Topeak Mini 9 Multi Tool

The Topeak Mini 9 multi tool measures a diminutive 6.6x3.1x2cm, weighs a middling 94g and has nine functions. For such a small tool, it's surprisingly pleasant to use for quick tweaks when you're out and about. However, its size/tool selection means it's best suited to those who keep their machines minimalist, or like to cultivate their own custom tool kits.

The body is made from neatly machined CNC aluminium, while the tool bits are hardened chrome plated steel. Its 2, 2.5, 3, 4, 5, 6 and 8mm Allen keys cater for most fasteners, from cantilever/dual-pivot brake and cleat tension screws to bottle mounts, seatpost binder bolts, Ahead/stems, pedals and, of course, those old school square taper cranks. Then there's the T25 Torx and Phillips drivers for tweaking disc callipers, derailleur limit screws and lighting/accessory brackets.

Despite its size, there's a reasonable amount of torque, making short work of simple adjustments – I've even coaxed some badly weathered SPD cleat fasteners and quill stem bolts free with modest effort and without recourse to penetrant sprays.

Care is needed to avoid losing the 8mm cap – say, tightening rogue square taper crank bolts or pedals. Spares can be purchased (or salvaged from those in the scrap/bodge box). It is surprisingly efficient compared with the stubby type and will spare your blushes miles from civilisation.

The sleek profile compensates for straight rather than L-shaped tools in tighter spaces – adding/tightening a second cage on the seat tube, tri-bar mounting bolts and such like. However, there's no chance of sneaking it between wedge packs, or between tyre and mono-stay mounts when giving saddle cradles and mudguards a quick nudge.

Aside from being very accurate, electroplating seems reassuringly hardy. Deliberately leaving the Mini 9 in its wet neoprene pouch for several days following some very soggy rides, and the satin finish remains blemish-free.

Ultimately, it comes down to the old horses for courses gambit. Tossed in with spare tube(s), tyre levers, CO2 inflator, cartridge and 15mm ring spanner, it's perfect for my summer road and TT-inspired fixers. Add a chain tool and it's fit for longer outings on the winter/training bike.

That said, there are some cons, and much of this boils down to price in an ultra-competitive market. If you regard multi tools strictly as contingency options, there are shop-branded models offering superior spec for around £8, and 14-function types making better transition to gravel and mountain bike needs – another consideration if you port them between bikes. (Note: there is a Topeak Mini 9 MT – for mountain bikes, with a different selection of tools.)

Verdict

Surprisingly pleasant to use mini multi-tool for quick tweaks and emergency repairs
