B'Twin 300 Bike Tool Kit



Inexpensive toolkit perfect for adjustment and occasional repairs

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.

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

The B'Twin 300 bike tool kit is designed for "adjusting your bike and carrying out minor repairs". This kit does exactly what it says on the tin and at a very good price.

A penny shy of £20 buys no less than seventeen different tool bits for fettling contemporary geared builds from fully equipped disc braked touring Lorries to featherweight carbon fancies. Those with hub or fixed transmissions will need to supplement it with some open ended 15mm wrenches though.

These all live in a neatly organised nylon pouch, keeping them central and theoretically preventing loss, although wrestling the bits in and out of their elasticated loops requires a little discipline. 8, 6, 5, 4, 3 and 2mm Allen keys tackle all but the most esoteric fasteners, while striking just the right balance between leverage and dexterity.

There's sufficient torque for tightening/loosening higher stressed crank, pedal and stem bolts. However, bare steel can dig uncomfortably into the palms. Badly weathered shoe cleat fasteners also required some chemical assistance.

Poor relations to ball ended T types perhaps, but I've found the 4, 5 and 6mm sizes surprisingly convenient in tight spaces like bottle cages, mudguard bridges and saddle clamps.

Torx drivers are becoming increasingly prevalent on other components besides disc brake rotors. B'Twin has responded with a T10, T25 and T30, which should future proof things.

Hardened steel is arguably a poor man's substitute for chrome vanadium and CNC is a different ball game. That said, a two year warrantee suggests the French brand's pretty confident they'll last, everything feels reassuringly sturdy. Machining is still very accurate across the board, so there's little risk of rounding off, or chewing fasteners.

Philips and flat screwdrivers composite handles offer plenty of purchase, even in greasy, sweaty palms, doing a fine job of taming wayward derailleurs and cantilever/V brake balance screws, prising open LED cases for battery replacements and so on.

A nicely nickel plated 'universal' spoke wrench is more fiddly than precision fit fare but tames minor wobbles and weaves fresh spokes in with minimal fuss.

Chain tools are one particular area where buying cheap usually means buying twice. This one follows the classic Rivoli pattern and boasts a surprisingly hardy painted finish.

Much to my surprise, the drive pin's threaded sections are remarkably accurate. Theres no hint of sloppiness here and it's munched through 7, 8, 9, 10 and 11 speed units with relative ease. Then again, the handle boasts a nice rubberised sleeve which would've been more welcome on the drive handles, especially when tackling stiff, neglected chains.

Personally, I'd invest in something slightly better and pop this one in the wedge pack for roadside contingencies but it seems perfectly adequate for occasional repairs and replacements.

Then we have a pair of polyamide tyre levers, which rank amongst the very best I've ever come across. Innovative and extremely efficient, they're supposedly safe on all rim types and feature a handy pip for bleeding pressure/deflating Schrader valves.

The levers' hooked edges grip spokes securely when pitted against stubborn beads. The tips are more effective than most and there's no hint of flex when applying force. These levers are available separately in packs of three for £1.99. I'm sufficiently impressed that I've invested in several sets for each of my bikes, which should tell you something.

Two are adequate for general duties, although a third was essential for the tighter tyres in my fleet: some 26x1.6 Vittorias, Schwalbe Marathon plus, some 23mm Kenda and those notoriously stubborn, bargain-basement 16 inchers that seem standard OEM issue on trailers and tagalongs.

Being picky, there are certain bits I would upgrade according to personal preference. Otherwise, everything's pleasant to use, fit for purpose and represents excellent value for money.

Tell us how the product performed overall when used for its designed purpose

Overall, this kit is extremely well thought out, does most jobs very proficiently and proves you don't need workshop quality stuff for tweaks and occasional repair. However, while accurately machined and relatively well made, the Allen keys are no-frills affairs, which can press painfully into the palms when tackling particularly stubborn/weathered fasteners.

Looks overpriced to me for what it is. Planet X do a kit for the same price with cassette lockring tool and chainwhip, BB tool etc etc and they're not the only ones.
