The Tubeless Compatible System (TCS) requires certain parts/applications not found in a tradition wheel set up. In order to utilize the Tubeless aspect of the system you will need the following Components along with a TCS Rim and TCS Tire.

TCS Explained - Info Flyer
What is TCS?
ALN: (Tubeless Compatible System) wheels, rims and tires provide sealant tubeless with complete compatibility to international standards.
Can I put any tire on a TCS rim and run it tubeless?
ALN: No. You can however install and run any conventional (non-TCS) tire & tube combo on the TCS rim. In order for it to be tubeless you must mate the TCS rim & TCS tire along with the special tape, valve & fluid.
Can I put my TCS tire on any rim and run it tubeless?
ALN: No, but the TCS tire will fit any conventional (non-TCS) rim. If installed onto a conventional (non-TCS) rim you must utilize a tube. In order for it to be tubeless you must mate the TCS rim & TCS tire along with the special tape, valve & fluid.
What’s so special about a TCS tire compared to a regular cheaper tire?
ALN: Actually there several different key factors. Without giving the recipe to the competition we can say it’s all in the bead. The TCS tires also utilize SPS (Sidewall Protection System). It’s a nylon breaker… which helps air retention. Tires are porous so air naturally bleeds through.
What’s so special about a TCS rim compared to a regular cheaper rim?
ALN: The primary difference is the tire-well shape (internal-well). It’s a unique shape that features superior tire retention capabilities.
What if the tire is gashed?
ALN: If the wheel is set-up under tubeless with fluid installed the fluid will seal upwards of ¼”. Beyond that you’re SOL.
Why has it taken so long to come out?
ALN: Great question. The rims are fully functional and already being sold. We’re in process of designing even more TCS rims. The issue was the tires. We were having issues with bead stretch and high PSI. We’ve since design & outsourced a special bead and we’ve changed tire suppliers.
What is the difference between the TCS Malice and TCS Felon?
ALN: The TCS Malice is a narrow light weight race rim whereas the TCS Felon is a much wider street rim.
What is the difference between my old Felon rim VS. a TCS Felon rim?
ALN: Overall exterior shape is the same. The internal tire-well on the TCS Felon incorporates the enhanced design. In addition we’re 4D center drilling the TCS Felon to eliminate any potential spoke pull. In the past the Felon was drilled with an offset pattern.
Can I run a regular tube in the TCS Malice or TCS Felon?
ALN: Yes; of course. On the newest stock will have two valve holes. The special TCS valve and a SV. This way you do not need to drill out the TCS valve to install a SV. If you’ve drilled out the TCS valve you cannot retro fit the rim to be tubeless.
How much more would this be than a regular wheel set up?
ALN: The TCS rim & TCS tire will cost as much as any conventional product. The tape and valve will run approximately the same price as a tube and strip plus $10. The additional cost is the fluid so overall you’re looking at an additional USD$25.00 +/- $5. Keep in mind for that extra money you’ll have extra tape & fluid for additional set-ups down the road.
How much weight can I save?
ALN: This is subjective. Without knowing what your current set-up is it’s hard to say. On average we believe ½” pound for the set. In some cases more and some less. Again it depends on what you’re set-up is now.
What do I need to buy to have the whole wheel ready for TCS?
ALN: TCS rim & tire, tape, valve and fluid.
Can I use a regular rim strip and run TCS?
ALN: No. You must use the tape to create an air tight seal.
I’ve had TCS in my mountain bike, what is the difference?
ALN: The concept is the same overall we’ve just standardized the platform. The rim design along with the tire beads are the real difference.
Is the sealant the same as the green slime stuff?
ALN: No. Ghostbusters called and they want that shit back. Our fluid is a concoction of liquid latex with extremely fine particles. It layers and coats all the micro holes in the tires. It seeks out any source that might leak and seals it.
Tubeless is known for “burping”, will this still be a problem, and how have you fixed it?
ALN: It shouldn’t be an issue at all with TCS. The bead lock system developed provides superior fit and retention.
Looks hard to put that tire on, why can’t I use a tool to put the tire on?
ALN: The production models being released install by hand & uninstall by hand. The key is to guide the tire beads into the center channel within the tire-well.
Why a presta valve?
ALN: Because this is the industry standard for tubeless. As time progresses we’ll investigate opening the tooling for a SV. With the removable core you can get significant air flow into the tire so theoretically a SV is not needed.
Does the tire need to be at a certain PSI for TCS to work? Or can I run a lower PSI or higher PSI to my liking and preference?
ALN: 45 to 85 PSI is the designated PSI per the tire sidewall markings; however, upwards of 110 PSI should be achievable. We are still testing the extremely high PSIs so the jury is out. More soon…
Can I use a hand pump or must I use a compressor?
ALN: All that is need is a common air pump when setting up tubeless.
Are there going to be more tire options?
ALN: Yes. For race we’ll have a 1.75 R1, 1.85 F1. Then a whole series of 24” race tires. For street a 2.1 138.
Does the fluid need to be changed?
ALN: Not necessarily changed. Over time it will breakdown (dried up or evaporate). With the removable core it’s easy to insert another oz or two without removing the tire or wheel from the bike.
Will I need to constantly be adding air to my tires every time I take my bike out? Meaning will these tires leak more air than the standard bike while sitting over night for instance?
ALN: No. In reality the TCS set-up with fluid holds air longer than a conventional tire tube combo. If you have to add air frequently check the valve. It may not be secured at the rim & or the core is loose.
What if other companies come out with TCS?
ALN: First off; TCS is TM (trade-marked). I caution anyone to be extremely skeptical if someone uses the words “BMX tubeless”. The technology we have developed will be the standard for everyone to follow. A great deal of work has gone into creating the standards & dimensions required for the system to work.
Would the TCS be something like the pivotal, where a lot of companies can make something that are compatible with each other?
ALN: Yes! We are now in discussions with other BMX brand to license the technology. The more brands the better so consumers have choices.
What is 4D drilling?
ALN: This is a new drill process found on the TCS rims. Creates a prefect interface between spoke & rim. This exact angle reduces binding and the need for eyelets.
Alienation's New Tubeless Tire System Part 1
Alienation's New Tubeless Tire System Part 2
Tools Required: All, Needle Nose Pillars, Scissors, Wipes (towels)… optional BBQ wood skewer
- Loosen valve core prior to installation to hand tight (will remove later so it makes it easier)
- Clean the tire well with rubbing alcohol so tape adheres to the rim surface
- Cut tape on 40 degree angle
- Preinstall the Velo plug. Get it as flush to the tire well prior to taping
- Tape entire rim twice
- Check tape on sidewalls within tire-well to be flush. Press bubbles out through open tape end. Do not cut / trim the tape in any way.
- Put dimple in tape at the valve by coming in from the spoke-face side of rim
- Turn clockwise as you press All through the tape
- Close the core tight so it doesn’t bend to break as you push it through the tape
- Tighten the valve on the opposite side of the yellow decal
- Cinch the valve till tight to the rim
- Install the tire from right to left and left to right
- Once tire is fully installed press down in the center pushing the beads outward creating a tight seal
- Rotate tire while pump to help seal
- Make sure the valve isn’t exposed so air flows into tire (when tire is seated to rim prior to inflation)
- Remove the valve core so you get more air flow into tire bladder
- Preinstall the tire to rim at 40 to 50 PSI. Check the tire is seats on both sides 360 degrees. Safety line should be equal.
- Press fluid hose onto valve first then insert to bottle
- Use some extra fluid around the bead to help seal tire to rim
- Bounce the wheel once seated to get the fluid mixed around so it can seal up an open pore
