Trust me, if you haven't already set your tires up tubeless, it's arguably the best and most cost effective mountain or gravel bike upgrade you can make. Not only will you be making most punctures a thing of the past (you can still get flats from tire cuts with tubeless setups), but you'll be saving weight, and you can run lower tire pressures which will give your tires more grip.
For a full tubeless setup, you'll need valves, tape and sealant. Valves are usually the most expensive piece of the puzzle with a set costing around $30 to $40. However, these BWSHLF branded ones (no, I've never heard of them before either) are reduced to around $12 (per 40mm pair) in this Amazon Prime Day deal – which is as low as tubeless valve prices get. Almost all the colors are reduced in price except for the black and oil-slick finished valves. Prices also vary depending on the combination of color and length you go for.
While most tubeless models at this price are pretty basic, the BWSHLF ones come in a range of 12 colors, four different lengths, and are made from aluminum alloy with top caps that have in-built valve core removal tools. I've only just bought a set so haven't tested them yet, but they look just as good and have all the features of the best tubeless tire valves for less than half the price of brands such as Peaty's, Muc-Off, or Hope.
While the valves are available elsewhere in the world, at the time of writing, the only place I've seen price reductions is in the US. At Amazon UK, the BWSHLF valves cost around £20 – depending on the size and color chosen.
