NEED NEW BEARINGS
After a thorough service (check: How to Service Bearing), if the bearing is still running rough and noisy, it’s time to purchase new bearings.
​We will provide you with the details on how to select the correct bearings for your bike’s bottom bracket, wheel hub, pulley wheels, and headset.
BOTTOM BRACKET
There are so many different bottom bracket standards out there, which cause a lot of confusion, but at the root, there are only a few sizes/types of bearings used.
However, it is not ideal to just replace the bottom bracket bearings themselves, as the problem is that, even though standard-sized bearings are used, each brand of bottom bracket manufacturer has their own matching housing that works best for their chosen bearings. If you replace them with different bearings in those housings, they may not perform as well as before.
And due to the different engineering process and structure, replacing bottom bracket bearings is often lots harder than replacing the entire bottom bracket itself.
Hence, we suggest replacing the whole bottom bracket unit for a brand new fresh start.
WHEEL HUB
It has always been a challenge to identify which bearings are in your wheel hubs.
Trust us, even the same model of the wheel, depending on the year of build and region of sale, can have different bearings inside the hub. So never assume.
Check with us first, for some models, we can tell straight away if you provide some photos of the hubs.
​
The good news is that only a few common bearings are used in the majority of bike wheels on the market, and you can pretty much find all of them here.
PULLEY WHEEL
The most common bearing used in a bike rear derailleur pulley wheel is the 688 (inner diameter: 8mm, outer diameter: 16mm, width: 5mm).
In pulley wheel situations, the wheels usually wear out faster than the bearings themselves. Hence, the need to replace the bearings in pulley wheels is very rare. Instead, replacing the pulley wheels provides a fresh start.
HEADSET
Headset bearings play a crucial role in your bike's steering performance.
Over time, headset bearings can wear out or become contaminated, requiring replacement. Here's a comprehensive guide to understanding bike headset bearings and finding the right size for your replacement.
