The Torque Covert 7 Crank Multi Tool is a seven function multi tool filling that otherwise empty space in Hollowtech II and similar cranksets. A strong magnet holds it there, rattle free, until you need it. In the last two months, it’s won me over with its convenience and use-ability, but remember to remove when washing the bike to prevent tooling tarnishing.

Pros: Convenient and generally pleasant to use.

Cons: Pricey compared to more traditional multi tools.

Materials/Specification 3.5/5


Supposedly compatible with cranksets greater than 21mm, the body and chain tool are made from CNC machined aluminium alloy. 6061 for the body, 7075 for the chain tool, which features the Neodymium magnetic plate, ensuring it latches securely to the crank sleeve, until required.

Six of the seven functions are made of hardened, plated alloy steel should cater for the basics required for most contemporary bikes and comprise of 3,4,5 and 6mm Allen keys, T25 Torx, Phillips’ screwdriver. These also employ magnets, reducing the likelihood of loss.

These should cater for stem/preload bolts, seat post and saddle bolts, derailleur mounts, mudguard, bottle and carrier hardware, brake bolts and most eventualities. Sure, you’ll still need a T30 for some chain ring bolts and some others for specialist fasteners but covers most bases.

As you’d expect, given the design, bits stow away into designated parking spaces within the gold anodised body, until needed. Whip the desired size out, place in the articulated socket head and crack on.

Durability/Corrosion Resistance 3.25/5

Being parked inside the crank, the Covert is very easily forgotten. Several weeks of wet, greasy wintry conditions, coupled with several sudsy bucket washes, Covert still in situ, I wasn’t surprised to discover some obvious orange taint on the steel socket and tooling plating. Much like nickel plated tools left in wet wedge packs, this is easily dismissed and subsequently foiled with an oily rag once-over. 

Alternatively, whip it out weekly and give a quick blast of GT85 etc.

If its slumbering in a frame treated with Waxoyl/similar, you’ll need to be mindful of this turning liquid during the warmer months. Otherwise, the Covert will be covered in gunk. In these scenarios, a plastic sleeve place over the tool may be the answer but I’d still carry some inspection gloves and maybe a wipe, or too. Though functional, there’s a question mark over the chain components’ durability. Ours is showing some superficial wear after just a few uses.

Otherwise, the tool feels solid, even under load, say when tackling stubborn cleat bolts Obviously, these tools are designed for quick tune-ups, not workshop duties. Given the chain component is aluminium alloy, I wasn’t surprised by evidence of wear, after a few weeks. 

Performance 3.5/5

First up, I was initially a little sceptical as to how silent it would remain, especially over washboard tarmac. A combination of precision fit, and powerful magnet have ensured its’ clung-on limpet-like. That said, it’s worth checking the chain tool is wound fully home from time to time. I reinstated ours without doing so, having fitted a fresh chain to Ursula and over the course of a week’s mixed terrain riding, a subtle, intermittent tinkling kicked in. 

Mudguard stay was my first thought, but a process of elimination led me to the Covert. I discovered the chain spreader had worked loose and the main tool had to be extracted with long, needle-nose pliers upon my return. Nipped tight, silence restored and no repeats to date. Elsewhere, the articulated socket head ensures its nimble in tighter spaces. 

OK, so with the rear tyre inflated mudguard chain stay bridge bolts have called for something skinnier (I have a standalone 4mm from a flat pack furniture pack, perfect for such duties) but no issues with reaching bottle cage hardware in small frames. 

Bits are solid and precisely machined, no hint of rounding or similar nastiness with decent quality fasteners. I’ve managed to chew a couple of Allen heads, but these were bargain basement “made of cheese” stuff.  Pattern cleats being particularly vulnerable examples (and ultimately exorcised with the T25). 

I have even managed to slip an 8mm “cap” from another, dead multi tool on the Covert’s 6mm and released an old- fashioned square taper crank bolt. A standalone key, or one common to “pen-knife" models, such as Blackburn Wayside Multi Tool  or the Lifeline 18 in 1 Multi tool With CO2 inflator .

This arrangement required greater concentration to swerve slippage and potential damage but proved rescue is realistic- handy on a group ride or coming to a stranger’s aid. A long, slender standalone 5mm key will be necessary for some deeply recessed bolts-brake levers, including The Cane Creek SC5 .

As I’ve said before the articulated head, coupled with body length means the Covert 7 offers a decent amount of torque, while also giving knuckles a sporting chance. Stowed away in the crank, I’ve defaulted to it, by the roadside and while performing post wash checks and light tune-ups.

Ours has broken and rejoined 8, 9, 10 and 11 speed chains. However, it felt less solid than some, when tackling more weathered examples. 

Value 3.5/5

Though relatively unusual, some would say, expensive given the number of functions, the Covert 7 is considerably cheaper than some, with a similar specification, including All in One Multi Tool V3 Dub OK with Chain tool, which weighs in at 67.90 (euros) although we’ve seen it a good deal cheaper through some online retailers.  If you weren’t set upon filling “empty” crank space, One EDC Lite Tool is a nine-function model designed to fit in the fork steerer and comes in at £44. However, you’ll be trading the chain tool component for more Allen keys. 


The Torque Covert 7 Crank Tool covers most bases for modern bikes, is always on hand and competitively priced compared with similar designs. I’m not completely sold on the chain tool. Sure, it’s functional enough and should rescue you by the roadside but I’d use very sparingly. 

There are cheaper “pocket workshop” models catering for most eventualities, the Passport CDW Multi Tool  and Lifeline 18 in 1 Multi Tool with Co2 inflator represent superb value for money. However, these are candidates for wedge packs, not concealed within the bike.

Verdict: 3.5/5 Cleverly engineered but chain function feels less robust than some.
