For weight weenies that are more concerned with sleek looks and gram savings than saving a few seconds during a wheel swap, Halo’s Hex Skewers may fit the bill.
The axles are straight chromoly, so you’re not giving up strength like with some machined, unobtanium options, and end nuts are anodized alloy. The axles use a 5mm hex key bolt head on one end and thread into a steel “no turn” nut on the opposite end that makes tightening easy. The nut also has slots to fit a 15mm pedal wrench, too, just in case things aren’t cooperating.
Three standard versions are available: 100mm front and 130/135mm rear, plus two extra long versions for 100 and 130 hubs on bikes with thicker dropouts. Halo’s a UK brand, and US Retail is $18.99 (through BTI). Not bad for a set that weighs in at a combined 70g. They’re also presumably a bit more aero and, while not really touted as a security item like Atomic22’s bits, they’d certainly slow down a thief.
