Tubeless conversion with non-ust Schwalbe tyres

[markStockton]

As anyone had any experience doing a tubeless conversion with non-ust Schwalbe Racing Ralph 2.1 Evo's?

 

I know Big Ben and some LBS have had success doing the conversion with non-ust tyres, however I've also heard of some where the side wall leaks.

They should work fine. The sidewalls of the gatorskins leak, but I havent seen another tyre doing it. They might leak a little but the sealant will sort it out quickly.

I've got Racing Ralph 2.1's on American Classic hoops running a Stan's conversion and they work great - nice and light too

This sounds very, very promising. I think I'm off to my LBS for some tubeless valves and some Stans fluid.

 

BTW - I have Mavic X225 rims, they not marked as tubeless (UST) however they are sealed (ie - you can not see the spokes), I thought I'd wrap some fibre tape around them and use them as is with out a rim strip. Any comments or ideas?

You might have a problem sealing the lip of the rim. This is also where the rim strips helps. Give it a bash. Remember to use soapy water which helps the tyre slide and seal better.

FWIW - I would not do it without a rimstrip unless it's a real tubeless rim/tyre combination ....... but that's just me!

[markStockton]

I'm easily convinced. I'll try the new Bontrager rim strips then.

Mark, we have been doing tubeless conversions on Schwalbe tyres for just over four years now - no problems.

2 things should be  noted:

- it is much easier when done on rims that conform to ERTRO standards

- Schwalbe will not warranty a tyre that develops structural issues as a result of using "aggesssive" sealants. While many sealnt solutions work very well, they approve only their own sealant known as Doc Blue

Shamus, is the Doc Blue sealant available locally? If so, where?

it is available locally.

we supply most of the bike dealers, ask your LBS to order some if they dont have stock

I have a friend who did that conversion, but he warned me that if I tried it, it wont work i'm the wrong side of 80kg (tire burps)

[Troi Sport]

JPW#,

like you , I am also over 80kg.

 

I have experienced this burping when running the tyre at too low a pressure.

 

The sidewalls indicate the minimum and maximum pressures to be used and should be strictly adhered to.

 

as a rule of thumb, I like to add 0.2 bar to the minimum pressure indicated for every 10kg over 70kg

Burping is an indicator of:

 

1) Too low tyre pressure.

2) Hitting something unusually sharp or edgy.

 

As you can see from the above conditions, weight plays a role. The heavier you are, the easier you'll burp at a given pressure. Pump your tyres or avoid edgy rocks.
