Bmx Bikes Racing Details
BMX bike or BMX is the name of a popular bicycle used for both casual use and sport, and designed mainly for dirt and motocross cycling. "BMX" is the usual abbreviation for bicycle motocross.
Though
originally denoting a bicycle intended for BMX Racing, the term "BMX
bike" is now used to encompass race bikes, as well as those used for the
dirt, vert, park, street, flatland and BMX freestyle disciplines of
BMX. BMX frames are made of various types of steel, and (largely in the racing category) aluminum. Cheaper, low end bikes are usually made of steel. High range bikes are mostly chromoly
or high tensile steel, although the latter is noticeably heavier with
respect to strength. High-performance BMX bikes use lightweight 4130
chromoly, or generation 3 chromoly.The introduction and widespread popularity of the cassette hub has ushered in the use of smaller gearing on BMX bikes. Instead of the old 44/16 gearing found on almost all older BMX bikes, new bikes use gearing such as 36/13, 33/12, 30/11, 28/10, 25/9, 23/8,and even 22/8, all of which have similar gear ratios of almost 2.8:1. Advantages of smaller gearing hubs include lighter weight, and more clearance when grinding. The freewheel hub is all but extinct due to several factors. The smallest freewheels that can be made is with 8 teeth, which is smaller than most riders prefer. Also, they are less consistent than cassette hubs, and skip or jam up far more frequently.
