BSD GUARD BMX SPROCKET 28T BLACK
67.90 €
Freestyle BMX sprocket commonly comes in two main attachment systems known as SPLINE DRIVE and BOLT DRIVE. Spline drive is a system where the sprocket slides onto a 48-spline crank spindle. The connection to the cranks is very secure, but this system can only be used with cranks featuring a round, 48-spline spindle. A much more commonly used system is BOLT DRIVE, where the sprocket is fastened to the crank using a bolt. It's a simple and proven method over the years.
Spline drive is a more modern and relatively widespread trend in attachment. The sprocket slides directly onto the 48-spline cranks and provides a reliable connection. However, this system can only be used with cranks featuring a 48-spline spindle.Bolt drive is an attachment system using a bolt that tightens through the sprocket from the inside of the crank. This system can be used on all cranks labeled as 'bolt drive'.
Sprockets with hub guards are recommended for street riders who do a lot of grinding and need to protect their chain from damage during grinds or falls. Manufacturers offer sprockets with guards, either as separate plastic pieces or as integrated solid castings that are part of the sprocket itself.
NUMBER OF TEETH
Sprockets for BMX come in various tooth counts. The most common choices are 25 teeth and 28 teeth. For park and street riding, 25 teeth are recommended. For dirt and trail riding, a sprocket with a higher tooth count can be preferred. For those who love grinds, it's advisable to use a sprocket with a protective guard to ensure chain safety.
SPROCKET THICKNESS
Sprocket thickness determines its strength and its ability to withstand bending forces. The standard thickness is around 5mm, which should be suitable for typical freestyle BMX riding.
