Mountain Bike Cranks FAQs

When should I replace my mountain bike cranks?

Mountain bike cranks can wear over time due to heavy use, impacts, or repeated exposure to mud and grit. Signs that it’s time for replacement include movement between the crank arms and spindle, creaking under load, or visible damage around the pedal threads or interface. Riders who push their MTB crankset hard on technical trails should inspect it regularly to ensure safe and efficient power transfer.

Which types of mountain bike cranks does BETD offer?

BETD supplies a full range of precision-engineered Middleburn mountain bike cranks, including RS7 and RS8 models in both Square Taper and X-Type versions. Each MTB crankset is CNC-machined from aerospace-grade aluminium for a balance of lightweight performance and exceptional strength, built to handle the rigours of modern mountain biking.

How do Square Taper and X-Type MTB cranksets differ?

Square Taper MTB cranksets use a traditional spindle and bottom bracket system that’s easy to service and ideal for riders who prefer a classic, proven setup. X-Type cranksets are designed for external bottom brackets and feature a larger spindle for added stiffness and power transfer, making them a popular choice for more aggressive riding styles. Both options deliver smooth and reliable performance when properly maintained.

How do I choose the right mountain bike crankset for my bike?

When choosing an MTB crankset, consider your frame’s bottom bracket type, chainline requirements, and intended riding style. Trail and enduro riders often prefer stiffer cranks for better power transfer, while cross-country riders may prioritise lightweight performance. Our Middleburn cranks collection includes multiple crank lengths and interface types, ensuring compatibility and performance for a wide range of mountain bikes.

Are mountain bike cranks compatible with all chainrings?

Compatibility depends on the bolt circle diameter (BCD) and spider type of your crankset. Most Middleburn MTB cranksets allow for interchangeable spiders and chainrings, making it easy to adjust gearing or convert between single and double setups. Always ensure the chainring matches your drivetrain’s speed and setup before installation.

How can I install a new mountain bike crankset?

Installing an MTB crankset requires attention to detail to ensure correct fitment and smooth performance. Always clean and grease the spindle, torque all bolts correctly, and confirm that the bottom bracket bearings are in good condition. Using the proper installation tools will help prevent damage to threads or interfaces and ensure long-term reliability on the trails.

How should I maintain my mountain bike cranks?

To maximise the lifespan of your mountain bike crankset, clean it regularly to remove grit and debris, check bolts for correct torque, and inspect threads and interfaces for wear. Periodic re-greasing of pedal threads and crank bolts helps prevent corrosion and seizing, particularly after wet or muddy rides. Proper care ensures consistent performance and longevity for your MTB crankset.
