Yea, I use cloth tape and so it gets replaced now and then. I just did my Mondia and wiped them down with brake cleaner to get the goo off. After 50 years, the 3ttt bars were still pretty good. I think some bars are anodized to start with and that helps. I have ridden the heck out of this bike, never in the rain and I don’t have sweaty hands. Still good to check. I never even thought about stuff like that until I saw a couple of threads on this forum of stuff like this, it happens. Better to catch it before it actually fails, that would ruin a ride! Better to have a bad day on the stand than a bad day on a ride.
