How to Change a Bib Mousse Foam Insert Tube - Full Dirt Bike Tire Change Tutorial by Rabaconda

Hello, fellow dirt bike lovers. This is Tonu from Rabaconda here. In this video I'm sharing my experience about how to change a tire with a mousse insert, also known as foam insert or a bib mousse, which is a truly great invention for riding but changing those can be a real headache. However, with proper tools and good working techniques it can actually be pretty easy. I'm using here a Rabaconda 3-Minute Tire Changer and a set of 5 Rabaconda Pro tire irons. These tire irons can be used with both ends. The straight end is really good for dismounting a tire while the curved end makes mounting the tire much easier. I will get into more details about which end to use when later in the process. 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 oneů 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 then 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 wheelů 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, 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. I'm not going into much details about how to prepare a mousse tire in this video. Just make sure before mounting that you have removed the excess mousse gel from the tire bead. You don't want to have them too slippery. It's always good to have some special tire mounting spray to make the tire fitting easier. Here, I just have some soap water. It dries off later and will cause no problems. When starting, it's good to have a foot on the base frame. This will give you more stability. Position the rim lock in front of you. Grab the tire. If you have a rotational tire, make sure you're mounting it the correct way. Step one is to get the tire bead behind the rim lock as far as possible. Try to get it to the drop center of the rim. You can support it with your knee so it won't slide back, and push on the tire as much as you can. Keep some tension with one hand, grab a tire iron. You can do this also with two. I'm used to doing it with one. It works just as well. Before mounting the upper bead, the mousse should be completely in the rim so you won't see itů Like that. Position the rim lock here, under the bead breaker system. Put the first tire iron close to the rim lock here and fix it under the hook here. This nice little hook gives an extra hand, keeps the first tire iron in place. Take another 4 tire irons and start mounting the tire. Some soap water never hurts. You have less chances of harming your tire. Take 3, keep the 2 in one hand, operate with another. Once you're about one-third in, take a tire iron with a straight end and stick it right here. Take a few bitesů grab another one here. Those 2 tire irons will work as sliders once we get to the last section of the tire. They will help guide the tire bead down to the top center of the rim, which will allow us to safely mount the last part of the tire. The closer you get to the end, the smaller bites should be taken. As I'm getting here, you can see how the tire nicely sucks in there and we can safely mount the tire. If we hear any cracking from the tire, you probably don't have it deep enough on the opposite side and might harm the tire. Once you get closer to the end, you might find that it's difficult to get the tire irons in. What helps here is if you come back with the one you have here, release the tension, get the second one in, and then 1, 2ů Now, for mounting the last section here between the rim lock and the rim, there are different ways for doing this. I'm sharing how I usually do this. For me it always works well. It takes maybe a few tries to get used to the move but for me it always works. Step 1 is to position the bead breaker on top of the rim lock as close to the rim as possible. Step 2 is to lever the tire iron from the brake disc, push it in. Step 3 is to push down the tire like that. I've heard people complain that you might break your brake disc or bend it. Well, I've been doing this for years. I've seen pro riders doing this at competitions and I've never heard of any problems. It's a completely safe way for doing this. Before heading out, make sure you fasten the rim lock nut. Remove some soap water so it looks nice and fresh. I hope the tricks I've shown you will make you a better tire changer. In case you have any questions leave a comment and subscribe to our channel.
