The BMX Frame is the biggest and most important part of your bike. Due to all of the geometry and sizes involved, a frame can make one bike feel completely different from another. If you haven’t given our BMX Frame Geometry Guide a look, we highly suggest it. The angle of the head tube and seat tube, top tube length, standover height, bottom bracket height, chainstay length and more are all very important details when deciding on the frame that is right for you. Some are designed for street, some for ramps, trails or flatland. Others can be ideal for riding a little bit of everything. It all comes down to the rider and their personal choice on geometry, size, color and more.

The BMX handlebars are another part of the bike that you have plenty of options for when it comes to sizes, geometry, colors and features like 2-piece or 4-piece. Having the right bars can make your bike feel better, allow you to do different tricks easier, have more control and even keep your back or wrists from hurting. We definitely suggest you check out our BMX Handlebar Geometry guide.

The BMX Fork is a part on a BMX bike that you have to put a lot of trust in and having the right one is very important. The fork takes a lot of abuse and you don’t want it snapping on you when you’re coming down from a trick. Choosing the fork with the right features for your style of riding is important. The different features like Investment Cast dropouts, offset, taper and butting of the tubing, heat-treating and more are all different things to consider when purchasing a BMX fork. Having a fork you can trust to hold up to everything you throw at it is a must!

Having the right BMX Stem can also help with the overall look and feel of your bike. Do you prefer top load, front load or a drop down stem? Do you want something that’s sturdy and solid, or are you looking to shave a few ounces with some additional machining? Reach, rise, stack height and more can all adjust the feel of your bike, so knowing what you like is important. These days, a topload stem mixed with a taller set of bars are very popular.

The difference between a quality BMX bike and a cheaper bike can easily be spotted in the headset. Does your bike use an Integrated head tube with a sealed Integrated headset, or does it use a Standard size head tube with headset cups that need to be pressed in and loose ball bearings? The Integrated head tube and headset are the standard for BMX bikes.
Here’s a look at a few HEADSETS!
There are a lot of BMX Grips out there and it all comes down to personal preference. The hardness of the rubber, the design and style, length, flanges or flangeless and colors are all options to consider.

When it comes to BMX Pedals, there are a lot of options for riders with plastic, or PC (Polycarbonate), pedals that are usually made from Nylon, or metal, which are usually made from 6065 or 7075 aluminum. A rider will usually choose a pedal based on material, followed by shape, grip, color options and type of bearings (sealed versus unsealed). Plastic pedals tend to be less expensive and a little friendlier on the shins, but they do wear down faster. Metal pedals offer superior grip and will last much longer. You can also find sealed bearings in some metal BMX pedals. If you like plastic, but also like the grip of metal pedals, you can also get some plastic pedals with replaceable metal pins.

Another part that has a lot of options to choose from are BMX Cranks. Traditionally BMX cranks feature a 3-piece design that has two crank arms and a spindle. There are some that utilize a 2-piece or a 2.5-piece design that has one of the arms and spindle attached, eliminating one of the bolts holding the arms on to the spindle. The 2-piece system simplifies the installation process and saves weight. BMX cranks are available in three spindle sizes, 19mm, 22mm and 24mm. The larger spindles offer additional strength that are more ideal for street riding because of the heavy landings and harder abuse than somebody like a ramp rider that tends to land smoother with transitions. Most BMX cranks come with a 48-spline spindle, which also allows you to run a Spline Drive BMX sprocket that eliminates the bolt that holds the sprocket in place. BMX cranks also come in a number of sizes, for freestyle 160mm, 165mm, 170mm, 175mm and 180mm are common. You can learn more about how the length of the crank arm effects your bike here Profile Racing – Tech Tip: BMX Crank Arm Size.

As we mentioned above with the cranks, BMX Sprockets are available in a number of sizes and styles. The most common sizes of BMX sprockets for freestyle BMX are 25-tooth and 28-tooth, but other sizes are also available. BMX sprockets usually come with a 24mm bore, with 19mm and 22mm adaptors to fit the different BMX crank spindle sizes. There are three styles of sprocket holes; standard which requires a bolt to hold the sprocket to the crank arm, Spline Drive which allows the sprocket to slide onto the 48-spline spindle, holding the sprocket in place and eliminating the bolt and Socket drive, which is similar to Spline Drive but uses a hexagon shape to hold the spindle on the cranks. Socket Drive is not as common as the other two styles. Another thing to consider with BMX Sprockets are if you want a guard or not to protect the chain from grinding. There are three styles of sprockets; no guard, which is the lightest option that leave the teeth exposed, full guard which features a guard that wraps around the entire sprocket protecting the teeth and half-guard which uses a removable guard that only covers a portion of the sprocket saving weight. The full guard is usually integrated with the sprocket, but some do come with a removable guard as well.

The BMX Chain is another part that you will want to invest in quality because cheaper chains tend to break more frequently and that usually leads to crashing and smashing your knee into your stem. The standard BMX chain comes in a 1/8″ size with full size and half-link styles. Some riders swear by half-link chains like The Shadow Conspiracy’s Interlock chain and others believe full-link chains are stronger. The biggest benefit to half-link chains is the adjustability that you have in the dropouts on your frame, allowing you to find the perfect spot for your wheel. Many full-size chains also come with a single half-link pre-installed to also give you that adjustability. Things like thicker side plates and heat-treated pins can greatly improve the overall strength of a chain.

When it comes to BMX seats you have plenty of options for styles and sizes. There are four main styles of BMX seats; Pivotal, Tripod, Combo and Railed. The Pivotal style seat comes in two versions as well; regular where the bolt comes in through the top, or Stealth which brings the bolt in through the bottom giving you a cleaner look up top. Pivotal seats offer more adjustability in angle with multiple teeth allowing you to set your seat to an angle most comfortable to you. The Tripod seat is simplified and lightweight using one small bolt to hold the seat in place. The downside to Tripod is that it offers only two angles. Combo seats are a seat and post all in one, which offers only one angle since everything is one piece. Railed seats aren’t as common these days due to weight and complexity of installation. The railed seat does offer the most adjustability allowing you to adjust the angle of the seat up and down, and move the seat forward and backwards. BMX seats also come in slim, Mid and Fat versions for padding. You can find many colors, styles and materials used on BMX seats from leather to fabric and Kevlar.

Like we mentioned above with BMX seats, there are also four styes of BMX seat posts to match the seats. There are the Pivotal posts with small teeth, Tripod with two hooks and a bolt hole, combo which the post and seat are combined and railed which uses a clamping system to pinch the rails of the seat in place. There is also the Stealth Pivotal seat posts that use the Pivotal style seat, but bolt into place from below.

The final piece to BMX seats, the BMX Seat Post Clamp which holds the seat post at your designated height and the seat straight forward. Seat post clamps are commonly found built in, or “Integrated” with BMX frames, eliminating the need for a separate clamp. Some BMX frames do not come with a seat post clamp built-in to help keep the overall price of the frame down, so you will need a clamp in that case.
