These titanium skewers weigh only 50g, saving up to 68g over generic steel skewers. The ones pictured have plastic washers, which can split and fail, rendering the skewers near useless. However, now they make a version with brass washers instead of plastic ones. It is incredibly important you buy the ones with brass washers which are much more durable and will let you tighten them down more. The alloy faces have very little bite, but skewers are not through-axles, and mostly intended to apply compression force on the dropouts. If working as intended, it is the friction between the serrated steel nut on the hub and the dropouts that holds the wheel in place, not the friction of the skewer. However, these may not be strong enough for horizontal dropouts. I dislike the round profile springs that come with these and usually use the flat spring that come with the original skewers. They come in various styles and colors, and are all pretty similar. Beware unscrupulous sellers who advertise steel skewers as titanium. If the handle looks CNC, not cast or extruded, and they are advertised at around 50g, they are most likely titanium. At $10 and saving 6.8g per dollar, it represents an exceptional value, low cost upgrade. It can be found on eBay.
Price: $10 [Low Cost]

Recommended with caveats
Buy the ones with brass washers, and not recommended for horizontal dropouts.
