver, red + silverSize: Approx. 203mm/8inHole distance: the center distance to the hole is 44mm/1.7inWeight: Approx. 230g Process: CNC engraving and milling, anodizing, stamping formingThe floating disc appears to solve the problem that after the continuous friction temperature rise of the integrated disc, the temperature at the center of the disc is different from that at the edge green position due to thermal expansion and contraction, resulting in internal tension.Generally speaking, there are two kinds of materials inside and outside the floating disc, which are connected by rivets. This connection is not rigid. The thermal attenuation is related to the high temperature resistance of the material, and the floating disc will not reduce the thermal attenuation. However, if the disc material and design are optimized and the heat dissipation capacity is strengthened, the anti attenuation ability will be improved.Package List:1 x Mountain Bike Brake Disc6 x Screw

• For : 2 different colors for you to choose, meet your different needs. Suitable for mountain road bike disc brake systems with 6-Screw hubs
• Aluminum Alloy Bracket : The reinforcement of aluminum alloy bracket completely solves the problems of rivet rubbing clamp and strength. long pad life, less noise, less fade and light weight
• Connected by Rivets : Two kinds of materials inside and outside the floating disc are connected by rivets. This connection is not rigid and has a certain amount of free, Better heat dissipation means consistent, dependable braking performance even during long descents
• Process Design : CNC engraving and milling, anodizing, stamping forming. CNC precision manufacturing, high hardness.
• Button Design : Stainless steel floating button design, so that the outer dish is not directly locked with the hub, leaving expansion space.
