Review: Road.cc - Peaty's x Chris King MK2 Tubeless Valves

Road.cc has tested the Peaty's x Chris King MK2 Tubeless Valves. Here is what they thought.

The Peatys x Chris King MK2 Tubeless Valves are a high-quality way of jazzing up your wheels. The materials are excellent, the design is well thought out and compatible with rim liners, and they're easy to install or remove. They even have valve core removers and spoke keys built into the valve caps. They are pricey but look it too... if you've got fancy wheels, surely they deserve a set?

These valves, like the original version, are a high-quality affair machined from 7075 aluminium. That's some strong stuff, and Peaty's is clearly confident – it offers free replacements if you manage to bend or break one. They come in 42mm, 60mm or 80mm (tested) lengths and a vast array of anodising options – okay, 12 – to perfectly colour-match with other Chris King components.

If you're after even more bling, there's an accessory kit(link is external) with lock rings and dust caps for £5.99, so you can mix and match colours.

These 80mm ones are for wheel rims deeper than 50mm, and I've been testing them on both 50mm and 60mm-deep wheels. It's worth noting the stated length is actually the coloured bit, and 6 or 7mm will remain in the rim bed. Consequently, on anything deeper than 60mm, you might struggle if you use a push-on rather than screw-on pump.

You may have noticed that the dust caps differ from each other slightly. This is because one doubles as a valve core remover (as seen on the the very similar Muc-Off Tubless valves), while the other doubles a spoke key. It's 3.4mm key but, although that's a common size, it's still worth checking it fits before you need it; Shimano and Campagnolo wheels usually use larger nipples, for instance, which will make this feature redundant.

These are excellent. They use high quality materials, are machined and anodized to a high standard, and they look the mutt's nuts. Are they really going to transform your life compared to a set that costs a tenner? Probably not. But sometimes you just want to treat your bike, and yourself – and the adoring crowd that really should form around your bike – to something special, and these MK2 valves are brilliant for that.
