I would still be riding singles on the track...cant beat 220 psi on a good set of track wheels.But on the road they aint bad...so far I have done 4 races on the front and 2 on the rear...only problem is I have cut my Sunday ride in half as I used to ride to race on the M7 and race then go back same way..but now I drive to the track as I dont want to trash my tires as they wernt cheap.

How much did you pay for the tires, valves and sealant?

I got them from LBS...$115 -120 for each tyre.$12 per valve,$20 roll of rim sealing tape,not sure on the sealant.About $300 all up.

It hasn't happened to me, but my physio (and Australian MTB champion) described what happened when she had a tubeless tyre blow up (read: explode).

Basically, her husband was inflating it to mountain-bike pressure only (I think they were going to 40psi for a quick ride on the road or so) and the tyre gave way and exploded. Loudly. It smashed out all the windows, left her husband deafened for a day and coated the room with Stans No Tubes...

They now always wear eyewear when tinkering with tubeless.

And now that tubeless is coming to road tyres, this thread made me wonder what effect a road tyre exploding at 120psi would have?

What's wrong with a little interior redecorating? Sounds like some ear protection while pumping is in order as well. :lol:

Well I have only had one puncture on my tubeless set up and that was slow enough that I could finish my race.But the rear DuraAce rim had a problem with the valve hole being butchered by previous owner.The problem being that the tubeless valve would pull thru into the rim because the hole was too big.So first time I filled the hole up with silicon and let it go hard and re drilled the hole.It lasted 10 weeks or so but eventually the silicon compressed and the valve pulled thru.So this time I used putty metal to shove into the hole and then redrill but i think it has put too much weight into that part of the rim.Combined with the tubeless valve it looks like it might put the wheel way out of balance....If I flip the bike upside down,then spin the wheel up to full speed it shakes the bike uncontrollably and even a hard hold on the frame wont stop it.
Cant even be bothered riding it...going to bite the bullit and buy a new rim!.Ouch!!!.

Apart from less punctures have you noticed much difference in the ride and speed?

yeah i am loving the ride on these tyres....huge difference in rolling resistance and snap out of corners.Less pressure makes bike handle better too.I wont be going back to tubes.

Just took my bike into the LBS...they said dont worry about it.Not convinced...I had it trued and will give it a go on a smooth descent...might be OK as it is the rear wheel.Would be fine with a tube so if I am not happy it will go on ebay.Not really worth a new rim when I can get a 2008 Tubeless DuraAce wheel for $380 from CRC.
