Topeak Mini P20 multi-tool review

Topeak’s Mini P20 multi-tool includes 2mm, 3mm, 4mm, 5mm and 6mm Allen keys and an 8mm Allen key adaptor that fits on the end of the 6mm key, as well as Torx T15 and T25 keys and Phillips and flat-head screwdrivers.

The chain tool has a chain split link breaker and 15g, 14g, Mavic M7 and Shimano 4.5mm spoke keys.

Finally, there is a small knife with a part-serrated blade.

The 20 tool package comes supplied in a neoprene bag to protect it from bashes and it from bashing other items, and it also stops the chain breaker from rattling when it’s stored.

The Mini P20 is made entirely from metal and out of its carry case weighs 129g, while the case weighs 6g. The tool is 32mm wide, 19mm deep and 74mm long.

Its diminutive size and low weight mean it can be stashed almost anywhere on your person or bike, and there are no sharp edges, which reduces the chance of the tool causing injury.

The tool feels well-made without being weighty and the pivots didn’t undo over the course of the test period. It also resisted rust well, even after being left in damp packs overnight.

Allen key bit accuracy was generally good enough to torque up bolts tightly without fear of slipping, but the Torx keys were a little less honed and required careful use to not round-out bolts.

Both the Allen and Torx bits were just long enough to get into most hard-to-reach places, such as when adjusting brake lever reach, and the tool’s ability to access tight spots was helped by its slim shape.

The chain tool had enough power to split stubborn links, but it was quite bulky and required extra care to use on the bike because the tool’s body inevitably contacted the rear wheel.

The power link tool wasn’t especially intuitive to use compared to Blackburn's Tradesman Mini Tool, which I also had on test, and the chain needed to be manipulated to get it to seat correctly in the tool.

This got my hands pretty dirty when removing a chain trail-side. It did work, though, and was a useful addition given the tool’s overall compact form.

Despite the notable omission of a 2.5mm Allen key, the tool is fairly comprehensive and is aimed at getting you out of bother, tightening bolts and making adjustments to certain parts of a bike.

The knife is a frequently omitted tool, so it's good to see here, and has proven very useful when needing to cut zip-ties or split tubeless tyre repair plugs in half.

Topeak Mini P20 multi-tool bottom line

A top-spec tool with plenty of scope.

Allen key and Torx sharpness weren’t great, and the power link tool wasn’t as easy to use as other versions, but generally the Mini P20 is a good performer and light enough to be stashed almost anywhere.
