Peaty's Holeshot Fast Flow Tubeless Valves

These make filling up with Peatys gloop so much easier, along with pumping up and letting down the pressure compared to the other presta types. Was super easy to install too!

Great tubeless valves but if you have a bosch speed sensor on the back wheel getting a longer rear one would be better.

I was very interested to try these Peaty's Holeshot Fast Flow Tubeless Valves as they seemed to be a good middle ground between standard removable core valves and the coreless big bore valves now available.As these Holeshot are a single piece construction, like standard tubeless valves, fitting is simple and very familiar, just insert through your rim and secure with the lockring. With everything fastened finger tight there are no leaks at all.Once installed and the tire seated, I've never had a tire go up so fast, I would say it is even faster than a standard valve with core removed, they really are high flow.The main difference between these valves and standard ones is the core cannot be removed at all, this has a couple of consequences, firstly you cannot quickly deflate your tire hands free, you have to keep your finger on the valve core until it is flat.Also, it limits the ways you can get sealant into the tire, there is not enough clearance to insert a filling tube down inside the valve and you have to use the tube around the outside of the valve method.The supplied dust caps are very specific to these valves as they attached to the core not the valve body, this locks the valve core closed. Standard dust caps can be used but then the core isn't locked.The clever thing about the dust caps is they each have a dual purpose, this is handy and could be a ride saver out on the trail.I ordered the black ones but there is a great choice of colours to enhance the look of your wheels, however even the black ones look great when fitted with their neat and very clear logos engraved on them.Overall, a big improvement on standard valves and the only slight downside is when it comes to getting sealant into your tires.

Great news design. Love the fact they'll match my Chris King Hubs. Easy to use.

These are brilliant valves that offer a lot. They're very easy to use/fit but there's nothing to it. I was able to inject Silca v2 sealant though them no problem. They look great, seem very strong, and their fast flow design is certainly true. Whilst I've never had any issues seating my tubeless tyres, it's great to know these offer additional flow if needed. You can certainly tell their flow rate when releasing air. That's in fact one thing I ironically would point out as a negative since traditional presta valve cores offer more control here. Still, either way I'm used to using a tissue anyway as you normally get a bit of sealant being released and these are no different in that regard. They do have a great design which means that even if they snap, since they are sealed inside the rim, no air is leaked. They claim that they don't clog sealant - I'm unsure and it's too early to tell, but I'm sceptical. I'm used to lining my previous valves and valve cores with a bit of Silca Synergetic and never had any issues. But again, if this skips that step then even better. They come with a spoke tensioner although when I tried it on my DT Swiss G540 wheels, I had to force it onto the spoke, and removing it caused the paint to scratch - so I won't be making that mistake again. They could have done with making the opening larger. They also come with an e-bike lube cap allowing you to 'back pedal' but this didn't even fit onto my SRAM chainring. All that said, I'm pleased with them even though they're not really going to change the world. I was going fine with that I had before. Their lifetime warranty is a huge bonus but even still, I feel that £34.99 is much on the steep side for a pair of valves.

So far, I'm impressed. Really easy to install and neat. New tyres inflated first time without a compressor and really neat how you can pour the sealant through the valve, so no mess!

Massive upgrade on my old valves I run cush core and have always found it difficult to push sealant through the valve and would have to un seat the tire. These stems work perfectly my sealant went straight through the valve easily. They also look very nice and very practical with a spoke key on the cap and to top it off lifetime guarantee. All in all im very very happy with these.

Woah, for a seemingly small change they make a MASSIVE difference to standard presta valves. Sealant went through the valve easy enough using their 500ml bottle with the pipe thing and I run cushcores. Inflated insanely quick & beaded with only a track pump. Love the idea of the seal being inside the rim because I’ve had rock strikes before that ruined rides. Good job Peaty’s!

I bought these mostly because my old valves kept clogging with sealant and I was sick of it. These fixed that problem immediately. Popped the tyre onto the bead first try with just a floor pump, no compressor drama, no swearing.Been running them for a bit and zero clogging so far, even after a couple sealant top-ups. And if they ever do gunk up, you can actually take them apart and clean them instead of tossing them like the old Presta ones — pops open with a circlip, easy fix.They’re stupidly light (11g a pair) and feel solid, not flimsy. The little spoke key and chain lube caps are a nice touch too, didn’t expect that.Only thing — measure your rim before you order, they come in different lengths (42mm/60mm) and you want the right one for your rim depth.

Great bit of kitWell worth the price.

Typical of peatys kit, good quality and easy to install.

Had to give these new valves a try while resupplying with the rest of the sealant and cleaning products

Brilliant, takes the sealant easily and pumps up rapidly. Looks great too.

Perfect, super easy to fit, been running for about 2 months now and no issues, great quality, very impressed!

Easy to install and makes filling with sealant and seating new tyres very easy

Very very good valvesSuper fast flowBe aware that they are somewhat brittle and can snap if the inflator pump pulls it (happened to me )Having said thatPeatys offer a warranty I since found out and will replaceOne of mine snapped at the top but the tire remained fully inflated as the. Above seals at the base100% the best valves

Peatys released these and bought a pair..still to use so can’t rate them on use on installation and use

Just got these but the installation was great. Not having to deal with the presta core is awesome. Seating the tyre I was skeptical, but it was so easy. So far so good.

Was für eine Erleichterung. Das hätte es schon viel früher geben müssen. Einfach zu installieren.

After finally getting sick of my Hunt valves clogging I looked for another set of the high flow offerings.These fit the bill perfect and look well made and easily serviceable with a simple circlip holding the valve core in.

Makes seating tyres way easier and adjusting pressures less of a faff. They look sweet too, so definitely would recommend.

High quality as always, no install issues, in fact made inflation much better with my liners. Love the innovation.

Nothing to do with the product, but the packaging was a pain to deal with. A standard blister would be much better. Also, since I don't ride an e-bike I wanted two standard caps, so I had to order another set. Now I have two caps I don't want.

Great valves. The fast flow is a solid upgrade and they look sleek.
