Creating Tubeless Mountain Bikes Rims!

★The Merits of OUTEX-MTB Tubeless★

Better handling by reducing burden below the spring

Improved feeling of being in direct contact with the ground

Spokes and nipples are exchangeable

Uses the same American-style valve as clear tubeless kits

Elastic sealing tape makes air injection easy after assembling the tire

Liquid sealant blocks air leaks from the bead and prevents punctures

Cross Section of a Conventional Tubeless System

These specifications present no particular problems when riding on common roads, but during downhill runs, etc. in which air pressure is lowered, air sometimes leaks from the bead due to the effects of G-forces applied to side of the tire.

Cross Section of an OUTEX Tubeless System

Attaching 2mm-thick sealing tape over a wide area, including up the bead, strengthens the seal between the tire and the rim.

OUTEX-MTB Tubeless Kit - Support Rider Makoto Iwate Rims: 27.5 inch; Rim Width: 36mm (outer width) Tires: Schwalbe Magic Mary 27.5 inch ×2.35 inch wide Super Gravity

Prior to Using the OUTEX-MTB Tubeless Kit Currently, I am using the existing NOTUBES Tubeless Kit with 27.5 inch wheels, but I have been having trouble with it as it’s hard to seat the bead properly and the tires lose air overnight, and so on. Also, as mentioned in the blog, commercial products only apply tape in the center, so the sealant rubber only sticks to the uneven spots on the tire and rim. This creates a weak seal, which makes me nervous that the air pressure might drop overnight or that the bead might become unseated. I deal with this using plastic tape, but that only works on the day that I apply it. Also, I want to use wide MAVIC rims, but they are not made to be used tubeless, so I forced a seal by injecting twice the amount of sealant, but…Air often leaked out when the bead was pushed in due to G-forces applied from the side while riding. So, I tearfully ride using a narrow rim that is made to be used tubeless. After Using the OUTEX-MTB Tubeless Kit Just to give you a race report, I entered the Elite Class, which is the highest class, and in the preliminaries, I had some mechanical troubles, so I barely qualified in 30th place (out of 55 riders). Due to the mechanical troubles in the preliminaries, I wasn’t able to do my best in the finals. I made lots of mistakes, crossed over the line several times and ended in 25th place. I used OUTEX Tubeless for three days. I put in 50cc of liquid sealant. I was left with a good impression as the bead seated right away as soon as I attached the tires, and there was no air leakage. I changed the tires three times during the three days with no problems whatsoever. I had no problems during the preliminaries or the finals, and the course was hard on the breaks, but I didn’t lose any air pressure at all, which means that the air didn’t leak. I hit several rocks, and my rim was sorely bent in two places, but even so, the air didn’t leak, and I was able to finish the race. When I removed the tire, I saw that the soft tape had slightly changed shape, but the bead seated again as soon as I changed the tire. As one of the usage conditions for the tires, I used them at 1.5 kilograms of pressure. The tire never came unseated. Even this was no problem. This is a big enough dent that current mountain bike goods would leak air. And so far, that is actually what has happened. However, this product is highly trust-worthy, even when using it for races! I had a race yesterday, and I noticed when I washed it just now that the air hasn’t leaked out. Handling Tires are lighter without a tube than with, so it’s easier to pedal, and when breaking, the breaks work well due to the lightness of the wheel itself. In addition, it doesn’t interfere with the tire’s flexibility, and being able to make use of the tire’s flexibility provides a smooth ride when cornering. It is also good that rim hits do not cause punctures, as there is no tube (when using liquid sealant)! http://wakitasoft.com/Timing/Results/2017/20170505/EachResult01.pdf
