How to choose the right race BMX frame
Selecting the size for a new race BMX frame is mainly based on personal preferences. Here are a couple of tips that can help new and inexperienced riders choose the right size.
When racing you will obtain high speeds on the track, it is therefore often an advantage to have a longer frame, since it provides a more stable experience on the track.
The increased stability allows you to go faster without losing control. If you wish to have a more responsive race BMX, a shorter top tube will allow you to aim better for the right lane in the turns.
Should i go steep or flat on the headtube angle?
The angle of the headtube is another important part of the stability on a race BMX. A flat angle gives the bike a longer wheelbase. A long wheelbase gives the bike more stability at high speed. A steep angle makes the bike shorter and more responsive. The flat angle is usually preferred by race BMX riders because it provides better control on the track.
What chainstay length should i choose?
While talking about responsiveness versus stability of the race BMX frame, the chainstay length (the rear end of the BMX frame) is another thing to consider. The chainstay length on a race BMX is in the range from 12 to 16 inches depending on the frame.
Most race BMX riders prefer a longer rear end since it offers more control. On the pump track a long rear end will allow a harder pump without the bike flipping backwards.
Light-weight Race BMX frames
The theory about race BMX is that lower weight allows more speed. With the lightweight as a goal, most race BMX frames are produced in light materials - typically either carbon or aluminium. The lightest race BMX frames are usually made of carbon - but the heaviest if you look at the price.
