| Message: | 1.Xiamen City Bola Sports Goods Co., Ltd. are one of the leading wheelset manufacturer in China. The introduction of company is following:5. To buy a set of carbon track bike wheel, we must consider several characteristics: weight, strength, aerodynamics, smoothness, braking performance, durability, and convenience. Lets take a look at these features.1: Weight: A: Simple wheel weight is only a static pointer reference, which is more valuable for climbing. Generally, the preferred front drum has a weight of about 80-110gm, the rear hub is 200-270gm, the steel wire is about 9-12gm, and the rim changes greatly. The pure carbon fiber is about 210-300gm (narrow frame) 280-420gm (large frame) ), aluminum frame 350-500gm, wire head, aluminum about 0.5g, copper 1gm. The whole group weight is more common between 1100-1800gm. B: Relative rolling weight: It is important. Imagine the chain ball is clearer, a one kilogram of chain ball, the chain is rotated one meter to rotate, the power required to turn it up, is proportional to the weight and chain length. The same is true for the carbon track bike wheel, but the weight distribution of the carbon track bike wheel is not as simple as a chain ball. The distribution of steel wire and rim is from the inside to the outside, but the proportion of the wheel and the tire is the largest. Because of its outermost edge, the weight is also the highest. The rotating weight of the hub is hardly considered..Xiamen City Bola Sports Goods Co., Ltd. has over 10 years experience to export our products to almost all over the world. Our main market is North America,South America,Western Europe,Eastern Europe,East Asia,Middle East,Oceania, and we still constantly expanding new markets.x31645dan
