“A set of allen keys halfords professional range are a good quality / cost compromise. Cheap allens are a false economy.”
Oh yes. Cheap allen keys = stripped bolt heads, first time that happens on a tiny wee bolt in an expensive part you’ll wish you paid £10 more for a better set.
It depends what you want really. I bought the smaller Lifeline kit, it’s very good, not too much filler (most bike toolkits come with loads of utter crap so they can say “40 piece tool kit” but actually what you want is the 10 bike-specific tools not the magnetic parts bowl and the wobbly adjustable wrench. Not such good value as it was… But other than lacking a HT2 BB tool it’s enough to strip and build bikes into their component atoms and all of the tools are of decent quality. The cable cutters are surprisingly good.
The Icetoolz one is OK too.
Commonly people will recommend you to buy tools as you need them, but that can work out a lot more expensive, if you buy well a £40 kit can give you a lot more than 4 £10 tools will. Not to mention that when you suddenly discover you need a 14mm cone spanner the night before your holidays, having a full kit is nice!
Check out Superstar for tools, don’t assume they’re the best prices mind but quite a lot of the stuff they sell retails under different brands for a fair bit more. other stuff looks like tat though.
