I recently came across this:
http://www2s.biglobe.ne.jp/~outex/tubelesskitenglishlist.htm
I am really tempted to try this on my new shoulderless Morad 2.50x18 rear wheel (Talon KTM 500 MX disc brake hub, SS spokes)
I just weighed a 4.00x18 inner tube I had, it was almost 2 LBS!! It may be a Heavy Duty offroad tube, but still stupid heavy. And most available premium tyres are tubeless anyway these days, so not ideal for use with a tube. Losing 2 Lbs of unsprung and rotating weight seems like a good deal to me, unless there is a catch somewhere.
(I do realize that my Morad rim is missing the "bead retaining bulge" that some dedicated tubeless rims have) And the tire I am using is Avon AM26 in 120/90-18.
