After a long time deliberating , bit the bullet and fitted the OUTEX tubeless conversion kit to my spoke wheels. Easy and worked well (well they haven't lost any pressure after 5 days), thought I'd just post up a positive recommendation. The only thing I had to do extra to the instructions was treat a fair bit of rust (chrome steel rims) that had developed under the rim tape. Obviously water entering through the spoke holes. OUTEX has a video where they just grind the rust away and install the tape over it. I made the decision right or wrong, to treat and seal the rust first (sandblast, chemically clean, and 2 coats of two-part marine grade epoxy primer). Treated the whole 'well' between the bead shoulders. In the process made sure the nipples had a good seal of paint as extra leak protection. Anyhow, for what its worth, seems a good easy to apply product that worked as advertised. P.S. Why get rid of the tubes?? Every day ride was a gamble that I didn't get a flat. Extended trips required extra gear to remove wheels, and weight of a spare tube in the bag. Plus got rid of 3/4 Kilo of un-sprung weight out of each wheel.
