Bib mousse installation
« on: October 12, 2012, 07:40:57 AM »
Anybody out there have any experience with bib mousse installation?  I picked up a front application )pirelli) and thought I would try it.  Of course the installation instructions were missing....  I have been changing tires for decades now but couldnt get the d*mn thing on! ><img src=" title="Angry" class="smiley">  it seems like the rim lock may have been the problem.  Does anyone know if you need to retain the rim lock with the bib mousse?

Vice grips and LONG tire irons. Clamp the vice grips on the rim on either side to hold the bead in place while you pry the tire on.

Thanks for that Sachs, but I shudder at the thought of vice grips on my pristine rims! :o

I did find some good stuff on the web but there is much more involved than meets the eye...  I think I will go back to the tried and true method of small tire levers and heavy duty tubes!

I think I can get it on if I dont use the rim lock; but surely the tire will rotate with all the lube required....

At the offroad races you'll see guys using vicegrips, not nice but by far the fastest way to change a tire.

Plenty of companies make "bead buddies". They hold the tyre bead down into the rim. Most good ones, also clip / key onto a spoke to be secure. Motion pro have pretty blue alloy ones - but there are cheaper steel ones out there.

You can also use things like 'G' clamps to squash the tyre bead down.

I think child birth is easier than installing a front Bibmouse.. Many women would disagree with me but not many women have been through the installation process.

It sucks.

When they first came out, I would go to the local shops and pay them to install it. Usually quote me like $5. They would not do it again for $50!

So basically I did this: First, I cut a valve stem from an old inner tube and using rubber cement, glued it in the rim.

Mount the rim solid to something. A tire changing station or enduro tire change thing preferrably. I cobbled one togeter out of old wood and bolted it to my bench. Be sure it and the bench won't move if an elephant hits it (because that is about the effort you are going to require!)

I then greased the inner tire and mousse up real good and put it in the tire with one side already on the rim. Then with vice grips, sweeze the tire together and clamp it tight. Be prepared for it to slip off since you greased it up real good. A good deal of cussing will ensue so be sure little ears are not standing by. Next, crimp the bead in the lowest part of the rim. I used one of those handy pistol grip kind of clamps as it is plastic and won't scratch my (already scratched) rims. Zip tie it in place (remember you are loobed up real good!). Now you an a buddy (a much bigger buddy preferrably) start working the longest tire irons you can find around the tire, You are going to hear it stretching, straining, and tearing. Iron's will fly (remember the loob), tempers will flair and blood will spill.

Once it is on and you remove the wheel from you contraption and pull off al the clamps, you can now (if you have a good compressor) blow air into the rim through the valve stem to help seat the bead. Yes, I still run rim locks. They are just an added pain (and more clamps and zip ties).

Drink copious amounts of beer, keep a tire iron handy and don't get any ideas about your buddy all covered in lube. If you followed my directions, you chose somebody bigger than you and he may not take kindly to your advances. Conversly, that is what the handy tire iron is for.

One last bit of advice: Tire Balls. Although the concept of putting a tire already full of air on a rim is the same, it is easier with Tire Balls and you can contro the "feels like" air pressure to some extent. I have used Mousse but rarely can I re-use them more thna once or twice. I have used Tire Balls over several seasons and only replace the individual poped balls when I change the tire.

I freaking hate these things but they will save your season if you are serious about off-road.
