I prefer removing the chain and giving it a thorough cleaning about every 3,000 miles, but with the newer chains (mine is a 10 spd Campy Record), there is not a master link, so it's not a good idea to remove the chain. This unit does a very nice job cleaning the chain! I am happy with it (as I am with most everything from Park Tool) and would recommend it to anyone who asked!
My old chain cleaning tool broke so I had to pitch it (don't recall the manufacturer of it) but this one by Park Tool is made much better and is easy to use. I wish it contained a larger container of chain degreasing fluid (I had three bike chains to clean) but you can't have everything.
Got this product because I was destroying shop rags and sponges everytime I washed my biks. In addition, This is a great way to keep your hands clean if you just want a quick clean of the chain if they bike isn't so dirty.
Overal the cleaner does it's job, but has following flaws compared to Finish Line
- requires more detergent because of a different design
- uses two small clips to hold the top component in place, which requires twice the number of moves to open and close, finish line only has one, and it's sturdy enough
- in general feels like it requires more time to clean a chain with it (that's very subjective personal opinion)
The device is easy to set up and use despite the unclear instructions. Example the instructions say to put the rear chainring in the smallest setting. They really mean Shift the front derailleur to the smallest ring. If you dont, expect to see the chain jump off.
It does a good job of cleaning
