Product Description

Park Tool chain cleaner scrubbing a road bike chain

Park Tool CM-5.3 Cyclone Bicycle Chain Scrubber

The Park Tool CM-5.3 Cyclone Chain Scrubber cleans bicycle chains quickly, easily, and effectively — without the hassle and mess of removing the chain from the bike. The CM-5.3 uses an extra-large solvent reservoir and a series of rotating brushes to get chains sparkling clean. A magnet at the bottom of the Cyclone’s solvent reservoir draws particles scrubbed from the chain, effectively keeping them from being redistributed onto the chain during cleaning. The durable sponge material draws solvent from the chain as it exits the Cyclone, reducing drips and mess. The brushes and sponge of the CM-5.3 are replaceable (part # RBS-5).

Did not get all the grease off of my bike chain, even when I got out the heavy duty chain cleaner. Also was a bit clumsy in it's use, however did the work it needed to do (mostly).

My chain has never been cleaner! Love how thorough this cleaner is. Just be careful with the latches and let it sit and dry after each use, and this will last for years with semi regular usage. It's worth it to get the legit Park Tool cleaner.

I've been using the Park Cyclone for decades. They WORK and last forever. Ask any bike shop mechanic, and they will tell you that keeping your drive train clean is the best and easiest thing you can do to maintain your bike. I've had friends come to me with disgustingly grimy chains (don't be that guy), I fill my Park Cyclone with undiluted Simple Green, run their chains through my Park Cyclone (counting 50 full crank rotations), rinse with water, dry with a clean cloth, lube, and chain look like it just came out of the box.

The CM-5.3 Cyclone Chain Scrubber is hands down the best chain cleaning tool I've ever used! As someone who takes bike maintenance seriously, I've tried a variety of products, but none have come close to the efficiency and effectiveness of this one.The design of the CM-5.3 is incredibly user-friendly, making the whole process quick and mess-free. The internal rotating brushes really get into every nook and cranny of the chain, lifting off dirt, grime, and old lubricant with ease. I was amazed at how clean my chain looked after just one use—it was practically sparkling!What really impressed me was how thorough the cleaning was. The Cyclone system ensures that the chain is scrubbed from all angles, which means no more missed spots or half-cleaned links. It's also sturdy and well-built, so I expect it to last a long time, even with regular use.If you care about keeping your bike in top shape, the CM-5.3 is a must-have tool. It makes chain cleaning so much easier and more effective, saving you time and extending the life of your drivetrain. Highly recommended!

Very well made. The body, brushes, and clips all feel really solid. It has a sponge where the chain exits so it doesn't make nearly as much mess as the other ones I've used. I like that you can put the solvent in with it closed. The chain did not beat up the plastic at the entrance and exit. I checked the chain afterward and it came out very clean. It seems to have gotten most of the grit out from between the links. The brushes do not fall out when you take it apart. I resisted buying this one for many years because it was so expensive. All the parts are replaceable. IDK if it's "worth" the money, but it's more than twice as good as the ones that cost half as much.

I have been using these chain cleaners for 20+ years. I have to buy them on occasion because I drop and break them, lose parts, or move and then can't find 'em. Regardless, these chain cleaners do a fantastic job of getting off all the road grit and whatever sticks to the chain. I know I could probably get my chain cleaner if I took the chain off and soaked it...but...I'm just a guy who likes to ride his bike 20+ miles a day for exercise and fitness. It is my belief that the easier it is to make something happen, the more likely it will happen. In this case, putting my bike on the stand and using this tool to clean the chain is about as easy as it gets and the results are every bit as good as I need. Because it is easy, I do it much more frequently than I would if I had to unlink my chain, soak it, scrub it, reinstall it and relink it. Just not going to do that...and I like a clean chain which reduces the wear. That said, be prepared to spill a little degreaser (or whatever you clean your chain with) and make a bit of a mess...but it is contained in the area just below the run of the chain and you can just put down an old rag to catch the drips. When done, it cleans up nicely itself with just a bit of a rinse in the sink. In all, an excellent product that I will continue to use for years to come.

I read the other reviews and thought to myself, "yeah, I'm sure it does the job reasonably well, but how much better can it be than just doing it manually?" The answer is A LOT. This little device works wonders and does it quickly and cleanly. I wasn't ever big on cleaning my bike chain because it is so dirty and messy, but this contraption makes it all a lot faster, easier and does a better job. I didn't use their biodegradable solution (for $10) and instead used what degreasing agents I had on hand to use in the scrubber - in my case "That Purple Stuff" with a few drops of Dawn blue dishwashing liquid). Man, I cranked the chain through this solution in the scrubber a few times and the chain came out sparkling clean. It would be helpful to have a something to hold my bike upright while I backpedaled the chain through the chain scrubber, but I made due without (although my chain did come off a few times in the process). Wear disposable gloves if you have them, as your hands will get covered in grime as you do this, but overall a pretty easy process that I might do more than once every 10 years from here on out :-).
