Bicycle Spiders FAQs

What makes Middleburn spiders unique?

Middleburn spiders are precision-engineered in the UK and are known for their high quality, lightweight aluminium construction. Designed for durability and performance, they are compatible with our range of modular Middleburn cranks, allowing riders to easily swap out chainrings or change configurations without needing to replace the entire crankset. This flexibility makes them a favourite among riders who demand customisation and long-lasting
performance.

How do I know which spider fits my crankset?

To determine which spider you need, you’ll need to check the model of your crankset and confirm the bolt circle diameter and spline fitting. Middleburn spiders are designed specifically for Middleburn crank arms, so it’s important to match the spider to your crank model to ensure a secure and proper fit. If you’re unsure, you can contact our team with your crank details and we’ll help you choose the right option.

Can I change the chainring size with a different spider?

Yes, one of the benefits of using a modular spider system is the ability to change chainring sizes to suit different terrain or riding styles. By selecting a spider with the appropriate bolt circle diameter, you can fit larger or smaller chainrings as needed.

Are Middleburn spiders compatible with other crankbrands?

Middleburn spiders are primarily designed to work with Middleburn cranksets, particularly the RS7, RS8, and RO series. While some riders have modified them for use with other systems, we recommend using them with their intended cranks for the best fit and performance.

What are the different types of spiders available?

Spiders come in different configurations based on the number of chainrings you want to run, such as single, double, or triple setups. Middleburn offers various spiders including single ring spiders for 1x setups, double spiders for 2x drivetrains, and triple spiders for those needing a wider gear range. The choice depends on your drivetrain, terrain, and riding style.

Do spiders affect bike performance?

While the spider itself does not directly affect speed or power, it plays a key role in drivetrain stiffness and chainring alignment. A well-designed spider ensures efficient power transfer and precise chainring positioning, which contributes to better shifting and smoother pedalling.

How do I install or change a spider?

Installing or changing a spider involves removing the crank arm from your bike, unbolting the existing spider, and attaching the new one using the appropriate torque settings. Bicycle spiders attach to the crank via a spline interface and are secured with bolts. It’s important to follow proper installation procedures to ensure a secure connection and optimal performance. If you're unsure, a professional mechanic can assist with the installation.
