Bike Bottom Bracket Components for Cyclists

To prevent uneven surface-induced shaking, this washer can be used as a BB spacer. It helps fix the chain line on a fixed-gear bike by ensuring the chain does not rub against the tire. This allows for the maintenance of a proper chain-line. Additionally, it can be used to add a small amount of spacing to a mid-drive motor, making it a versatile solution.

These shims are also great for replacing spacers between cogs. They provide perfect alignment, eliminating the need for derailleur adjustment when switching to a wheel with a 9-speed cassette on a 9-speed hub. This feature simplifies the process of swapping wheel sets, as it allows you to do so without having to readjust the rear derailleur.

The ease of use and installation is another key benefit of these shims. They enable your crank arms to rock side-to-side effortlessly, and the entire process of removing the crank and cup, installing the spacer, and rebuilding the assembly only takes around 10 minutes.

Furthermore, these shims ensure smooth shifting with no play, and they do not catch on the backstroke. This translates to a seamless and reliable shifting experience, enhancing the overall performance of your bicycle.

In summary, this versatile washer/spacer offers several advantages for both fixed-gear and multi-speed bike setups. It helps maintain proper chain-line, prevents shaking from uneven surfaces, simplifies wheel set swaps, and provides a quick and easy installation process. Whether you're looking to fine-tune your mid-drive motor, replace worn-out spacers, or ensure smooth, hassle-free shifting, these shims can be a valuable addition to your bike maintenance toolkit.
