Morgan Blue Cassette Brush



Effective at cleaning cassettes, but costly for a brush
Gets right between cogs
Easy to hold

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Morgan Blue Cassette Brush is an effective tool for getting the muck out of cassettes. Its long bristles can reach down into the depths between even the biggest cogs. It's rather expensive, though, for what is effectively just a tough plastic brush.

In the past I've tried the classic four-way claw brushes for cleaning cassettes, but find the long bristles a little too weak for getting in and shifting gummy dirt.

The advantage of Morgan Blue's cassette-specific brush is that it's really beefy. The surface area of the bristles is nice and big, and the bristles are not only quite stiff, they're long too.

What this means is that when you use the brush to clean your cassette – along with your chain cleaner of choice – it really gets in to all the gaps and agitates the oily dirt. And because the bristles are stiff, you don't have to worry about the sharp teeth damaging it.

The only thing I would say is that ideally you need to compliment the Morgan Blue Cassette Brush with a smaller brush (a toothbrush, for instance) to get around the back of the cassette, for more detailed cleaning.


At £8.95 this is a little on the pricey side for what is really just a common-or-garden stiff bristle brush. I've seen good quality brushes that look almost identical for about £5 online.

You could even use a regular scrubbing brush which you can pick up for about a pound from somewhere like Wilko. On the other hand, single brushes from big brands such as Muc-Off or Park Tool tend to be at least £6 as well, so it's not that extreme for a cycling-specific product.


The Morgan Blue Cassette Brush is very useful thing to have in your bicycle cleaning inventory, as it makes easy work of cleaning cassettes, but it's hard not to feel it's pretty overpriced.

The price.

How does the price compare to that of similar products in the market, including ones recently tested on

We've not tested a specific cassette-cleaning brush on (expect for those that came in a kit of brushes - the Muc-Off 5x Premium Brush Kit, for example). You can pick up a very similar brush for about £5 or less, or as little as £1 for a regular scrubbing brush from Wilko, or the like.

Use this box to explain your overall score

This is effective and should last a long time – the only downer is the price, which is very high for something that closely resembles a dishwashing brush. However, single brushes from other big brands are generally £6 or more as well, so it's reasonable within the market. Overall it's still above average.
