20300CMm Floating Disc Six Mountain Bike Brake Disc Cycling Accessory(blacksilver )

The reinforcement of aluminum alloy bracket completely solves the problems of rivet rubbing clamp and strength. Two kinds of materials inside and outside the floating disc are connected by rivets. This connection is not and has a certain amount of , which reduces the ht transfer. CNC manufacturing, high hardness. Condition: 100 brand new Item type: Bike Floating Disc Material: Aluminum alloy inner frame + stainless steel outer frame Optional Color: black + silver, red + silver Size: Approx. 20300CMm/8in Hole distance: the center distance to the hole is 44mm/1.7in Weight: Approx. 230g  Process: CNC engraving and milling, anodizing, stamping forming The floating disc apprs 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 green position due to thermal expansion and contraction, resulting in internal tension. Generally spking, there are two kinds of materials inside and outside the floating disc, which are connected by rivets. This connection is not . 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 ht dissipation capacity is strengthened, the anti attenuation ability will be improved.
