Park Tool CM-5.3 Cyclone Chain Scrubber

The Park Tool CM-5.3 Cyclone Chain Scrubber is a great option for cleaning your chains. I did two chains that had never been cleaned with a scrubber before (in the past I would use an old rag with a de-greaser, soap and water). Both chains were 2 years old and were just caked with oil and road and trail debris from the PNW (our 13-month rainy season can be hard on a bike).

This chain scrubber did a good job, you should have seen the dirt (I replace the soapy water 3X's). I did wipe the chain with a rag first (de-greaser), but the scrubber made the chains shine. I didn't use the handle just cradled the scrubber and it worked. I recommend this device, I also recommend BikeTiresDirect too... :)

Pros: Cleans the chain easily, and without having to take it off the bike. Then, I can take the top part off and dip a toothbrush into it to scrub the jockey wheels and the crank, getting the whole drive train nice and clean.

Cons: Falls apart after a few months like a politician's campaign promises. Not good. The pins that hold the clips onto the unit fall out. The handle fell off, in my hand, while spinning the crank. Lovely degreaser swill all over the basement floor. Aggro-ed the wife. Not good. I think there is an incompatibility in the materials Park uses and the degreaser chemicals. Seems to attack the epoxy they use to keep this thing together. Without the handle, I can still use the unit, but with the clips gone, I can either buy this one, or lay out bigger money for the aluminum one, but if you read the reviews, that unit has its issues as well.

I use this to clean my chain after a long ride to get out all the road grit and dirt. Its part of my chain lubrication ritual and chain maintenance.

This seemed like a good idea, so I tried one. It was disappointing. For years I have simply removed my chain and cleaned it in solvent in a small pail. After buying this, that is what I will continue to do for a regular bike. There is little to taking off a chain and reinstalling it. It cleans easier and better in a pail and the pail is easier to clean up than the Cyclone. Besides, once the chain is off the bike, it's easier to clean the derailleur parts.

My wife is short and has two bikes with a small frame size. The Cyclone's length makes it nearly impossible to use on these. When you turn the crank, there was no clearance between the pedal's rearward position and where you need to hold the Cyclone.

I give it some credit because I bought this primarily to clean the chain for my recumbent trike which has about 2.5 times the chain of a standard bike and removing the chain and re-routing the chain through the various tubes and idlers is not as quick and simple as removing a traditional bike's chain. It has a benefit for a quick cleaning on the recumbent. You need a large bucket and lots of solvent for that much chain!

This makes is very easy and fast to fully clean a chain with some simple green

The only downside is that these only last a year or so before falling apart but it's still worth it and overall cost for the cleaning tool ends up being about $2-3 a month

This is a must-have product for road riders who, like me, ride in the winter amidst salt & grit on the roads. I have also used it on my old bike, mounted on a Kickr Core in the basement, whose chain needed cleaning & lubrication.

Easy to use. Just be careful when closing the clips that hold top and bottom pieces together and removing the magnet from the bottom - they are easy to misplace or lose. Works well with degreaser or Simple Green or Dawn detergent.

Meet my expectations. PC

Very useful and well made tool. Standard parktool quality

The quickest way to get the chain clean without removing it. Easy to use, we'll see how the plastic holds up over time.

Very easy to use and does a great job of cleaning the chain with minimal mess

This product is simple to use and does a great job at making your chain shine. My friends chain on a bike he bought recently was almost black. It made it shine like a new silver chain. My friend was amazed!

I'd buy again. In fact I bought another one as a gift. Love it.

The product is durable and very easy to use. What more needs to be said?!
