Tubeless kit for 2 road wheels

With 2 detechable presta valves, 2 rim strips, filament adhesive tape, 500ml bottle of sealant, valve core remover, schrader valve adapter, sealer syringe doses and instructions.


NB: Road rims are the same diameter as the 29" MTB. This means that the road bike kit is similar to the 29" MTB kits but for a narrow rim bed (16mm wide). For this reason any road rim with a 20mm wide rim bed can use a MTB 29" (20mm rim bed width) tubeless kit to be made tubeless-ready. In the case of wider rims, a 29" tubeless kit for a 23mm rim bed width can be used.  


Step 1. Preparation of the rim: Remove any rim strip or tape previously on the rim and clean the rim thoroughly. To do this you should use a rag with a household dissolvent that is not alcohol, white spirit or other cleaners. Remove all traces of dirt left on the inside of the rim. If the rim is carbon, use alcohol only in this case, which is milder. Leaving any dirt on the rim will cause tape adhesion issues. Check the rim for any cuts or sharp edges and use sand paper to sand any rough edges in order to avoid future cuts in the rim strip.

Step 2. Taping the rim: a) to cover the spoke holes use the filaments adhesive tape applying 2 full rounds of tape, starting anywhere on the rim, slowly and carefully to avoid twisting it and making sure it is well centered. As the tape is transparent, you will be able to see when the second round is applied. b) use the yellow plastic rim tape provided in the kit to cover the transparent adhesive tape. Please note that it has a rough side and a smooth side. Place the rough side down so this side is in contact with the transparent adhesive tape and the smooth side is on the outside. Start taping the yellow rim strip, starting at the valve hole. At this point reinsert the valve as this will help keep the yellow rim strip in place when seating the bead to the rim.  The yellow rim tape sits very tightly so apply slowly and carefully assuring it is well centred using a screwdriver to help align and centre if needed.  If rim strip is very tight, use two screwdrivers as levers to ensure it stretches and sits on the adhesive tape correctly. If in some areas the rim strip is not well centered, use a screwdriver to lift the strip and centre correctly.

Step 3. Mounting the Valve. Insert the valve in the valve hole. If both transparent adhesive tape and yellow rim strip have been installed correctly, the valve hole should be open except for the transparent adhesive tape. Puncture the transparent adhesive tape, being careful not to enlarge the hole, and insert valve. Tighten the valve nut gently, do not use tools as the value nut is made of aluminum meaning it is delicate and can be damaged. Tightening it by hand is sufficient. We recommend putting a drop of lubricant oil on the valve nut to ensure easy future removal.  Normally you will use the flat gasket provided (D) but in the case the valve hole is big you can use a conical gasket (C). The kit comes with an adaptor (A) in order to inflate with a compressor and with a small black tool (B) to assemble and disassemble the valve cores.

Step 4. Sealant liquid. The sealant liquid comes prepared to be injected directly into the tire, always shaking well before using. The recommended dose per tire is 30 – 40 ml. A little more liquid can always be added so long as the total dose is no more than 50mls otherwise the tire can become unbalanced. SHAKE WELL BEFORE USE.

Step 5 Mounting the tires.  Have a set of tire levers handy. Spray the sides of the tire and the rim bed with clean water. It helps to wet both the tire and the yellow plastic strip with water so that the tire slides, with little resistance, along the yellow plastic rim strip as it is being inflated avoiding any displacement, wrinkling or even partially removing of the yellow rim strip. Once the tire is mounted but before seating the final inches of the bead into the rim, leave the smallest opening possible (the size of this opening will depend on your tires and how easily or not the bead enters the rim) then carefully inject the sealant liquid.  This is a tricky part of the process therefore needs to be done slowly and carefully ensuring the sealant liquid doesn’t spill out of the tire. Fill the tire with the recommended dose. Once filled, quickly but carefully, finish seating the bead into the rim. Check to make sure that the tire is properly seated in the rim and in the valve area.  The second option is to finish mounting the tire onto the rim then loosen the valve core and inject the liquid through the valve into the tire.  If you do this, you need to ensure you clean the valve core and valve cavity very well otherwise the liquid, which is a sealant, will stick to the insides of the valve making it difficult to remove in the future.  We  recommend using a compressor to inflate your tires.

Step 6. You can now inflate your tires with a pump or compressor (recommended). Again, we recommended spraying the joint between the tires and rim with water which will make inflating a lot easier and avoid any displacement of the yellow rim strip.  If using a compressor, protect your eyes as when applying air pressure, some sealant liquid may spray out given the pressure exerted by the compressor. Once inflated, check the gasket of the valve. Rotate and shake the wheel in all directions to ensure the liquid is well spread out inside the tire.  We recommend not to release any air pressure once inflated and to leave the tire for a few hours to let the liquid settle inside. Check the air pressure the next day and adjust according to the cyclist’s preference. We recommend riding the bike after mounting and inflating to seat the tires on the rims and allow the liquid to spread inside the tire to all the pores assuring an effective sealant process. When mounting the tire for the first time we recommend checking it frequently during the initial hours and moving it to ensure the liquid inside fills all the micropores inside the tire completely. If the tire loses some pressure during these first hours it is normal, inflate some more, rotate and shake the wheel to ensure the sealant liquid is covering all the inside pores. If the tire deflates in a matter of seconds, this is not normal. Check the rim bed ensuring it is well covered and the valve for any possible leakage.
Step 7. Periodic refill of sealant liquid: It is difficult to calculate how long the liquid will last in your tires as this depends on a number of factors: how porous tires are, climate conditions and outdoor temperatures, proper or improper sealing of tires, etc.  We advise you to check your tires at least once a week and if necessary, remove the wheel, shaking it to see if there is still liquid inside. You will be able to lower the frequency of these checks after the initial mounting and sealing process has been deemed effective as the micropores are filled with the sealant liquid. If the tire starts to lose air pressure continually, you will need to refill it with more sealant liquid. There are two ways to refill your tires: one is to partially deflate the tire, insert a tire lever just enough to create a space to insert the neck of the sealant bottle and refill. The second option is to loosen the valve core and inject the liquid through the valve into the tire.  If you do this, you need to ensure you clean the valve core and valve cavity very well otherwise the liquid, which is a sealant, will stick to the insides of the valve and valve core, making it difficult to remove in the future. (valve cores are sold separately).  We recommend that you refill your tires at least every two months; it may be that the tire has not lost pressure, but the sealant liquid does suffer some deterioration over time therefore needs topping up.

GENERAL REQUIREMENTS AND RECOMMENDATIONS: The X-SAUCE Road Kit should only be used with tubeless tires. Tires: should be double walled. Air pressure:  use the air pressure recommended by the tubeless road tire manufacturer. Never compare or equate air pressures of inner tubes + tires with air pressures for tubeless tire systems. A tubed tire can withstand 8.5 - 9.5kgs of pressure without a problem and is actually preferred to avoid pinching it with the rim, however tubeless tires will take about 7kgs of air pressure and still be harder than a tubed tire at the same pressure level.  This is a common error that riders make thinking that tubed tires and tubeless tires should be inflated to the same capacity. In fact, if you inflate a tubeless tire with the same air pressure used in a tubed tire, you run the risk of rupturing the tire due to unseating or excess pressure.  NEVER exceed the pressure recommended by the manufacturer. Tips for inflating tubeless tires: mount the tire spraying both the tire and the rim bed.  Damping both parts with clean water will make inflating easier and will also prolong the life of the rim strip (inflating a dry tire and rim strip increases the possibility of wrinkling or displacing the rim strip). 

IMPORTANT:  If the tire does not inflate easily, remove the valve core and inflate without it. In this case, be careful, as the pressure will enter at a faster rate, making inflating the tire a lot easier but once the tire is inflated and seated in the rim stop inflating otherwise there is risk of rupturing the tire due to excess pressure. Remove the compressor, use your finger or thumb to stop the air from flowing out of the valve then quickly replace the valve core, screwing it firmly into place, minimizing the leakage of air from the valve.  If some pressure has been lost while replacing the valve core, you can easily top it up at this point to the required level. Use protective glasses while inflating tires to avoid the possible risk of small sprays of sealant liquid escaping due to air pressure during this process.  Check your tires regularly especially after mounting them for the first time.  If you observe that some liquid has dried up inside the tires, refill them as soon as possible.  These periodic and regular checks ensure a longer life and better functioning of your tubeless tires. If in doubt of the amount of liquid left in the tires, add half of a normal refill dose.  Any excess liquid in this case is not an issue and only adds a few grams of weight to your tires.  Use only rims and tires in good condition.  Do not mount tires that are worn, old or have cuts, scrapes or defects that compromise the integrity of the tire and potentially causing an accident. Remember to use only tubeless tires. If the valve becomes obstructed with sealant liquid, you can take it apart and clean it. Use the black tool included in the kit to loosen the valve core.  Clean the inside of the valve and the valve core carefully avoiding use of any sharp objects which can damage sealing or adjustment parts (gaskets, threads, etc.) of the valve.  A tip for keeping the valves clean is, after rides, to leave the bike with the valves positioned at the bottom of the wheel, or as close as possible to the ground. This way any sealant that may have seeped out does not stay in the valve but drains back into the tire instead.  REMINDER: Check liquid levels in your wheels periodically and regularly. Do not let the liquid dry up inside the tires as this will cause pressure leaks and punctures on route that will not be able to auto repair themselves.  Always use tubeless tires. We recommend refilling your tires with the recommended refill dose at least every two months; even though the tire has not had any air loss, the liquid inside looses some of its properties over time and needs to be replenished.
