Tubeless - loss of pressure

[BDF]

Second the advice, remove everything of the rim tape, clean with paraffin or meths before putting new rim tape. You don't need to clean the inside of the tire too much, just pick away any balls of sealant.

Use meths or another spirits based cleaner, not paraffin. Paraffin will leave an oily lining which is not compatible with the sealant. (unless you clean the paraffin off with meths!)

Benzine is the best thing to use to get the old glue and residue off.

I was concerned that removing the stock rim strips would screw up the rims. But now have the go-ahead. Wheel overhaul time

[s14phoenix]

I second the motion to replace the rim strips with gorilla tape. I now use nothing else because nothing comes close to it. All this other tape is crap and don't stick etc etc.

 

and new valves.

I had those rims and had the same problem before I put in a proper rim tape/conversion kit. Those rims are not strictly tubeless friendly, but will work if sealed properly.

I would pump it to 50psi and try the water test again ...

 

I agree with NSBB...before replacing stuff unnecessarily but would just add the following:

 

If u can check it in the pool on the pool step where u can put some weight on it to flex the tyre side walls.

 

HEALTH AND SAFETY

 

Be careful how hard you pomp it.... you can pop the tyre right off the rim quite easily at not so high pressures... i almost deafened myself and got an earful of sealant listening for leaks after pumping it up to +/- 50psi (3.5 bar) when the tyre unseated rapidly (Rocket rons on Stans rim)

LBS + ZAR200 = sorted.

 

Seriously, too much effort for marginal cost saving.

Your other option is to upgrade your rims to proper tubeless ones.

It's not a cheap option though, but saves headaches and if it makes your riding more pleasurable, or less irritating, priceless.

 

2x rims = R1500-3000 (depending on the rim you choose) plus labour (and maybe new spokes at around R15-20 per spoke)

I would be cutting into next month's grocery money (read: beer money) for this job so would prefer the route of Ryder tape, Stans tape or, most appealing, Gorilla tape. Found a nice article making a great argument in favour of gorilla tape.  And I have just enough sealant left to top up and seal each wheel twice.

I see Evobikes have Gorilla tape available, by the way.

Just don't buy all of it, I want to fix my wheels too

 

2.5cm x 9.14m, seems the perfect width for tubeless conversion, and enough of it to allow for screwing up a few times.

If you go the gorilla tape route just pray that you don't ever have to take it off    It does not come off well and will leave a lot of glue behind and the tape will tear into little pieces.

 

I work with tubeless everyday and I would seriously recommend the Ryder.

[gerhardsnorbaard]

Already ordered gorilla tape online. Check mate for me.

[traildemon.co.za]

Builders warehouse stocks gorilla tape

[PhilipV]

I use gorilla tape on all my wheels.

While you are at the lbs buying valves, sommer buy a hand full of valve cores as well. And a Presta adapter so that you can pump the wheels at a garage.

Or drill two holes in a coke bottle cap, slap valves in there, add some rubber pipe and make a tubeless bottle bomb.

If the rims I want to use with the tubeless conversion have shrader valves, is it possible/safe to switch to presta valves? Or will it cause issues due to the valve hole size?
