Makes Cleaning Easy
- Familiarity:
- I've put it through the wringer
There's nothing worse than having to go through each cassette cog with a towel to get the grime out. My life has been made easier with this brush. True, it's not crucial to have among your cleaning supplies, but seriously, get one if you want to save yourself some time and effort!

Great chain and cassette cleaning tool
- Familiarity:
- I've put it through the wringer
I've had the same Park Tool Gearclean Brush for about 10 years now and it still does the trick. Yes, the brush bristles have seen better days, but they still work and the teeth on the back of the handle are still great for getting grime out of the rear cassette.

I've burned through a few of these. Perfectly designed for the job and priced right. Buy two.

Scrubbed the rust off my chain
- Familiarity:
- I've used it once or twice and have initial impressions
I had a chain that was starting to rust. I got some dishsoap and water used this brush to clean the chain. It worked really well! All the rust is now gone! I haven't quite figured out how to use the other toothy end on my cassette yet... I gave it 4 starts due to the lack on instructions on how to properly use the toothy end.

Brushy
If you want to get your drivetrain shiny clean, this is the brush you'll want. The super stiff bristles agitate any sort of grease and grime off your gears. Obviously in conjunction with degreaser though. I find that if you do attack a particularly greasy part, the bristles will become impregnated with grease and you'll want a new brush after that. That applies for anything though.

The Best of the Bunch
- Familiarity:
- I've put it through the wringer
I have used a number of other dedicated chain brushes and decided to buy this one again due to it being simple cheap and effective. I like that the brush has a wider profile than some others, so it sweeps a wider section of the chain. On an older one I had to superglue the brush cartridge into the handle so it would not come out, it took a minute but solved the problem. On this one it seems like a tighter fit so it should not be an issue.

Better than a toothbrush
Not sure what to say other than it is certainly tougher and scrubs harder than your average toothbrush cleaning job.

Essential tool for any home mechanic
- Familiarity:
- I've put it through the wringer
What really can be said. Picked this up as part of a maintenance build I was doing for my garage to be able to service my bike on the regular. Just like a wax scraper for the tune shop I have built for my skis and boards the chain brush is essential to any home shop. Get one today!

Must have tool!
This brush is great for cleaning chains and cassettes! I never realized how dirty they were and these bristles get it very clean. It definitely ups the bar for post-ride bike cleaning sessions.

Scrub a dub

Nice stiff bristles for getting the grime off the chain and cassette. Not great for trying to get into very tiny spots because, like I said, stiff bristles. Works great for its intended use though.

My second one!
- Familiarity:
- I've put it through the wringer
I bought this brush to replace the one I wore out. Perfect for cleaning the cogs. I use Dumonde Tech lube on the chain, which can be messy. Pedro's Bio degreaser along with the Park chain cleaner and this brush makes for a quick and thorough cleaning of the drivetrain.

Perfect

Pretty stoked on such a simple piece. I've historically been someone who doesn't keep my bike super clean. But having this brush makes scrubbing down my cassette after every few rides a quick and easy ritual.

A clean drivetrain shifts better. Clean all those little ramps on your cassette that your chain rides as it moves across the gears. You'll thank yourself on your next variable climb.

Nice to have tool to give the cassette a deep clean or quick once over. Good quality, as expected.
