[RBW] Re: Valve Stem eating Synergy Wheels

[cyclotour...@gmail.com]

Thanks for the update, Edwin! 

FYI, I didn't install the metal sleeves I bought. I did spin a valve nut 
all the way down before installing the tube. It hasn't been that long, but 
no problem so far!

Update:
Had another one of these valve base flats. Different rim (CR18), 38mm 
Vittoria Randonneur tires.
Tube: Kenda. 
Replaced it with one of the Riv-sold Rubenas that looks like it has 
reinforcement at the base. And I slipped an extra piece of tube over the 
stem.

Re: [RBW] Re: Valve Stem eating Synergy Wheels

[Edwin W]

Dareck,

I've been waiting to hear of someone putting the nut on the INSIDE of the rim. 
Makes sense to me, but I wasn't sure. 
On closer examination, I can tell my valve hole is a bit wider than the usual 
so there is more wiggle room. I redid the rim tape and cleaned everything up. 
Might try the nut on the inside so the valve stem base does not get into the 
hole. 

Edwin

I've screwed a presta nut all the way down against the base of the tube
before installing the tube so it was on the inside of the rim.  It looked
like the rim was chewing through the tube. I didn't have any further
issues.

If you have corrosion, odds are, it has nothing todo with dissimilar 
metals.  It's because you have a place to collect gunk.  
However, you could have fretting, which is a combination of contact fatigue 
and corrosion promoted by vibration  .  



Which gets back to my o-rings being the solution.

Hey cyclotourist - and all

Sorry to come in late on this.  Velocity replaced my rear rim.  

The first time I saw it seemed to be an electrolysis issue which is how I 
descibed it to them. They no longer use that particular material on newer 
rims.  The original set were Aeroheads made in Australia.  They have 
replaced quite a few evidently.  They were quite nice about it.  They even 
offered to re-lace the wheel for me, but I was in a hurry at the time.

Interesting theory about tube valves though. ;)

I don't know about Bonty, but Novara tubes are made in China vs. Taiwan for 
Q or Indonesia for Schwalbe.

Same here. My LBS used to stock Continentals, which worked great; I 
typically ran them for 3K-5K miles. Ever since they dropped the Contis and 
replaced them with Kenda/Q-Tubes, the stupid things blow all the time. I've 
been going out to RBWHQ for Contis for the last year, but I just noticed 
that the Rubenas are back in stock and so the Contis are gone. I haven't 
quite mustered the consumer will to spring for Schwalbes, but that's the 
logical next step. I'd been thinking of getting a pair or two of Challenge 
Strada Biancas from Wiggle, so that's a good opportunity to load up on Euro 
tubes for cheap.

I'm not sure who the OEM is for Bontrager or Novara (REI house label) 
tubes, but I assume they're also Kendas. Eccch.

Schwalbe seems to be the way to go! I had some on a bike I sold, and no 
problems. Of course the Q-tubes are problem free on the other rims as 
well... :-)

The scuttlebutt is that they were the last mfr but no longer make them --
much noise about 650C latex on Tri and Recumbent sites. At any rate, I

If you don't mind pumping at least every week, Challenge cross latex tubes

Re: [RBW] Re: Valve Stem eating Synergy Wheels

[cyclotourist]

Yes, could be bad luck. But kinda' weird only one wheel giving me this
problem, even intermittently. I'll try these sleeves and see how it work
out. Have to drill out the hole a little to get them to fit. What could go
wrong?

And yes Q-tubes are usually Kenda, but I think I've seen a few other mfgs
as well. They all have removable valve stem which is kinda' nice.

 The O-rings might be a fix. But put on the inside of the rim.

Re: [RBW] Re: Valve Stem eating Synergy Wheels

[David Banzer]

The product you linked to is for using presta tubes in rims that are 
drilled for Schrader valves.
Definitely seems like the braking force on the front wheel factors into 
this. Or you just have bad luck with tubes.
The Q-tubes, I believe, are just repackaged versions of Kenda or similar 
maker. I don't believe they're anything special. I've used them myself and 
had no problems though.

hope that works for you - it's certainly going to reduce bending moment on 
the valve stem at the rim opening

[RBW] Re: Valve Stem eating Synergy Wheels

[Bill Lindsay]

I suspect Kurt is on the right track.  You've got six bikes all running 
700x35-43 tubes.  Use this front wheel with the narrowest, highest pressure 
tire that you run, and see if it still eats tubes.  

I just scrolled back to your OP, and see that we're talking about 3 tubes 
in 2 years.  So, it'll take at least a year before you are even halfway 
confident that you fixed it.  haha, I won't hold my breath.

P.S.  Velocity will only blog about you if you ship them your wheel with a 
note that says "it failed, replace it"

[RBW] Re: Valve Stem eating Synergy Wheels

[Kurt Manley]

I have had a similar problem with stems getting torn. It was after I 
switched to wider tires and the valve stem would consistently tear from the 
tube. Usually when descending a hill where braking forces were high. Like 
you it was always the same rim. I stopped using it as I figured the tires 
wire too wide and causing the issue. On mine the rim tape eventually 
started to slip as well. Never switched back to skinnier tires to see if 
the problem went away just changed the rim for a wider one.

Re: [RBW] Re: Valve Stem eating Synergy Wheels

[cyclotourist]

Did changing to higher end tubes work out? You and David both hint at the
tube being the culprit so could be. I'll try getting a nicer one (of course
just put in a Riv order yesterday...) and give it a try. But even if that's
a fix, shouldn't a rim not cause a problem like that?

I've had the same problem with a VO rim. I don't have many flats, and in the 
last five years and 10,000 or more miles over half have been valve stem on that 
rim. Do try Schwalbe or other higher quality tubes. It might not be a defective 
tube, but a rim that needs a higher "octane" tube, so to speak. 

Blasted rim!

Interesting thought. They are Q-tubes. 700X35-43mm.
But, the exact same tubes I have on six bikes, including the rear wheel on
this one w/ same Synergy rims. This is the only rim out of 12 that is doing
this???

What tubes were you using? It sounds more like defective tubes than a 
defective rim.
