Shimano DXR Crankset

The DXR is specifically engineered for high-intensity disciplines like BMX racing, pump tracks, and dirt jumping. Its construction prioritizes structural integrity and power transfer, making it ideal for riders who need a crank that can handle aggressive maneuvers and heavy impacts.

No, the DXR crankset does not include a bottom bracket. It utilizes an outboard bottom bracket interface with a 24mm spindle, so you will need to purchase a compatible Hollowtech II bottom bracket separately.

The DXR is designed for threaded bottom bracket shells with widths of 68mm or 73mm. While it is built for BMX racing, it can be compatible with some mountain bike frames, provided they use a standard threaded shell and you have the correct spacing.

The steel pedal insert is included to prevent the pedal threads from stripping over time. Because this crankset is built for high-impact riding, the steel insert provides a much more durable interface than aluminum alone, ensuring your pedals stay secure even under heavy load.

A narrower Q-factor places your feet closer together, which can improve pedaling efficiency and provide a more natural, ergonomic feel. This is particularly beneficial for track and BMX riders who need precise, rapid power delivery.

The Hollowtech II construction allows the crank arms to be hollow-forged, which significantly reduces weight without sacrificing stiffness. This balance is critical for rapid acceleration and maintaining responsiveness during technical riding.
