Race Bottom Brackets

Measure twice, cut once! That's our advice when it comes to selecting a BMX race bottom bracket for your frame because there are two compatibility considerations when it come to choosing a bottom bracket, the type of bottom bracket shell that the frame has, and the cranks that you plan to bolt into the frame. There are 3 or 4 predominant types of bottom bracket shells that BMX race frames are manufactured with, with the smaller, youth frames of Expert XL and smaller mainly using a threaded European BB. In the Pro sized frames we see the BB86 type used by a lot of the major brands, with others utilising the BB30 type, or PF30.

If this all a bit confusing, you aren't alone, and while tried to be as detailed as possible on the BB specifications of the frames and bikes we sell here at LUXBMX, just to throw another spanner in the works, the type of cranks that you are running can influence the bottom bracket you need to select as BMX racing cranks don't have a standard spindle diameter. Again we try to provide as much information about the compatibility as possible, but if you need to check that the bottom bracket that's in your cart is the right one, then send a message to our bottom bracket support line and our BMX experts will make sure that everything fits.

Having a high-quality bottom bracket on your race BMX bike is imperative for several reasons. This component serves as the interface between your bike's cranks and the frame, and it directly affects your bike's performance and your lap times.

Firstly, a quality bottom bracket ensures efficient power transfer. When you pedal, energy is transmitted from your legs to the cranks and, ultimately, to the wheels. Any friction or inefficiency in the bottom bracket can waste your pedaling effort. A well-made, smooth-spinning bottom bracket minimizes this loss, allowing you to convert more of your energy into speed.

Secondly, durability matters. BMX racing involves intense acceleration, jumps, and landings. A robust bottom bracket can withstand these stresses and maintain its performance over time, reducing the need for frequent replacements or repairs.

Now, in addition to a quality bottom bracket, here are some other parts to consider for improving your lap times on your BMX race bike:

Chain: An optimised chain designed for BMX racing reduces friction and enhances acceleration. Ensure it's kept well-lubricated.

Crankset: Upgrade to a lightweight, stiff crankset for efficient pedaling and better acceleration out of turns.

Tyres: Invest in race-specific BMX tyres with low rolling resistance and excellent grip on the track surface. Proper tyre pressure adjustment is also crucial.

Hubs: High-quality hubs with sealed bearings reduce rolling resistance and improve acceleration.

Brakes: Lightweight, responsive brakes ensure you can control your speed and make precise stops when needed.

Handlebars (Bars) and Grips: Choose handlebars that suit your riding style and provide a comfortable grip. Grips should offer control and comfort during races.

Frame: If budget allows, consider a lightweight, race-specific frame designed for BMX racing.

In summary, a quality bottom bracket is essential for efficient power transfer and durability in BMX racing. Combine it with these performance-enhancing components to optimise your lap times and overall race performance. Regular maintenance and fine-tuning of these parts will help you stay competitive on the track.
