I learnt the hard way - never use Stan's

[Iwan Kemp]

I've been using Stans since since 2006. Various rims, tyres, bikes & push-ups and I haven't had a single with any single one of them.

 

It has saved my bacon and many epic rides with it's quick and hassle free way of sealing a puncture. Since 2006 I've only had to walk a bike back to the car twice. First was in 2007 on a Spez wih stupid light tubes and flimsy sidewalls and the second was my Vipa earlier this year in Jonkers, but that was thanks to a massive sidewall cut on non-snakeskin tires.

I have Maxxis Monorail's on my XT rims with Stans in and without rim tape. Would you guys recommend that I put rim tape on?

[GhostSixFour]

Was brand new XT rims bought of a fellow hubber , fitted new valves, filled with Stan's and rode for about three months, noticed a slow puncture on the front wheel. When I removed the tyre all the Stan's was at the valve, when I scraped the Stan's away I found the leak :-(

 

You do realise that the Stans were just doing their job? I.E. sealing the hole, thats why it was accumulated,,,

Hmm - are you sure you were using Stan's . There is no way an ammonia like substance like Latex can eat Aluminum alloys, so you have another problem. Maybe you need to investigate where that hubber that you bought from got those rims and what their provenance was....

 

Nail ==> head...

I'll put my money on the fact that those rims were in fact NOT "brand new" ...as sold by hubber...?? :eek:

Yea second rim was still perfect . I just checked I do have two different valves one silver thread and the other one has copper/gold colour the ones rubber section does sit better in the rim.

 

Might be that I did over do the tighting of the valve In order to get the valve to seal.

 

What is think:

 

AL that is anodized is hard and does not react with Stan's , as soon as there is any imperfection in the anodizing the Stan's attack the AL, so in my case when I over tightened the valve I damage the Anodising at the valve hole giving the Stan's a place to attack .

 

Next time I'm at a bike shop I'll buy a small bottle of Stan's I'll then place on piece is bare Al and one piece of anodized Al in a bucket of Stan's and report back after a few weeks

 

I for one would be VERY interested in this experiment's outcome...

 

Where is JB when you need him???

[Cassie]

Google galvanic corrosion. That what happened there. Most likely the one valve was cheaper "mild steel" type and then touch the aluminum. Add road dirt/salt and water and rest is history

 

Now THIS i'll believe...probabaly the best explanation thus far...
