    Anyone ran the stock Crossmarks on the X3 tubeless on the S-XC rims? The are good tires in my area, mostly hard pack so I'll probably stick with them until they wear out.

    The Crossmark 2.1 is a good fast light rolling tire but that sidewall is so flimsy. I couldn't make it work on the stock wheels from my Anthem X1, but that doesn't mean someone else can't. Maybe I need to try again. The WTB 2.4 MutanoRaptors I had went tubeless much easier.

    I used the ghetto/gorilla tape/Stans with several tires on S-XC rims (29er). Rampage and a couple of high volume WTB's were no problem. Folding crossmark 2.1 had most difficulty - needed good compressor and 2 1/2 cups of Stans because you'll lose a lot of juice until the bead snaps. On my last attempt one crossmark mounted well but lost some air overnite but not flat. Still need to mount the other tire today after work as the first attempt failed and ran out of time.

    All the other tires I could do in the house, no valve core removal, no mess and probably could have snapped the bead with floor pump, but not the crossmarks! Do it outside and prepare for a mess. Also watch for juice on rotors as you don't want to get that mess in your pads.

    Good luck - it doable but not the best for first attempt.

    Had to ditch the CrossMarks after numerous flats. The sidewall is flimsier than tissue paper. Oh well it was a good excuse to go tubeless.

    True. I think the 2.1 crossmarks will become dedicated tread for riding the long stretches of pavement to the long stretches of dirt road for those days I'm just putting in junk miles. Light and fast. Great with tubes when 60 psi pavement days are a callin'.

    First time the crossmarks came off I was surprised how flimsy/twisty/loose they were.

    So - the rimtape was not yellow stans...

    Update to tubeless conversion of P-XC wheels

    I just got the Stans "flow" rim strips and had just enough time last night to install on the frt wheel and convert to tubeless - tire = Panarace Rampage 2.35 that was previously installed for a couple rides with tube. I did it with a hand pump and referenced the Stans video instructions for help. The key was definitely the soapy water on the bead. Wheel has not lost a lb of pressure since last night.

    The flow rim strip is definitely the idiot proof way to go... coulda done cheaper ghetto, but had already ordered em.

    Will convert the rear later and than ride... for reference its an Ardent 2.25 - also ridden with tube.

    Rear was faster and easier - experience I guess

    Went for a good ride after mounting - after letting some air go on the trail - based on "feel" = perfect!

    The flow rim strip and stans brew works great, easy and still no air loss a full day + later!

    Anyone know what the spoke tension should be at on the P-XC's?

    The best quality of the stock wheels is the rim. With their high profile and shorter spokes, they keep lateral flex to a minimum. I'm curious about the rim weight to hub weight too - someone posted rims only as 490g on page 1 of this thread which isn't bad. I'd guess heavy hubs as the weight culprit. I absolutely love my XTC1 as is but wouldn't mind lighter wheels if they retained the same qualities and were a significant weight savings. Great bike.

    Duke of Earl posted in this thread the following....

    P-XC2 profile inner bead width is 19mm with a sleeve joint. The rim weights are: 440g (26") and 490g (29") give or take 10g. 24mm tall profile allows for a slightly shorter spoke which helps manage the overall wheel weight PLUS increase the stiffness slightly.

    S-XC2 profile inner bead width is also 19mm with a pinned joint. The rim weights are: 460g (26") and 520g (29"), also give or take 10g. A slightly shorter profile is not nearly as radially stiff which does allow for slightly greater vertical compliance.

    Wow 490g for the 29er P-XC2. That's about the same as the stan's arch.

    How it look the first version P-29 rim (XTC models 2010) in comparison with models above? Maybe somebody show the photo P-XC2/S-XC2 without the tire?

    Thx

    Great thoughts in here. I have a question on the 406892 Rhythm Tubeless Rim Strip-Symmetric method. Will this work on the 2010 P-XC. They are not the P-XC2. Thanks in advance.

    Bontrager rim strip

    So I just did the bontrager rim strip method to my 2010 p-29's from my xtc2. I have not put Stan's in them yet but currently sitting at 60psi. Beads made pop when engaged. Aired up with hand pump. I will add Stan's tomorrow.

    So, the tires held air all night with no Stans at all. I pulled the core from the valves, and put 2oz of Stans, soaped the bead and aired up again with hand pump.POP POP beads seated again, all i can say is the conversion is super simple with the Bontrager stips.
    Now if these dang Specialized Captain Controls would stop leaking. I am almost all sealed but really? 3days of shaking and flipping. only lost 10psi in 3 days, but you can still see the bubbles from a few spots on the sidewall.
    I think I am going to add 2oz more to each wheel, due to the massive amounts of pin holes on the sidewalls in the first couple of shake downs.

    i just got my 2012 anthem x 29er 1 last week and i wanna go tubeless.. im from the philippines and im not sure how to go about this as i havnt done tubeless before at all. i also have the Giant P-XC29-2 rims. my tires are Schwalbe Racing Ralph, 29x2.25 EVO Folding TL Ready.

    so my question is. what exactly do i need to go tubeless? do i need the stan's tubeless kit? or can i just buy the stan's sealant?

    also are the hubs that came with my wheelset ok? ([F] Giant Tracker Sealed/CNC w/ 15mm Axle, [R] Giant Tracker Performance, 32h) <-- according to website. i ask because i have a spare set of hope pro 2s that i want to use to replace the factory hubs.

    I would go back to the post by mudmav and follow his directions. This was super easy. Took me less than 1hr to do both wheels.

    No-Tubes.com is Stan's web site. It has instruction videos.

    I did a pictorial guide of converting my wheels using Bontrager parts, stans sealant and Specialized tires:
