Brushy brush!

  • Familiarity: I've used it several times

Perfect for all those hard to reach spots. CLEAN YO BIKE! makes cleaning your bike sooooo much easier and a lot less frustrating.

The gear brush

    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.

      Perfect for cleaning between cogs!

      • Familiarity: I've put it through the wringer

      This brush is ideal for cleaning your cassette. It's inexpensive, durable, and works very well.

      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.

        For Anyone that Owns a Bike

        • Familiarity: I've used it several times

        Do you own a bike? Yes? Get this. Clean your stuff and it will last longer. Not sure how to clean it? That's okay, check out Park Tool's website for plenty of at home maintenance tips.

        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!

        Great for tough to reach spots

        • Familiarity: I've put it through the wringer

        Excellent and pulling out the grime in between cogs on your cassette or if you run mulitple chain rings up front.

        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

          • Familiarity: I've used it several times

          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.

          Nice

          • Familiarity: I've used it several times

          Arrived super fast. Thanks BC! This tool is exactly what I need to clean my bike! It's great so far, no issues.

          Perfect

          • Familiarity: I've used it several times

          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.

          Greasy Grimy Gopher Guts

            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.

            Useful

            • Familiarity: I've used it once or twice and have initial impressions

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

            Perfect for regular cleaning/maintenance

            • Familiarity: I've used it several times

            The title says it all. I can't get too poetic about a cleaning brush.

            Get that cassette CLEAN CLEAN CLEAN

            • Familiarity: I've used it several times

            The bristles are just the right length and stiffness to get the job done. Very well built. Can't see this breaking anytime soon
