BMX Cranksets

What is a BMX Crankset?

BMX cranks consist of metal arms linking the bike pedals to the bottom bracket. Freestyle cranksets are crafted for durability and play a crucial role in propelling a BMX forward. Unlike race BMX bike cranks, which are constructed from aluminium or carbon fibre, freestyle cranks utilise steel or Chromoly.

What Varieties of BMX Cranksets Exist?

Freestyle BMX cranksets primarily come in three types: 1-piece, 2-piece, and 3-piece. 1-piece cranks are secured by the bearings and are typically found on beginner bikes and older models. 2-piece cranks, featuring a single crank bolt, are straightforward to install and include a spindle integrated into one of the crank arms. The 3-piece BMX crankset is the most prevalent design for freestyle BMX bikes. Although they are generally heavier, they offer greater solidity than a 2-piece set and are often slightly broader.

What is the Ideal Length for my BMX Cranks?

BMX crank arms are available in sizes ranging from approximately 125mm to 190mm, though most riders prefer lengths of 170mm or 175mm.

The choice of crank arm length hinges on personal preference but can significantly impact your riding experience. For higher speeds, longer crank arms are advisable, while smaller arms are preferable for street riding, as they enhance clearance.

Ultimately, ensuring your crankset's compatibility with your pedals and knowing your bottom bracket size is vital.
