Peaty's X Chris King MK2 Tubeless Valves Presta - Integrated Spoke Key & Valve Core Removal Caps, Mountain Bike, Road & Gravel Bicycle Tyre, Insert Compatible, 7075 Aluminium - 42mm & 60mm

I bought them all so you don’t have to. I think the Peatys are my favorite for use with tire inserts. Like cushcore’s valves, the peatys have groves at the bottom to avoid sealing shut against the insert. Unlike the cushcore, the peatys have a much wider inner diameter which allow faster inflation to seat the tire beads, and allows the use of sealant injectors with a long tube (like KOM injector). The cushcore valve inner diameter is too narrow for KOM type sealant injector.I just wished they came in a slightly shorter size like the 35 mm Stan’s (the longer they stick out, the more exposed to impacts…)Edit: I also recently tried the new Santa Cruz Reserve Fillmore valves, great concept but unfortunately they don't work at all with Cushcores as the inserts pushes on the valve mechanism. I suppose one could hollow out the insert but meh. (also Reserve claim they are compatible (they definitely aren't) and doesn't answer support requests...)

These stems are sturdy, seal really well and work with my Cushcore's perfectly. The finish is really high quality and the black valve core is a unique feature from an aesthetic perspective. What I didn't expect is how large the barrel is for the valve stem cap. It has a nice knurled texture that makes it so satisfying to remove and replace when checking pressures. It feels like it will last forever.

My valve was getting blocked by the insert (nukeproof ARD). These don't get blocked and have 2 tools on them. Pricey, but was worth it for me. I wish they came in a shorter option though. They could lose about 7mm and work fine for most mtb rims.

This works well with my rather tight-fitting Silca frame pump that has a hard rubber chuck. Other valves (eg MucOff) do not.

There tubless valves and they work not much els to say they got the bling bling that help put them past the 10$ amazon ones the tool is kinda corny as a cap kinda clunky

Muc off failed twice in very little time so I got these. Look nice, have tools in the caps, and have great air flow.

Not a perfect fit in my 19mm side rims but it does work once sealed up with the juice. Look Bomb

Extremely high quality prestas are one of my favorite parts of these valves. So far they are flowing great with orange seal. Ive already gotten plenty of compliments and questions on the caps which have already been used on spoke nipples and for core removal.

I'm happy with the tubeless valves. They're easy to fit and install with great colour options. The inside end of the valve is slotted so that the valve can be tightened against the lock nut. This is a nice touch ensuring a snug airtight fit. Each valve comes with a tool built into the valve cap. One is a valve tool and the other a spoke key. The only downside is the high price. Overall I'm pleased with the purchase and would recommend.

Very good indeed. Easy to mount etc. Particularly like the extra air holes or a-holes on the circumference of the valve base. These a-holes allow lots of air to enter the tyre when inflating and they reduce the problem of a clogged a-hole due to sealant. Excellent design.

i really like these, a bit expensive, but install easily and the shape of the seal seems to work better than the Muc-Off ones I also have. Sealed first time, no issues. Tools in the caps are an added bonus.

These are expensive but I decided to get them based on reviews and reputation. Hopefully they will not disappoint and will last

Great and easy to use. High quality and last well. Colour of the orange version is a bit more matt than the pictures suggest.
