With the cyclocross season drawing to a close, the most important component for me, riding a single speed, is the freewheel cog (there are many names for it, but I’ll stick with this one for now).
When it comes to absolute reliability in a freewheel cog, White Industries is second to none.
Among the many freewheel cogs out there, why White?
It’s simple.
White freewheel cogs can be taken apart.
From Shimano and ACS to no-name manufacturers, most freewheel cogs cannot be disassembled. Sure, since they are assembled parts, you could technically take them apart if you reversed the process precisely, but the market is flooded with models that essentially reject disassembly—requiring a variety of specialized tools, using permanent fittings, or just leaving you clueless as to where to even start.
In contrast, a White Industries freewheel cog can be disassembled using only three tools:
・An adjustable wrench
・A pin spanner
・A freewheel remover
There is nothing else quite as wonderful as that.
However, the official White Industries instructions are entirely in English, which might raise the bar suddenly. So, I’ve broken down the key points into Japanese for you here.
Now, let’s start the disassembly.
1. First, remove the outer lockring.
Secure the inner part with the freewheel remover and turn the lockring with the pin spanner.
Note that the lockring is reverse-threaded, so be careful. (Turn it to the right to loosen.)
2. Next, remove the snap ring from the groove beneath the lockring you just took off using a knife or similar tool.
For tasks like this, I love using a hobby knife with the blade dulled. It comes in very handy.
This bladeless hobby knife is also useful for scraping away dirt, so it’s handy to keep in a corner of your toolbox.
3. Once the snap ring is removed, push the inner part out from the top.
4. That completes the disassembly. It’s very easy once you remember the steps.
Be careful not to lose any of the freewheel pawls and ensure they are facing the right way when you clean them.
5. Once cleaned, apply grease and reassemble in the reverse order.
Don't use too much grease, or the pawls might stop moving, so apply a moderate amount.
When putting it back together, the pawls can get caught and make it difficult to fit; try pressing while rotating it, and it should slide in smoothly.
6. Once the inner part is seated, push the seal that was on the back side back into place.
7. Go back to the front side and, don’t forget, install the snap ring. Always make sure it is properly seated in the groove.
8. Finally, tighten the lockring by turning it to the left, and you’re all finished.
How was that? It might seem confusing to read, but you’ll be surprised at how truly simple it is once you actually try it.
Whether it’s Chris King hubs or White freewheel cogs, it makes me very happy to encounter products built on the core philosophy of "taking things apart, maintaining them, and using them for a long time."
The foundation of maintenance is cleaning.
Like everything else, it all starts with making things clean.
On a weekend when it’s a bit cold and you’re hesitant to head out, why not start by cleaning your bike?
Once you’re finished cleaning, you’ll definitely want to go for a ride.
