Get That New Chain Feeling.

Road racers have a saying about a feeling like they're riding without a chain when the legs are good, meaning they don't notice the resistance in their drivetrain. Of course, most road racers keep their bikes meticulously clean but we'd love to have this feeling on every road or mountain ride. One way to ensure you aren't losing precious watts to a dirty, sluggish chain is by keeping it clean. Invest in the CM-25 Professional Chain Scrubber from Park Tool and prepare to have a sparkling clean and efficient chain. This cleaner features a tough cast aluminum case and handle and it's way more durable than plastic units. The brush and sponge cartridge continuously cleans chains and is easy to replace when needed so that the CM-25 provides years of use. The rotating brushes hit all four sides of the chain for fast cleaning. So if you've just gotten back from a messy ride or you are looking to spruce up your bike for a race day boost, use the CM-25 and CB-4 Chainbrite and enjoy a smooth ride.

  • Scrub that dirty chain with a shop quality cleaner
  • Aluminum construction is super durable
  • Replaceable brush and sponge cartridges extend life

Great Chain Cleaner

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

I have had probably 6 of the plastic chain cleaners.....decided to buy the Park Tools metal one.....used it for the first time yesterday and it was a joy to use compared to the plastic machine. My chain has never been so clean! And cleanup with the new cleaner is a lot easier, and having read the instructions where you can use water with a little Dawn in it for the second scrubbing makes cleaning the scrubber a snap.
Buy it, read the instructions and you'll find the whole process a lot easier and more enjoyable (if cleaning a chain could ever be enjoyable!)
