From a professional perspective both these items are great, the GG-1 is a little tricky to prime, but once it's done it works well and control of the grease is perfect, thread like as opposed to string like. The CM-25 is another excellent item, i wouldn't buy it for home use but for a shop it is great, i use mine between 1 and 10 times per day and it is a lot easier to work and clean than the old plastic ones which tended to clog heavily if used on a seriously soiled drivetrain. - just my tuppence worth.
Just bought one got your info too late but i will look for cap to fit the bottom. Quite easy to take the chain off and drop it in bucket of diesel oil. Interesting video keep the coming thanks
No doubt that they might do great tools. Ok. I understand that the chain has to be as clean as possible, but 90 euros for a piece of plastic ... they can not explain this, they are out of this world. : ))
Unfortunately not. Park Tools state that they manufacture all their products in Minnesota but I doubt that really goes for all things. I compared it to a Hazel and it pretty much looks and feels the same.
I have been using one for several months now and really like it. The internals (2) are each modular one unit pieces that you just pop in and out unlike the older plastic units. That makes cleaning both them and the unit that houses them very easy. The modular unit bodies are plastic not metal, which makes sense given that they are meant to be replaceable after you have worn out the pads and brushes. So far I've done about 7 or 8 chain cleanings without an issue. Based on my usage I'll probably be replacing the modular units roughly once a year. The biggest issue I have with the unit is the cost of the replacement modular internals, they run about $18 to replace a set. I think Park should try to get that price down into the $10 range, and maybe they can be had at sales prices if one is patient and plans ahead? I looked at that negative review you mentioned on JensonUSA, and all I'll say is I think he was talking out his arse. First, he said the unit opens backwards which makes it hard to use? That makes no sense as the unit has to open either forward or backwards and backwards towards you is how you want it to open, otherwise you'd be opening it into your wheel spokes. Put the unit over your chain (which is kind of necessary to actually clean the chain unless your David Blaine and can somehow thread the chain through the unit without opening it LOL) and it is very easy to use. I'm also not sure what chain he claimed would not fit through the scrubber?? To date I have cleaned an 11 speed SRAM chain, a 10 speed KMC chain, and a 10 speed Ultegra chain with no problems (pretty generic chains). It works just like the old Park plastic models.
