The 45 mm valves measure 45 mm from end to end (not including the presta core) and also from where they contact the rim at the base of the valve to the end of the presta core. They weight 6 grams each, including the presta core and cap, 5 grams without the cap. Comes with 1 small plastic core remover tool which works just fine and is great to carry along on your rides.The base is unique in that it has multiple holes around the perimeter that might help prevent sealant from entering and plugging the valve stem and core. The seal seems to be a good quality rubber and the anodized aluminum stem itself is nicely machined. The inner and outer threads are smooth so the core and nut thread on easily. There is a shaped washer that should fit the contour of most rims. I think the o-ring is to help keep the nut locked onto the valve stem.The presta cores are basic quality. I prefer the ones that use the white plastic seals rather than the black rubber. In my experience the plastic seals collect less dried sealant than the black rubber over time. For the price, it would be nice if 2 extra cores were also included. The valve caps are also machined and anodized aluminum but I don't ever see the need to use them in the first place. I'd rather have spare valve cores.

These tubeless valve stems have given me zero issues. Easy to install and no leakage at all. They are available to fit just about any rim you might have. I'm very pleased with mine.

Generally I have been very impressed by the cost:quality ratio of RideNow gear, so sticking with them for the swap from tubed to tubeless felt natural. Their 85mm stem TPU tubes fit my wheels perfectly so went with the same length for these. I have 60mm front and 68mm rear rims.Unfortunately the 85mm length includes the internal gasket and air exit portion, so the usable/functional length is closer to 75mm, whereas with their TPU tubes you get a true 85mm length that gets you all the way to the face of the tube. Additionally, the stem is not threaded as far up as their TPU tubes (about 6mm unthreaded to the TPU's 2.5mm unthreaded), so you lose some functional length on that side as well.Otherwise the finish and quality feel fine, but until they come out with longer stems I can't comment on the seal or performance.

The end is not threaded and most pumps will not grip the end of the valve, and the inside bore is smaller than most sealant injector tubes

So far so good. Install was easy enough and they seem well made. Been meaning to convert to tubeless for a while, and an annoying trip through goathead country and a hot sweaty tube replacement finally pushed me over the edge.Time will tell if they develop any problems, but none so far!

Really nice tubeless stems. Fits and seals well. Nicely machined. These are probably my go to now, they are nicer than others I purchased in the past.

If you ride off-road like I do then replacing stems is a normal routine (along with new sealant, etc.), so finding a price conscience kit that offers different options is a nice find. I've been very pleased and definitely recommend the Bibike's.

Nicely made aluminium stem. Fit a basic aluminum DT Swiss MTB rim without leaks. Glad to have another core removal tool to stick in the seat pouch tool kit.
