Go Tubeless Ghetto Tubeless
An easy mod to lighten up those wheels, free up some rotational mass. All with out sacrificing any reliability and also no more worries of pinch flats. You will also be able to run lower tire pressures for better traction. In Sedona this is the set up that almost every rider I ride with uses. Most of us use Maxxis 2ply tires usually Minions or Marzzochi tires..........Did I mention it will cost way less than any other tubless set up.
• Tire preferably one with a smooth bead (kenda tires do not work well) UST work well but actually so do most non UST as long as the bead is fairly smooth.
• 20” tube preferably with fully threaded schrader valve stem. (yes 20”)
• Fiber tape.
• Electrical tape.
• Stan’s solution (sealant)
When cutting the edge, make sure to leave 2 or 3 mm for safety.
• Utility knife
• Wheel Stand
• Air Compressor
• Valve removal tool
• Allen wrenches to remove wheel
• Spray Bottle with soapy water
1. Remove wheel from bike
2. Remove tire & tube from wheel.
3. Remove rim strip.
4. Clean inside of rim thoroughly.
5. Take fiber tape and make at least two wraps around the inside of the rim each wrap offset from the other for good coverage, making sure to cover all holes inside the rim. We will later cut out the hole for the valve stem. This will replace the rim strip.
6. Now make at least two wraps with the electrical tape on top of the fiber tape, again offset for good coverage.
7. Find the valve stem hole and cut a hole through the tape.
8. Take the 20” tube inflate it slightly to give it structure. Now stretch the tube over the rim inserting the valve through the rim.
9. With the tube now appearing as a slick tire on the wheel take the scissors and cut the tube down the middle all the way around. When done you will have a flap hanging over either side of the rim.
10. Clean off the powder inside the tube.
11. Generously coat the tube with soapy water and mount the tire on the rim over the tube, making sure the flap of tube is still hanging over the rim and to not cut the tube in the process.
12. Now remove the valve core and take the air hose and fill up the tire with air to seat the bead. The tire should inflate and hold air bubbling lightly from the bead. (Intense 4ply tires require extremely high pressure to seat the bead, I was unsuccessful with my local bike shops compressor had to use tire shops compressor.)
13. Take the Stan’s solution and fill the tire according to directions from Stan’s. (2oz for 2.35 and smaller 4oz for 2.5 and larger)
14. Reinstall the valve core and fill tire with 35psi. Spin & shake tire to distribute Stan’s solution.
15. Tire should not leak or continue to spin and leaks should disappear.
16. Flap of 20” tube should be uniformly sticking out of tire bead seam. Place wheel on stand and carefully trim the flap at the bead edge, careful to not cut your tire.
17. Reinstall your wheel and set your tire pressure.
