The Rabaconda is, without a doubt, the quickest and easiest way to change your tire! It is race-tested by over 80 top riders and factory teams across the globe.

Video transcript:
The first thing you need to make sure of is to have your tire changer set up according to your wheel size because this will allow the unique bead breaker system to function as it's meant to. I'm using an 18-inch tire for the demo and I already have it here set up at the 18-inch marker.

Okay, let's get to the business. When changing a rear tire, it's always better to keep the disc side facing up because this will give you more room to operate the tire irons.

There's less chance of busting your knuckles or getting hurt. Start with releasing the rim lock. Release it almost to the very end of the rim lock bolt.

To start with the dismounting, position the rim lock straight across from the bead breaker system. Grab a tire iron and use the straight end for dismounting. The straight end is easier to insert. It is stronger. And later, it is easier to get them out between the tire and the rim.

Grab the rim handle. Position the bead breaker as close to the rim as possible. Sometimes the mousse can be really hard and it’s so difficult to get the tire irons between there. The key here us to put your body weight as close to the end of the green lever as you can, simultaneously pushing the tire iron. It's best done with one quick and strong movement... like that.

Make sure the tire iron is right next to the bead breaker because there you would have the most space to insert it. Grab another one. Leave about a 4-inch or 10-cm distance between the tire irons. Repeat the process.
And the 4th one… 4 tire irons are mostly enough when changing a mousse insert. Make sure you have the bead breaker close to the rim.

Now, before you start flipping them, it’s always good to test if they’re nicely in there. If you pull and they don't slide out, then it's all good.

With really hard mousse, there's also one trick to get the tire irons flipped easier. You need to brake the bead from the opposite side. This will allow the tire to come over the rim more easily. So, have some pressure there. Grab one in the middle first If and the other one in the middle. If you grab the ones in the middle first, then those two here won’t slide out. If you start with the one on the side, the other ones might slide out easily. Now you can see the straight ends come out easily between the tire.

Now that you have about a quarter of the tire dismounted, it's time to flip around the tire. Flip around the wheel… the sector which is just dismounted, position it under the bead breaker. Grab the handle again and start pushing the tire off.

First, push off the lower bead and the mousse so it's completely outside of the rim. Once it’s outside, again, start straight across from the rim lock and start pushing the tire completely off. Put some pressure here.

Here I have a really slippery tire so what you can do here is stick one tire iron here and push it off. Once you have it standing on top of the rim lock, now it's not possible to push it over like that because you're pushing straight on top of the rim lock. The guiding system should be brought here so you can simply slide it over the rim lock.

Now it’s actually possible to mount a new tire without taking the old one off. But I'm mounting the same tire here for the demo purpose. When mounting a tire with a mousse insert, make sure you have it prepared well.

Great video, it’s nice to see this done slow and explain the steps, most of the videos are showing how fast, thanks

Dude, that was the absolute best tutorial on a mousse bib tire swap I've seen yet.

[mikariikonen]

Thanks for this highly informative video!
Earlier I had changed less than 10 tires in my whole life (with inflatable tubes) using tire irons. Now that I have mousses, I purchased the Rabaconda. Thanks to THIS video, I was able to replace the tire with minimum effort. To be honest, it took more time & effort to squeeze the old slippery bib inside the new tire than it did to install the tire on the rim!
The only difficulty was when removing the tire from the rim at the rimlock - somehow managed it anyway.

Than you so very much for this excelent instruction-video Tonu! I bought the Rabaconda and to change the tire of my Beta 390 is so much easyer! You make a very good job and the product is realy very good!

[TheGirlOnABike]

Fantastic tutorial. Thank you. Now I'm going to go practice!! Home lock down entertainment

[robddickinson]

Superb tutorial Tonu, many thanks for posting.

[Willy_Milano]

If you break the disk doing that, it probably was a slice of cheese and not a brake disk. Good job!

[srqFF]

That machine looks pretty great! Good job

[christhompson]

Excellent video, people moaning about brake disc have obs never changed a tyre ever

[jamespolucha]

Great video, I know the other videos want to show how fast it works but you go nice and slow so we can see how it’s done and why, thanks again now I’m going to practice on mine, how often do you lube your mousse ?

[TimCullis]

This is better than other videos but I can't help feeling it's an awful lot easier mounting a used tyre and mousse than a new one. I would love to see a video with NEW Michelin Desert Race tyres and NEW Michelin Bib mousses. I laugh when I read "an easy 3-minute job", I have never managed less than 3 hours and the last two times I gave up with the Rabaconda and took the wheel to a professional tyre company. I am now about to do the same.

[darrenlegallais]

Thank you very much for this awesome instructional video... I take it the three minute is if everything is immaculate and the new tyre and mousse is ready to go LOL 😂

[blazter]

Mine arrived today. Changed my front and rear with mousse for the first time. My biggest problem was to put the first side of the tyre on. Showed at 7 min 12 sec. Even small steps were nearly impossible with my Metzler Mc360 140/80-18. In every video I saw it looked as a very easy step. Any tips? I used straight leavers. Yours doesnt arrived today. Everything else was super easy love the product!

[clintanthony]

Is there a video showing how to change a tyre/mousse with two rim locks? It definitely complicates the process.

[greatfallskam]

I just attempted my RABACONDA tire changer on a tubed 21" inch front tire ( 90/90-21). Mitas E07 tire. This is my first try and had some questions.

1) I noticed the bead breaker tire support adjuster moved slightly off 21" inch mark. I think made it hard for me to removing the tire. Anyway to keep that leg from moving?

2) With a tubed tire, can I leave the tube in wheel I dismount the tire, or should I try to remove it before attempted to pop entire tire off?

3) I assume it is OK to use some kind of lube to break bead and remove tire?

4) The you flip the tire to remove it, should the saw tooth edge of the bead breaker be pushing the very edge of the tire ( closest to rim )?

5) When I come to mount my new tube tire, should I install the tube with 5 PSI and mount it like a mouse?

Thanks.

I bought a used bike, I then found out that the bead on the rear tire wasn’t set all the way and wobbles slightly when driving. The bib is already in it. How do I set the bead with it already in there

[pipefitterdirtbikerider]

It feels like there’s a tiny tiny gap by the bead lock

[strokenrg]

OMG. Why. Why. Why haven’t I seen this before.

[maxlieberman]

I can’t seem to get the tire on. I can’t hook one side under the bead lock… it just won’t stay. ANY HELP PLEASE

[SeatTime]

My riding has a better chance of breaking a disc rotor over my inabilities while changing a mousse.
