Muc Off1053 Green Tubeless Presta Valves, 44mm - Premium No Leak Bicycle Valves With Integrated Valve Core Removal Tool

Extremely good quality valves with options of different rubber seals..it even comes with an extra valve cap that has a built in valve core remover

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.

I went for the 60mm ones to be safe, bit on the long side for my rims but if for whatever reason I got different rims I could probably reuse them.I converted Mavic 319 disc rims to tubeless with gorilla tape and Maxxis Minion DHF front and DHR rear, seated them for 30 mins with a tube and they went up quite easily with compressor. Bought big bottle of Muc Off sealant to add and they've not lost any air or sealant.This is the first time I tried tubeless and was sceptical about the tyres losing pressure. Running both at around 30psi the tyres do feel a bit too flexy for me below this, but they feel really nice, especially over tiny textured bumps like cobblestone and textured concrete.Definitely recommend to anyone thinking about converting to tubeless, there are cheaper valves around but as these look decent with a good amount of colours, have various rubber seals to fit all rim types, and have a core remover that is also a valve cap these are good value as you will probably only need to buy them once.

The tape you use makes a huge differences, but overall these are decent. I did find the rubber on the conical plugs to be a bit too soft and it meant that when trying to get the wheel to go tubeless I had to swap to the oddly shaped rubber pieces to keep the valve from expanding the hole in the tape and creating a leak. I like to tighten the valves quite far to prevent rotating in situ when inserting/removing valve cores and unless this wrenched right to the rim and really tight, they rotate too easily and the valve starts to loosen in position. So once they're tight, they're fine, but it has to be super tight! Otherwise, can't complain really... It's a valve, it does valve things.

Having bought much cheaper valves and had constant pressure issues I bought these and they have been perfect with no issues from the word go. The best bit for me is that you can hold the inside part of the valve with the Allen key provided meaning you can be sure you have everything tightened down the way it needs to be! I would definitely recommend these valves and I will buy again if needed 👍🏻

Decided to go tubeless and these Muc-Off seemed to be well reviewed. Watched a Muc-off how to go tubeless YouTube video and half hour later both wheels tubeless. So they were easy to install and they do exactly what they are designed to do and look great with some tidy innovation built in
