I have a set of DT M1800 29er wheels that I am experimenting different tubeless setups on and wanted to run it by those of you with tubeless setup.  Last year, I went with the ghetto tubeless setup of a couple passes of Gorilla Tape, re-purposed presta valves and Stan's sealant using non-Tubeless Nevegals.  I had to do two full wraps of GT around the rim to get the bead to seat, but the setup lasted all summer and fall before the presta in the rear started to degrade and pull through the valve stem opening of the rim.  I then picked up some Specialized Tubeless Valve stems and that fixed the problem until the GT started to leak a little bit of air.

Since I had to re-do setup, I decided to use Stan's tape this time with the Tubeless valve stems and the tire seated up the first time but I'm a little concerned with blowing the tire off the rim since there is less "buildup" of tape to securely hold the bead against the bead seat.  I didn't want to mess with tape again, so I simply used the stock vinyl DT rim strip over the Stan's tape.  My assumption is this would help fill in the voids better and is really tight on the rim, plus I think it's a little lighter than another round of GT.  Anybody ever done this?

Why ghetto when you can do it the way DT intended.....

It's not like I don't already know that the DT kit exists.  But I don't want to spend $112 on a kit.  That's the whole point of this thread.  If you have forgotten, I will refer you to the title of this post.

Sometimes I forget why I stopped posting on this forum....however, you have reminded me.

I think the 1800 is tubeless compatible, so you should be fine

Technically speaking, just about any rim could be made tubeless compatible with today's kits, but DT did not make the M1800's tubeless until 2012.  I'm running 2011 model hoops, which are your standard tubed variety.

The question is has anyone put a standard rim strip over tubeless tape for the sole purpose of building up the sidewall space?

Yes.  Anything that builds up the inside of the rim is good, but I would look for something that doesn't move.  Back in 2001 or so, I would use the wide Velox tape to build up, and then use wide electrical tape because it would provide the air seal.  I would, like you, use presta valves cribbed from old tubes.  Worked like a charm on standard Mavic rims then.  Of course, results may vary.

I have used cut up BMX tubes as rim strips. I use about 2 of those, the another strip that has the presta valve in it (a cheap Stan's rim strip). Then some Stan's sealant and presto it's done. I used this for years on a ~2000 mavic crossland wheelset (helium type hubs) and it worked perfectly to ride and race.
