Tubeless w/ compressor - what do I need?

I have access to a compressor at work as well as the attachment to pump up car tires, and I own a Schrader to Presta adapter.  Do I just put the adapter on the valve and pump up with the compressor to seat the bead?  I tried yesterday with my floor pump but I couldn't pump fast enough for the bead to seat.

I'm using Specialized 2Bliss tires with Roval rims that came stock on my Stumpy. I also used Gorilla Tape for the rim tape and want to make sure I can get the bead to seat well before I put sealant in it, sort of like in this video: (You need to Login or Register to view media files and links)

My tool for car tires did not work well with the adapter and tire.  If your Valve has a removable valve core, just take that out use the blower nozzle and just blow air in.  Then cover with your thumb and screw it back in.  That worked really well.

+1, the adapter will not push the little dicky thing in the air chuck to let the air out.  A air nozzle with the valve core out will work.

I had to put the sealant in for the bead to catch..

I am a big fan of using simple green vs soap suds.

I'll see if I can take it to work tomorrow and blow it up without sealant just to get the bead to hook.  The valve core comes out super easy with the valves the bike came with.  (Oddly enough it came with the tubeless-ready valve stems, but not tubeless-ready rim tape!)

If its not sealing just push around the tire and try to get it to fill the rim. 


Good luck!

Was the rimstrip brown? If it was, that's. what you use to make it tubeless.

It was red, and one shop already told me it wasn't for tubeless. Looked like a pretty standard non-adhesive strip after I pulled it off.

I used Gorilla tape and doubled up on the layers. Using a compressor with the core out of the valve stem works great but you still have to wrastle the tire around on the rim to get it to seat. Soapy water ln the bead helps. Work the tire bead up onto the rim bead with your hands first. Be careful pressing the compressor nozzle directly onto the valve stem with the core taken out. If its thin metal you can bend it and your valve stem core wont screw in properly and you'll slowly leak down. Or it will rocket outta there and youll blow out.

You may have already tried this, but it helps to take the tire off the rim and inflate a tube in it with a lot of air. This blows out the sidewalls beyond normal. Leave that in the sun a while so that the sidewalls sort of set in that position. Then when you put it on the rim the sidewalls are sprung out toward the rim and they're easier to inflate. It also helps to inflate the tire ON the rim with a tube and let it set a while to push the bead into place. Then try to just break the bead down on one side of the rim to get the tube out. If you can do that without breaking off the bead on the other side, that's 50% that you don't have to worry about. I've never had any issues with Specialized 2 Bliss tires inflating. In fact, except for an S Works 2 Bliss (which has thinner, flimsier sidewalls than the Control series), I've been able to inflate them on tubeless rims with my floor pump. The S Works was more of a challenge and did require the compressor.

Had an insane week at work and never got a chance to try it on the compressor.  Hopefully next week I'll be giving it a shot.  I still need to buy some latex anyways so I might just take it to CBC and have them help me out.
