At road.cc 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.

Good scores are more common than bad, because fortunately good products are more common than bad.

Peaty's Max Grip Carbon Assembly Paste is a secure and easy-to-use product, and as heavy on the abrasives as you could want.

Not the most glamorous of cycling products, gripper paste is nevertheless a workshop essential anywhere carbon parts are being installed.

Seatposts and stems/handlebar interfaces are inclined to slip, and trying to prevent that by tightening the bolts a bit more can result in disaster. Furthermore, using ordinary grease to ensure parts don't get stuck together can make matters worse.

The answer to all this is carbon assembly paste, which lubricates the components enough for them to go in and out easily, yet 'bites' into the carbon enough to prevent slippage. Peaty's Max Grip is, as the name suggests, pretty well certain not to slip, thanks to a high proportion of abrasive.

Some – like Fenwick's Carbon Assembly Paste – use microbead plastics to provide the friction. Others are silica (i.e. sand) based. In Peaty's case, it's powdered volcano. That's right, it's pumice, like what you use to polish your twinkle-toes in the bath.

Armchair experts

There may be an argument that plastics are safer as they're less abrasive (and shoot less lava than volcanoes), and there's a whole internet rabbit hole you can disappear into if you've nothing better to do.

However, bear in mind that abrasives only scratch if there's movement, and the whole point of assembly paste is to eliminate movement, so it's hardly likely you will be fatally sandpapering your seatpost.

Peaty's paste has a gel-like consistency that makes it easy to apply, with less waste than some runnier compounds I've used. This is made from natural oils (petroleum-based ones are common in carbon paste), which we are assured are all non-toxic and readily biodegradable.

Note that the use of carbon paste does not mean you can tighten bolts to lower-than-recommended torques. Do them up to the manufacturer's specification. The point of the paste is that at these torques, the components will be absolutely secure. I was totally confident in the grip resulting from using the Peaty's product.

Value

The price is good too. At £9.99 for a 75g tube, it's a fiver cheaper than Muc-Off's Carbon Gripper, for instance. Meanwhile, Motorex Carbon Paste comes in bigger 100g tubs of 100g, but costs £22.99.

Oh, and the tube itself is made from recycled plastic.

Good stuff.

Verdict

Works very well, is natural and biodegradable, and it's cheaper than some brands too
