• Wonder when every one says make sure no bubbles under the tape how far do you take it?

    Spent yesterday around 2-3 hours to do, for the first time, a tubeless setup. Damn is a work for the patiencent ones. I was really wondering if is such a good thing and if this setup is such a fesable thing. Time will tell!

    So, my experience.
    Tesa tape, not very strechy. Had to put quite some tension to keep it flat with the rim. Then, when you go with your fingers over it only a small portion properly sticks to the rim imediatly.

    After each streched section and finger pressing, done this with the blunt end of a skewer:

    • lateral movement, perpendicular to the middle channel walls to sit the tape;
    • pressing along the middle channel to sit the tape closer to the wall edge and on the wall.

    The overlaping part of the tape is trickier as bubbles don't have where to escape compared with the 1st layer which can go into the spoke holes.

    After I have done the middle channel poceeded to firmly stick the tape on each side of middle channel up to the rim wall.

    I might have take it to another level and must discover an easier way. The good thing of it, I guess, is that the setup worked from the first go and have not experienced any leakage once the tyre was beded with the help of the 2L coke bottle.

    Eager to see how this set up will behave over time.

    When I apply the tape. If you start with no bubbles, your job on that front is done. To ensure a good bond before exposing the tape to service conditions, I press down on it with a sheet of rubber and a pressure of about 500kPa. It's easiest to do this if you form the rubber sheet into a torus and constrain the part not pushing on the tape with a fabric bag.

  • Can you show me a picture/video with the rubber torus, please?

    My aim was the same, to avoid any bubbles from begining. But, as the tape sits, even with the tumb pressure[not sure if mine is a cobbler's:))] it only properly sticks bubble free on the rim for a width of 6-8mm. Than my tumb cannot properly press agains the joint between the middle channel and its walls so about 2mm are left "loose" untill something smaller is used to fit those areas and push the air out.

  • This is amusing.
