Chain Stay Length
Chainstay length is the distance from the centre of the bottom bracket to the centre of the rear axle. This length is important to consider when choosing a frame because it changes the way your bike will react in different situations. The standard chainstay length on BMX bikes is between 12.8-14 inches. Street and park frames are leaning towards a short more “snappy” back end. The shorter the back end the closer the bike is together allowing the rider to spin, hop and manual easier. Longer back ends aim to give more clearance for the rider missing their back peg, however, the longer the chainstay length the more resistance the rider will feel when trying to manual.
