Candice keeps these hex wrenches handy on her work stand. It’s the nicest set we’ve used, with color coated tool dip to make grabbing the right size quicker. If I had to only own one set of allen wrenches, this would be it. They’re not as fast as a P handle style wrench, but they can do almost any job on a bike that needs doing with a hex head.
Made in Germany by Wera, not outsourced to some random smoky foundry. No tools last forever unless you don’t use them, but I used to go thru a set of Hex Keys every year, and 3 years in, the Wera’s have no signs of wear. That’s a good investment, methinks.
Sizes 10mm, 8mm, 6mm, 5mm, 4mm, 3mm, 2.5mm, 2mm, 1.5mm
