BMX Frame Parts
Good to know
BMX Race Frames Are Lightweight for Top Speeds
To get the most out of your BMX racing experience, you should have a frame that is light, stable and is appropriate for your height. In a BMX race, the goal is to cross the finish line before everyone else and to do this, your BMX race bike frame needs to give you control when you are riding at high speeds and taking tight turns.
What Size of BMX Race Frame Do I Need?
Within the BMX race frame category, you will see they are divided up into “frame names” starting with Mini and going all the way up to Pro XXXXL. The two main measurements that divide the frames are the top tube length and chainstay length. Generally speaking, these lengths both increase as the frame size gets bigger.
Top tube length is the distance between the centre of the head tube and the centre of the seat tube. The goal here is to have a length where you can ride in a comfortable and athletic position. Your own height is the primary indicator, so check out our BMX Race Size chart to see what length we recommend for your height.
Chainstay length is measured from the rear axle to the centre of the bottom bracket. The length of the chainstay affects whether your BMX bike will have a longer wheelbase or shorter wheelbase. The longer it is, the more stable the bike will be when jumping and going at speed. The shorter chainstay will make the frame more agile and easier for manuals and sharp turns.
BMX Headtube Angle
The headtube angle is another detail to consider that can affect the overall feel of the bike. Between 74 - 76 degrees is where most BMX frames have their headtube angle, but it can vary outside this. Moderate angles (74 or lower) create a longer distance between the wheels, while the steeper angles (76 or higher) bring the wheels closer together.
Another part of a race BMX bike that can greatly affect the overall feel is the handlebars. To see our collection, check out Race BMX Handlebars.
