Going tubeless, i hope

[dmonkey]

Can you say 99% of all 4wheel vehicles ever? I cant think of higher forces on a 250-700# bike ever being greater than a car?? It is and was a pretty sweet system, just mostly new and different, and maybe better...

99% of 4 wheel vehicles don't have forks, that's a big difference.
Bicycle forks are very light, I imagine you don't feel a balance difference on that Cannondale? On a motorcycle you'd have a lopsided setup that either needs to be made of very expensive materials that are strong and light weight (same as that Lefty setup), or it would need a counterweight since motorcycles are balanced upright, which isn't the case for 4 wheeled vehicles where there's one on each side.

also, car/truck suspensions are double shear on the spindle. yes, even on strut suspension considered double shear. nowhere near a close comparison in regards to how the loads are handled.

I rode both a suspension lefty and a Hooligan lefty rigid, and you don't feel a difference. Feels just like a regular bike.

How do you handle the valve stem with the tape? And do you use the normal tubed or change to tubeless tires?

Update, complete failure on the gorilla tape on back wheel, while on a ride today I lost enough pressure to cause tire to break the bead at slow speed. I was able to air it up and ride home stopping a couple times to add air, several nipples appear to be leaking I suspect that the pressure was to much over time for the soft tape, I've ordered some outex and I will post pics of the rim when I take the tire off.

would you consider trying the split tube method first while you have the tyre off?

 

[bryanchurch06]

My only opposition to it is needing a tube every time I change tires, I will be changing tires 2 times on the trip, also it doesn't prevent a torn valve stem leak

 

[Kritou]

Understood - tho’ on the valve stem front the remaining tube is firmly clamped ‘twixt bead and rim over the whole circumference - so I can’t see any possibility of the tube moving and tearing the valve stem/tube interface

 

[dmonkey]

With the tube pinched in that manner, if you do get a significant puncture and lose pressure the bead is likely to unseat. At that point wouldn't you need to both plug the tire and replace the tube with a new one to split?

 

[bryanchurch06]

Got the tire off, you can see the failure points at the nipples, any suggestions for glue removal?

Alcohol seems to work

Rims clean, took a solid hour with alcohol and a scrubbing rag, Going to use brake cleaner before I install outex.

A valid comment and one reason why I still carry an o.e.m tube in the tool kit!

Virtually all my flats have been caused by nails/screws and with my tubed wheels the deflation has been immediate and fast. Over on YT QuasiMoto describes how his CT took a long screw through his tubed front wheel and straight down an embankment. My experience with tubeless tyres has been for much slower and controllable deflation as the air has to escape through the puncture wound rather than the nipple ends and valve hole

It looks from @bryanchurch06 photos that his air loss might have been fairly quick from those spoke ends? It would be interesting to hear more

In the meanwhile I ride in hope and expectation that with any further flat the bead stays on it’s rim!

btw I have the Fobo Moto Bluetooth tpms valve caps and they send a very attention drawing series of warning to my phone if the pressure drops below a certain figure. They have twice caught an incipient puncture on my previous bike

 

[bryanchurch06]

I aired the tube to 33psi before riding to the park 10 min away, bike went fully flat while I was going about 10mph I felt it bottom out and stopped with no issues, looks like I had a significant leak around valve stem, the napa valve stem did not have as thick rubber washer as the outex kit had which contributed I think.

Do you think there is any possibility that air managed to leak from under the Gorilla Tape and the pictured damage on the spike ends was caused when the tyre bead collapsed into the rim well?

If indeed it was the other way round could the spokes and their nipples have flexed enough to damage the soft tape?

In my rather uneducated opinion, I think the air pressure into the nipple cavity over time caused a leak. I had a similar issue on 1st installation from my tire iron hitting the tape and I had to patch that spot. I didn't take pics but I had some tire sealant in and you could see several spokes that were leaking however I now believe the main Leake was the valve stem around the rubber gasket. I'm going to order the Bluetooth caps you mentioned, do you have a link?

Alcohol seems to work

To clarify, was this a "a little for you, a little for me" or was this purely a, "using alcohol for cleaning" moment?

just on the rims, I can barely drink anymore and never while I'm working

I know that Aussies like to have a VB with their mates but drinking with your wheel seems a mite OTT …
