I just installed a rimlock for the first time and was surprised at how much work it added to replacing the tire. Maybe the next one won’t be so much trouble but this one bit me at every turn. First the edge of the tire pulled the rubber band over the rimlock, then I had to jimmy the edge over the tire and push it up into the tire to get the get the bead past the rimlock, then it was fighting the tube air nipple into the rim without interfering with the rimlock, then I filled the tube several times to work out the kinks and finally got the bead set. Bead lube plays hell with talcum powder! That was not fun. BTW, how tight is the rimlock nut supposed to be? a utube vid suggested two (1/8) turns after firm but what is firm?
