Bicycle Cranks FAQs

How do I know if my bicycle cranks need replacing?

If you experience creaking, noticeable play in the crank arms, or visible wear on the crank arms or spindle interface, it may be time to replace your cranks to maintain safety and performance.

Which bicycle cranks does BETD sell?

BETD offers a range of high-quality Middleburn cranks, including the RS7 and RS8 models in both Square Taper and X-Type variations. We also provide the RO1 and RO2 cranks, designed for road, mountain, and tandem bikes, as well as trials guards for added protection and durability. For tandem riders, we stock specialised cranks engineered for optimal power transfer.

What is the difference between Square Taper and X-Type cranks?

Square Taper Cranks, such as the RS7 and RO1, attach to a traditional square taper bottom bracket and are known for their durability and ease of maintenance. X-Type Cranks, such as the RS8 and RO2, use an external bottom bracket, which provides increased stiffness and better power transfer, making them ideal for performance-oriented riders.

How do I choose the right crankset for my bike?

Choosing the right crankset depends on factors such as your bottom bracket type, riding style, and bike setup. If you are unsure, it is best to check the specifications of your current crank or contact our team for expert advice.

Are bicycle cranks compatible with all chainrings?

Middleburn cranks are designed to work with specific chainrings, so it is important to check the Bolt Circle Diameter (BCD) and ensure compatibility before purchasing a new chainring.

How do I install new bicycle cranks?

The installation process depends on the type of crankset. Square Taper cranks require a crank puller tool for removal and a bottom bracket wrench for installation. X-Type cranks are installed using external bottom bracket cups and typically require an 8mm or 10mm hex key. If you’re unsure about the installation process, it is recommended to seek professional assistance.

How should I maintain my bicycle cranks?

To keep your cranks in optimal condition, regularly check and tighten crank bolts to prevent loosening. Inspect the crank arms and chainrings for any signs of wear or damage, and clean and lubricate the bottom bracket interface to ensure smooth performance.
