- Stans tubeless – do I ever bother again?
I’ve had this rim from new and have used Stans’ tubeless solution with it. The thing failed on me when a nipple broke, and once the tyre was off I noticed salt around the valve. Took the valve out and a chunk of rim came with it. It was also smelly and just horrid.
My question is, should I avoid Stans forever and ever again, or is this a one off and I should just suck it up? It seems pointless that two products designed to work together actually feature a fluid that rots the rim.Posted 4 years agoNorthwindSubscriber
Any trace amount of ammonia in Stan’s sealant will evaporate soon after it is injected into the tire. We have found no damaging effects from our sealant even after years of use. Any oxidation in your rim will just as likely be caused by riding in wet conditions or the humidity in the air. Although tape may not be necessary to seal your rim, you may add one layer to protect un-anodized or scratched areas of your rim from oxidation due to moisture in the sealant.
Northwind says, how likely is it that the 2 things are completely and dangerously incompatible but you’ve never heard of it happening before?Posted 4 years ago
Well, yes, it could be a million and one things, all completely my fault…. but my point is, it has just rotted away and yes, I am blaming the two products. I’ve got several sets of these things, so have invested heavily into the system. Quite frankly I’m hacked off that the rim had the temerity to just rot away before I had the chance to break it on a rock or such. That’s just poor form.Posted 4 years agoThrustyjustMember
Investment? I use a roll of insulating tape and a couple of valves for a tenner. If I wanted to change back, Its just unscrew the valves and fit a pair of tubes. Cant see how that’s a costly change, unless you spent money on stans kits ?Posted 4 years ago
Sadly, certain parts of a bike is lifed and a lot of people disregard this and expect it to last forever. A rim change is £40 ish for a rim and an hour of swapping spokes, so not the end of the world. Maybe the rim has been lifed?quantockspaulMember
I’ve just discovered very similar looking corrosion on one of my crests with leaky valve and nipple eyelets having used them with Stan’s for 3 years – the other wheel was fine. I plugged it with silicone sealant and then re stan’d it and it’s fine again. Fenwicks airtight did nothing but stain everything it touched blue.Posted 4 years agoNorthwindSubscriber

£70 just for the rim. I expected more in the way of life expectancy is all
And so you should, that’s what we’re saying- you’ve got something weird and unusual.

Sort of wondering.. if you wanted to run tubeless, why not buy a manufactured tubeless rim where you just put a tyre on ?
Like a Stans, what he bought?Posted 4 years ago
2 to 3 year old Stans ZTR rim, Stans sealant used. I like to use normal tyres, hence the sealant.
OP, if you’re blaming the sealant, please explain how it has got to the other side of the rim tape to rot the rim, yet the air inside the tyre can’t escape?
Red herring comment? The sealant goes between the outside world and the inside air – the valve being a notorious fun spot when trying to seal these things, hence the various posts about the use of pliers. All you have here is a little rubber bung; some fluid always escapes.
I’m going to put this one down to a manufacturing defect and move on. I’ve never had this happen with any other rim and I’ve been tubeless for over a decade, hence why I’m slightly miffed. As stated, if it had been down to some trailside mishap, it would have been part of the experience that is mountain biking, and I’d have been happy. But I look after my bikes, so for this thing to turn to salt whilst sitting in the Man Cave is just not cricket.Posted 4 years ago
Not a lot of fuss – just a question on a forum is all. Kind of got my answer; Stans is OK, mine just sucks, chalk it up. I’ll junk the rim and get another. No biggie.
Little hole? It’s almost the same size as the valve hole. Dunno, but I kind of like a bit of structural integrity in these areas.Posted 4 years agomountainsofsussexMember
One more thought… Are the Stan’s valves steel or brass with shiny nickel coating or something? If they are steel, I suppose that in conjunction with some nice salty water, you could get competition corrosion of the aluminium rim in contact with the steel valve… Perhaps aided by water being trapped behind dried latex?Posted 4 years ago
