Wheels - Hed Jet 6 Black
Tires - Schwalbe new Pro one 2020 tubeless 25mm
Valves - Silca 80 mm tubeless with speedshield. The speedshield is key if you are trying to set up a pair of Hed Jets tubeless, IMO.
Sealant - Stans regular
Tape - Silca Tubeless 25mm
Tires went on without the use of any tools or levers, they were by no means easy though. I wouldn't love having to put a tube in there on the side of a road during a race, but it would be doable. The funny part was the first bead was actually harder to get on than the second bead. Well ok maybe not harder, but probably the hardest 'first bead' I have ever experienced. Setting the second bead took a minute or two just working it back and forth and making sure it was in the channel. Basically just had to muscle the last couple inches of tire bead on the rim, lever probably would have made it easier but wanted to see if I could get it done without a tool. It was nice not having to worry about pinching a tube in there. On the side of a road, if you had to insert a tube, those last couple inches would be a little more of a pain, since you have to be a little more delicate with the tube.
Anyways - got them both on, aired up with compressor, no really loud pings or pops, just kinda seated themselves. Took out the valve to add sealant and one of the beads would come undone. Tried this a couple times, letting the air out very slowly, but couldnt get both sides to stay in. Added the sealant with injector anyways, aired them back up, didnt have a drop of sealant anywhere and everything seated up nicely again. Everything seemed to hold up good overnight.
Tires measured out to 27mm, although that is probably at something close to 100 psi, which I would never run that high on these tires and rims, just kinda threw that much in there when I was setting them up.
Not that any of those is news breaking, but yes, HED jets are able to set up tubeless with the right stuff.
Oh also forgot to add that this was my first time using a heat gun on tubeless tape (i have probably set up a dozen or so wheel sets tubeless before this), what a game changer! Adding just enough heat to really seal the edges down and help with the bubbles resulted in the cleanest, least bubbly, tape job i have ever seen. go pick up the cheap 13 dollar one at Harbor Freight.
Thanks for the report. The Jet Plus and Jet Black stuff has been using a tubeless inner rim profile for some time now, but I've only used them with MTB tires (on an Ardennes Plus... same rim). Interesting to see that inflated tire size (27mm)... I haven't seen many actual inflated sizes since Schwalbe re-did their sizing (the 2020 Pro One is supposed to inflate true-to-size on a 19mm inner rim width, vs 15mm for the older stuff). I've used a bunch of older tubed 25mm tires on Hed Plus rims, and they typically inflate to 28-29mm.
Just curious - did you attempt to inflate with a floor pump, or did you go straight to the air compressor?
