good 29er tubes?

29er slime tubes is all you need.

Bontrager tubes with the removable core, get a baby medicine syrynge from your pharmacy (usually free if you say they are for baby meds), take the core out and fill with a few ounces of Stans or Slime.

If you already have some tubes with a non-removable core..

1. snip off the very end of the core post with a wire cutter or *****.
2. unscrew and remove the nut
3. let the post drop into the tube and clear of the valve, but hold on to it inside the tube by pinching it between your fingers.
4. squirt in desired sealant
5. poke post back into valve. hold valve downward and shake it out, or tap with your cutters until the post pokes through and replace nut. you can hold the post in place with needle nose pliers. These often have a cutter so they are my tool of choice.
This only takes a few minutes and is much cheaper than Slime Tubes if your thrifty like me.

good idea chongoman. i may look into those. I am wondering if the perforance tubes i used this weekend to repair my flats were old too. i cant tell you the last time i bought them, so the splitting seams could have been an age thing too.

I have stans in my wifes tubeless 26er wheels and love it.

someday, i will pony up the $500 for the new wheels.

I second Chongoman's idea. I did that with my commuter bike with shrader tubes and no issues on canal riding with road tires.

Also, I once read that they USPS team mechanic would age tubes up to two years before using them on the team bikes. At 120 to 140 psi they didn't have seam tears on old tubes. Just my $0.02 as well.

USPS team used aged Tubulars... not tubes.

I like the continental and WTB brand tubes the best.

Ohhhhh, that makes more sense now. Thanks Lethal. :thumbsup:

I did a ghetto conversion using the split tube method and it has worked very well. I didn't want to drill my rims for schrader so what I ended up doing is buying some presta slime tubes, split it and cleaned out the slime and get up the ghetto tubeless setup. The reason I use slimed prestas is because they come with removable cores! Makes injecting Stans a breeze and you don't have to deal with clipping the nut and having it fall into the tube by accident.

Or just use Caffelatex which can be injected into any tube with or without a removable core.

Go tubeless.

Ha. Seriously, I used every excuse in the book to stick with Slime tubes, e.g. "Well I hardly ever get flats," until this fall when I went for a ride and heard a hissing sound, only to look down and see a green stream of slime spraying on my calf from the tire. I picked up a few goatheads apparently. I stopped to investigate, and by the time I came complete stop stop of my tires were completely flat and green slime everywhere. Granted, this is the worst experience I have ever had with tubes, but one time was enough for me to com up the cheddar to get some new shoes and Stan's setup. {Note: Don't get the generic strip - go on their website and order the strip made for your rim.} Now I absolutely love tubeless and I quickly converted my SS to tubeless the same month.
