Stans + New Rim or Ghetto tubless part III

In this episode of Ghetto tubeless (part III), our lovable fat boy follows the directions and finds himself as frustrated as ever.

I read the compatablility matrix:

Rim Type: WTB Laser Disc Trail 29er

Stans Strip: Plus Four

Directions: This rim has an extremely large rectangle drop channel in the center of the rim. Remove existing rim strip, use two layers of my 12mm spoke tape over the spoke holes. Then apply one layer of foam weatherseal 3/8 inch wide X 3/16 inch thick in this drop channel. Then install Plus Four rim strip. (Use Frost King foam weatherseal Gray item # V443 $2.00 for a 17' roll)

Check, check, and check (substituted brown for gray weatherseal, it's all Home Depot had).

I watched the informational videos:

After multiple shake,lay flat, repeats I finally got my tires to seal. Overall the process was a complete PITA. As I shook, soaped and repeated thoughts of changing to a different tire sent chills up my spine. Is this how it would be every time? What is the advantage really? I had heard hype from so many people, about years of not having issues, did they all go through this much effort initailly? IMO, changing a tube isn't really that big of a deal. I was hoping that going tubeless would mean lower pressure, but since I routinely run less than 30 psi in my tires, I don't see Stans as being that big of an advantage there. They will lower rolling resistance, so that's good, and it's nice to know that small holes, thorns, and bits of glass won't leave me with a flat. But concerns of sidewall gashes and trying out new tires has me wondering if I didn't line the wallet of Stans & Home Depot unnecessarily. Only time will tell.

Going custom

So after many months of thinking about it, and kicking the idea around with the wife, I decided to go custom for a new 29r. This was on the fast track as I had a huge commission that was supposed to pay out in February, however things didn't go as expected and the commission isn't going to be what I had expected. Looking in the garage, and talking to my CIO (wife) I've decided to sell off the old herd. I'm selling the SIR9 and the ti Kona... and if I get what I'm looking for, I might even sell the Gunnar, but I'm really having a hard time letting go of that bike... every time I throw a leg over it, I tell myself I can't part with it. Sentimental bike for me. So anywho, if you know anyone looking for a a small SIR9 or a groovy ti Kona in 96/26 form factor let them know. I'll post more details about the custom build as I get them. I'm working with a builder, and hope to have CAD drawings early in '08.

When all else fails read the directions.....

..... or watch the informational video.

If you've been following along, you no doubt know that I recently purchased a set of King Wheels for the new ride I'm planning (Thanks Joe P for the specs bro, talking to Scott about fit etc). I also recently joined the masses and tried out Stans Notubes latex system. While it worked great on my AC's it sucked on my older wider Crossmax. I figured I'd try it out on the Kings since they're new. The first go was tough, I couldn't get the bead to seat correctly and after about 40 minutes invested decided to toss a tube in and ride. Today I decided to try again. First I installed a tube to set the bead, once set I removed the tube while leaving one bead intact. Next re-install the loose bead leaving room at the bottom to accommodate a valve core and the liquid latex goop ... what a stroke of genius... sorta. This process worked w/o a hitch, but I found that the rim bed of the WTB Laser Disc is too wide, deep and has an ugly seam. In frustration I went to the notubes site to see where I had gone wrong.

Mistake #1 use the proper tape. I used the thin straping tape rather than the more dense yellow tape or rim strips.

Mistake #2 I didn't leave a tube in for an hour or greater to force out any air bubbles from the tape. Pretty important step apparently.

With those things in mind, I'm going to head down to my LBS to see if they have any of the yellow tape, and I'm going to pick up some epoxy or silicone to help seal the seam on the rim. I hope this will be a good solution, and if it holds up as well as it has on the AC I think I'll be pleased. I wanted to slam Stans for being too hype, but they have great detailed how to's on their site, and I really have no one to blame but myself.
