Crank Spares FAQs

Are your crank spares compatible with all brands?

The crank spares available on our site are primarily designed to fit Middleburn
cranksets, which feature specific interfaces and dimensions. While some items may be compatible with other crank brands, we always recommend checking product specifications or consulting our team if you're unsure. Using the correct spares ensures a precise fit and avoids potential damage to your crankset or drivetrain.

What is a self-extracting crank bolt and do I need one?

A self-extracting crank bolt is a crank removal system that eliminates the need for a separate crank puller tool. It consists of a bolt and a cap that work together to press against the crank arm as you unscrew the bolt, safely pushing the crank off the spindle. This system simplifies maintenance and is especially useful for riders who frequently service their own bikes. Many Middleburn cranksets are compatible with this feature, making it a convenient and user-friendly option.

How do I know which crank bolt or cap I need?

The correct crank bolt or cap depends on the model of your crankset and the type of bottom bracket you’re using, such as square taper or external (X-Type) setups. Middleburn cranks use specific bolt sizes and threads, so it's important to match the spare to your crank model. If you're not sure which part you need, you can refer to your original crank documentation or contact us for guidance with details about your setup.

Can I use Middleburn crank spares with older crank models?

Yes, many Middleburn crank spares are backwards compatible with older crank models, including legacy RS7 and RS8 systems. We stock a wide range of spare parts to support riders still using these proven cranksets. However, due to design updates over time, we recommend confirming compatibility for specific items, especially bolts and caps, which may have changed in design or threading.

What is the purpose of crank spacers and how are they used?

Crank spacers are small rings used to fine-tune the chainline and crank arm clearance during installation. They are placed between the crank arm and bottom bracket or spider to ensure proper alignment and to prevent rubbing against the frame or drivetrain components. Proper use of spacers ensures efficient power transfer and helps avoid premature wear on other components.

Do you stock replacement extractor caps for Middleburn cranks?

Yes, we offer replacement extractor caps specifically designed for Middleburn
cranks. These caps are essential for self-extracting systems and should be installed properly to prevent damage during crank removal. If your original cap has become stripped, damaged, or lost, we provide exact fit replacements to restore full functionality to your crankset.

Can I get help choosing the right crank spares for my setup?

Absolutely. Our team is happy to assist you in selecting the correct crank spares for your specific bike and crank model. If you’re unsure what you need, just get in touch with your crankset details, and we’ll point you in the right direction. We want to ensure you get the right part the first time to keep your bike running smoothly.
