About this item

  • With design, sustainability & quality running right to the core, there’s only one company we could work with on our valve colors - Chris King! With our valves for life guarantee and their stunning colors, your bike is in for a real treat for years to come
  • Comes with an integrated valve core remover cap and spoke key cap (for standard 3.4mm spoke nipples). This makes tightening loose spokes and topping up with sealant a breeze, either in the workshop or out on the trails
  • X-cut base is designed to work with all tire inserts; channels cut into the base of the valve allow air and sealant to pass through when inserts are pushed against them
  • Fitting couldn’t be easier. integrated o-rings prevent the lock rings from scratching your precious rims and large soft rubber bases easily create an airtight seal
  • Made from premium lightweight, high strength 7075 aluminum, Peaty’s MK2 Tubeless Valves fit most tubeless setups from MTB to road and cyclocross, including carbon, enduro and DH rims

Better than Cushcore’s valves

Better than Cushcore’s valves
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.

Before I got these valves, I had a lot of trouble with my tubeless setup: inconsistent seals, difficulty getting extra sealant in to the tire, etc. Those problems went away with these valves, plus the tools on the caps are really convenient.
