    27tpi knard tubeless on the rabbit hole rim

    Is anyone running the 27tpi tires tubeless with success? If so what's your setup like?

    I did mine using a split tube over nylon ribbon with tuck tape. It works fine, but the sidewalls of the knards get punctured by anything even vaguely pointy, such as sticks. I am using 4 scoops of stans which seems to be helping to seal the punctures. I will probably go to 120 tpi tires next summer.

    I'm planning on running the split tube as well. I'm surprised to hear that about the sidewalls. I have heard several people having problems with them burping though.

    Split tubes are probably the best method, but here is what I did: Got rid of the Surly rim strip and ran one layer of Gorilla tape directly on the rims. The sticky side shows thru the holes so I dusted them with talc powder to cut it down. Here later all the tackiness is gone and not much dust or anything has adhered to them. 3 scoops.

    I'm running the Knard on P35 using split tube. Been this was the whole season and no issues with burping or sidewall punctures.

    Edit: By the way, 120tpi Knard sidewalls are way thinner than 27tpi. If you're having sidewall issues, 120tpi will not work.

    Sidewall punctures are a real problem for me when I had the 120tpi tire up front. I replaced it w/a 27tpi tire and it has not been punctured yet in 3 months of riding. I run mine tubeless using split tube, Gorilla tape (1 layer) over the Surly rim strip. Tires air up w/a floor pump! 3 scoops of Stans.

    What's the purpose if the gorilla tape? I set mine up split tube with only the surly strip.

    I used the Gorilla tape in conjunction w/the liners for 2 reasons. 1) It made it so I wasn't dealing w/sticky crap facing up through the "rabbit" holes and 2) it made it much easier to air the tire up because the tire had contact with something pretty much all the way around the rim. Made it possible to air up with a floor pump.

    Oh OK. I struggled a bit getting the tires to seat using a compressor but I finally did with the help of lots of soapy water and pinning the wheel between the ground the wall and my leg at the same time.

    Good to hear. My rear 120 looks like a pin cushion. I think I have as many plugs as knobs

    I've been running split tube and the surly rim strip for about 3 weeks now with no issues. Came close to a burp on the first ride when I landed a small jump at speed going into a corner. Got a weird bbbbbbrap out of the rear tire, but it held just fine. 185# rider @ 15psi. I've since let the pressure down to about 10 front 12 rear, but that seems to be the point that things get squirrely for me.

    I have been running my 27 tpi Knards with duct tape and split tubes for a few weeks. No problems what so ever. I run the front at 9 psi and the rear at 11 or 12. I am 188 lb or so. Not fluffy beach riding either, real mountain biking.
