Muc-Off Iridescent Tubeless Presta Valves, 44mm - Premium No Leak Bicycle Valves With Integrated Valve Core Removal Tool

Really good quality anodised aluminium valves, worked first attempt, different internal valve seals very useful and not included in most other kits of this type, the originally fitted seals would not have worked on my fat bike wheels but the chunky one was perfect, also like the rubber o ring seal under neath the threaded valve fixing ring, sealed much easier than the valves on my trail bike tyres which have plumbers tape around the underneath of them (top tip if youre going tubeless). Nice colours as well as a built in valve remover in the spare valve cap (so you have three)to allow faster air uptake by the tyre. Will definitely buy more from this small family run business when I convert my daughter's bike to tubeless.

Great tubeless valves that don’t clog up with sealant, like the fact that the valve cores are removable, making it easy to top up the sealant.

Had a look around for valve to convert wheels for a new bike. Most looked rubbish but these are quality. They feel quality and look quality. Very easy to install as it has a 4mm allen key slot on the inside part. Also comes with a load of seals so should fit pretty much every rim. Do yourself a favour and get some.

I use these on all my bikes would highly recommend

Thay came with 3 different rubber grommets for most wheel types, and fitting them was very easy. I put the tubeless solution in after fitting the tyre I found that to be a lot easier for me and less messy.

I tried the Milkit ones thinking they would hold air without valve core. While that is true I couldn't get it to seal properly because it was hard to get the inside rubber and the outside screw/rubber ring to attach properly (I think this is the case for other tubeless valves too). Also when I pressed the valve core in to pump, sometimes it doesn't come back out as it's trapped with the rubber valve inside.These valves from Muc-off differs from Milkit and others that it has all these features in one product:1) cuboidal or conical rubber adapters for flat or concaved rim interior profile, respectively2) hex key hole on the inside to securely fix the valve with the outside screw (very useful!)3) the outside screw has the rubber ring concealed inside by having a groove for it (genius!) unlike others where the rubber ring just gets squished out leading to a tiny leakage of air and not holding higher pressure overnight.These held pressure fine at 80psi for 30mm urban/road tyres.I find deflating, injecting sealant with the Milkit syringe, and re-inflating is quite straightforward so much prefer these valves than others.

Provide easy inflation and access for tubeless sealant

Going tubeless? These are slightly more expensive than others but worth it, everything you need and extras are supplied, including a valve cap that is a valve removal tool so 1 thing less to carry and quick to change, really good fit, I've only had a few rides tubeless but no issues so far, I recommend paying the extra for these

Buen color, buena calidad.

Fue un regalo para mi hijo, me comento que le sirvieron, cumplen su funcion, de buena calidad, quedo agusto

I have these on all of my tubeless wheels. They work well, are easy to install and they look pretty awesome too.

These work great and seat nicely on the rim.

Silly expensive for what they are but what isnt these days. Work as well as my cheapie ones but look better
