Makes cleaning my bike so much easier and effective.Good brushes for cleaning bicyclesAll these brushes work to clean your bike, I use the black brush all the time that one seems to be softer and flexible enough to get around the drivetrain area easier!!Excellent product, help me to mantein my bike very clean, even in the most difficult places.They're good but nothing special. A toilet brush would probably work just as well but these look better with my tools with the Park Tool logo and all. They're charging a little more just because of the brand name but im not hatin and maybe it's superficial of me but I like my tool rack to look cool and uniform. Peace!Work well and as advertised. A little overpriced in my opinion.Park Tool is the best tools and cleaning products for the job. I have tried to save money before by going with other brands, but it is never worth it. If you care about your bike, use Park Tool equipment. It’s worth the price.My first thought when I saw this product was "who the hell would buy Park cleaning brushes?" Yes, I agree that Park tools are generally very high quality and worth the money but...brushes? Who cares? So then I started searching for generic cleaning brushes from the auto or home industry and was surprised that a) there aren't a lot out there, b) none are customized to bikes like these, and c) they are all about the same price as the Park brushes.So I bought them and, as you'd expect, they're fantastic. Makes cleaning my mountain bikes easier, faster, and more effective.These brushes have everything I need to clean a full suspension MTB after a day on the mountain. The big blue brush is nice and soft for cleaning the frame, the black brush gets into all the awkward corners and dislodges that mud you just can't reach otherwise, the chain cleaning brush is very stiff and the other end of it is great for dislodging the sticky crud from the sprockets and the wierd looking blue and grey one seems great for cleaning wheels. If you need to clean a mountain bike these are what you need. They cost more than I wanted to pay but they were well worth the extra pennies.As a general rule when it comes to tools for my bikes, I buy cheap and then if it breaks I buy Park Tool. What a mistake in this case.These brushes perform exactly the same as the pack I got for £4 from a local shop, they deposit bristles everywhere and have scratched up some of the paint with the exposed wire cores. Even the brand moulding on the handles is cheap and barely legible.This product is either cashing in on the brands reputation to sell cheap crap for £27, or an imitation.Simple and easy, nothing to excited about. They work but they are a bit too soft in wire hardness and bristles, so easily bend and get flattened. The biggest one is good for washing and dusting off. As value for money, I think for what they are, their price is on the high end.Really poor product. Already unusable after cleaning only 2 bikes. Waste of moneyNice quality set. Would be nice to have more of a description for each brush use for the total beginner.
