I had another attempt at converting my wheels to tubeless at the weekend and it appears to have worked, but I am worried about the long term durability/reliability of it.
I did it like this:
- Removed the blue Spesh rim tape from the wheels (DT420SL rims), cleaned the rim & replaced with electrical tape (red, as it's faster). I ran it around one side as close to the edge as possible and then the other side to try & seal the spoke holes.
- I then used ptfe tape around the base of the removable valve and secured this in place.
- I put the tyres on, inflated and stuck them in the bath to check for leaks. There appeared to be none on the front tyre & a hole on the rear tyre from a thorn at the Enduro6 but otherwise no air was escaping.
- I stuck the sealant in and re-inflated the tyres, sloshed the sealant around and stuck them back in the bath. Both tyres were now leak free.
I checked them regularly and they didn't appear to be going down so yesterday I did 25 miles on them and they help up fine.
But - is the electrical tape likely to hold over time? I'm taking the bike to Spain in under a fortnight and don't want to find that they stop holding air a few days in? Or am I being paranoid?? I don't really want to take a load of electrical tape & sealant with me to re-do them, if I can help it.
Your thoughts/experiences would be appreciated.
