Park ToolAWS10 Fold-Up Hex Wrench Set 1.5-6 mm,Blue

Had mine for over 7 years and the only thing wrong is the plastic washers between the Allen keys snapped from wear and tear (I'm a bike mechanic so it's used ALOT), easily fixed with metal washers. Got this one for a friend who loved mine as it's such good quality. Would definitely recommend as these are the best Allen keys I've ever used and compact enought to keep in your pocket. Worth every penny

When it comes to bike tools I feel you can not really go wrong with Park Tool. They are made with quality components and you really can tell the difference compared to cheaper alternatives. The last thing you want is a cheap tool rounding out bolts or making jobs harder than you need them to be.This one is in my bag at all times when riding as it has a good range of sizes for pretty much any job you may need and as it folds into itself its nice and compact.Great tool and can not recommend enough.

They are really handy for bikes and scooters but sandals my brake calliper was in a snug spot and needed a shorter hex key to access.I had to replace with the ones on the right of the photo so if you have any tight spaces these might not be what you're looking for.If you don't have any tight hex bolts then these are great quality, light, fits nicely in a backpack and affordable.

Good quality handy tool

Best bike tool kit.

Park tools are a bit more expensive, but usually worth the extra. This is true in this case, as although the frame is made of plastic, it seems really good quality and will definitely outlast my previous purchase of a similar tool from a high street store chain, which fell apart (the tool AND the store chain!).

This is in constant use when I am working on my bikes. All the necessary sizes are to hand in one tool. You can tighten the allen keys up as they will loosen up with use. For the price I cannot see any downside of getting this from Park Tools.

I first came across this being used as the weapon of choice by the technicians in a big bike shop, and was delighted to see the tool was perfectly affordable. Despite the plastic body, this thing is rock solid, and just lasts beautifully. The tension means the individual wrenches stay at the angle they're pushed to, and the plastic body appears perfectly strong enough to crank as much as necessary, while being quite lightweight.
