Hmmmmm.. Good luck with that. ;)

Think I'm gonna stick with a tube in there and a spare in my bag :)


x2 :lol:

seems a lot of grief and i'm not sure its needed round here as the only rock garden is on the olympic course ! I love new technology and normally work at getting it right but this just seems a PITA.


X3 I'll stick with my tubes... Swopping tyres is now down to about 15 minutes and away I go....

I know I know all you tubeless fans will unite in flaming us tube lot... Just out for ease.. And when I can smuggle a new set of wheels home I may then just convert one to tubeless... Until that time... LONG LIVE THE TUBE!!!!!!

I have been pricing up a set of rims, hubs and spokes to build a set of carbon wheels :wink:

Jamie, precisely what she needs to know, F'all.

Spence, its the way toward, don't give up yet.
I just did my front wheel again as I've been running a tube in there since before Xmas when I broke the valve over at Evans. Plus other fettling.

Tubeless, that's the way! After tonight's ride wheels are fine. Massive difference in rolling resistance. It's like riding flat on uphill parts. Amazing!
I put soapy water, agitated wheels and left for a while horizontal so the sealant would cover any possible air leak. Don't know if the soapy water had helped but leaving them horizontal is vital.

By the way, I think I don't have the removable valve but it was fine to add the sealant for me without messing up.

its cool you're getting it sorted but the physics are really getting to me, you filled the tyre with sealant (liquid) then swished it around the rim for coverage which is cool then laid the wheel horizontal so all the sealant runs to the lower side that also has the weight of the rim pushing down on it, unlikely to be air leaks there but more likely to leak on the top side where there is now no pressure ? :wtf:

Also the reason for the washing up liquid is because its sticky and thicker than water and air so as the water dries the soap creates a simple seal to stop any sealant creeping out in the first instance but it soon dries off.

I'd like to think i'll wait until the system is improved but knowing me if some spare cash comes up i'll probably have a go LOL

Close, the tyre is still under pressure when layed horizontal, letting the liquid sit on the sidewalls and rim creating a seal. doing this on both sides covers the inside of the tyre.
the resason you use a combo of washing up liquid and water is to create a seal and also to lubricate when initially seating the tyres, not neaded once already seated.

The system works well as Javi has just found out, its just a faff the first time.

Going tubeless is like riding a 29er or going clipless. It has some fans and some haters. I personally am a fan

I rode South Africa for over a month and never had one issue - Rock gardens, thorns as thick and as long as your finger couldn't stop me! Not even the locals spears could pierce my Maxxis Crossmarks....(slight exaggeration) Although their hunting dog did piss on my tyre.

But then I got my Specialized and there is a reason Specialized leave the sealing up to the new owner.....its forking shite. I have never had any issues sealing, seating, inflating - or any other problems until those forking Renegades. Worst tyre and rim combination in the world.

So I think the problem with tubeless is finding a good wheel and tyre combo, if you get that sorted you will love 2bliss!

Hopes and Maxxis = good combo
Hopes and Bontis = good combo (such a tight seal its impossible to get off.......blah)
Hopes and Contis = not bad
Specialized and Specialized = bad combo!!! lol

Just bought a stans conversion kit on fleabay which I'm going to attempt to fit on a pair of mavic 1.17 mx ( I think) . They're the original rims that came with my 2005 giant vt2. I'm putting a pair of schwalbe hand dampfs on them, and I'll post how I get on.

I ghetto'ed my Mavic 721s with Hans Dampfs last month. Tip - make sure you air up the tyres (with tubes) once you get them and leave for a couple of days. They should air straight up after that.

I used Mavic 721s, Schwalbe AV7C 20" tubes, Hans Dampf trailstar on the front and pacestar on the rear - they really are great tyres..

I'm running about 28psi f&r and haven't had any problems at all - am loving the extra grip over the surrey hills roots. As I was a serial pinch flatter with anything lower than 38 psi in the past I am well chuffed. Also shaved a load of weight off the pitch.

Worth pointing out I didn't bother with the soapy water, keeping the tyre horizontal or any of that crap - schwalbe tL tyres don't need it - as soon as they take air, its done. If you get them from actionsports.de they turn up within 48 hours and are much cheaper.

I have been running Stans No Tubes no all my bikes for over 6 years. And I will never go back to tubes.

At first it was a messy pain getting them set and sealed.
After lots of swearing and mess I started to use Co2 cartridge to set the tyre. With lots of washing up liquid and water.

I have run my High Rollers on Mavic 321 as low as 10psi on black run's with big rock gardens and drops. And the grip was amazing, and what I lots in rolling speed I made up with the speed I could carry throw bends and technical sections.

The only problem I have ever had was when my 1.8 mud tyre on my XC came away from the rim. But I fooked up the jump so I was going down anyway.
But I got up popped some air in the tyre and finished my days riding. And the same tyres was on all winter.

Ta for the tips, can't wait to give it ago so I can try the hans dampfs out. Slipping and sliding all over the place today on an old huchinson scorpion up front and a panaracer razer at the back.

Been using Maxxis LUST tyres on Mavic rims for four years now, never have a problem with leaks.
May help that I used to fit tyres in the army years ago so know how to do it. Use proper tyre soap, nothing else, don't use tyre levers just your hands, levers will ruin the bead. Use a fast track pump and pump up to max (60-70psi) until the tyre pings on the rim, then leave for a few hours until deflating to 30psi (or other desired pressure). The ping is important.
