Grunge Brush Bike Chain & Gear Cleaner – Dual-Sided Bristles for Chains, Cassettes & Hard-to-Reach Areas

Simple and effective. I don't like reusing master links over and over and this tool is a great help in decreasing/cleaning y out r drive train without having to remove the chain.

Are you looking for a tool to clean your chain, but you cannot find a quality tool in your budget? Look no further! I introduce to you... the Grunge Brush! Okay I'm done sounding like a commercial. This is just as good as those fancy tools that you see for like $40- $50 (for a quality one, not a cheap Chinese version that will last 2 seconds). It is somewhat difficult to get the chain in, but that tells me how well it's cleaning my chain! The brush on the end is perfect to clean you're cassette. Just spray some drivetrain cleaner on the cassette (not brakes unless you want to clean those too) and brush it then rinse with water.

Easy to use and cleans the chain great. rinsed clean after usr.

To tell you the truth , I accidentally ordered 2 of these . I goofed up. I only wanted one . My bad 🤷🏼‍♂️😖....I was going to return the second one. But after I actually used one of them I liked it so much I decided to keep them both . 👍🏻👍🏻... These work well on size #35 chain ,like on go karts or MINIBIKES . Very tiny chains. While these cost more than the sea of cheap Chinese crap available on Amazon , they are built so much sturdier Than the cheaper junk . Very nice . I highly recommend these and the seller was super fast 😊👍🏻👍🏻👍🏻👍🏻👍🏻

Did everything I wanted it to do. It gets my chain cleaner than ever

The tail brush isn’t as firm as I would like but it’s still good

It's useful, but was hoping it would behave a little more like a chain cleaner tool. That's not a fair comparison though. I guess I let my chain get to dirty because this brush doesn't clean it well and gums up... this is probably a user error, but thought that people might like to know that it's not a miricle product and you really do need to wipe your chain down between cleanings.

Works great with degreaser solutions to clean chain and cassettes. Easy to hold and apply force. Brushes are durable.

Boa qualidade e prático

Das Tool bekommt man sehr einfach über die Fahrradkette, es sitzt darauf gut eng an, so dass die Bürsten jederzeit die Kette berühren, wenn man die Kette, durch Pedalen drehen, hindurch zieht. So einfach und schnell habe ich die Fahrradkette mit keinem anderen Hilfsmittel bekommen, und ich habe schon vieles ausprobiert. Und die Bürste am anderen Ende (mit den langen Haaren) ist auch sehr praktisch zum reinigen von allen möglichen Teilen am Fahrrad.

Tuve mis dudas, el precio era un poco elevado para un simple cepillo, pero cuando limpias la cadena por primera vez, te das cuenta que vale cada euro, en combinacion con un desengrasante, me quedo una cadena casi casi nueva...

チェーンの表は確かに綺麗になるのですが、内側の汚れはほとんど取れません。

If you wanna clean grunge from your chain and cassette this tool will do it This is the second one I've bought and makes your chain set as good as new (assuming regular cleaning)
