Hi there wisemen,
I use a Brompton in Helsinki for every day commuting. Brompton is in use also in autumn & winter, which means that conditions are often quite rough. I've had the bike now for 2 years and I've driven it ~7000 km.
Now I found out that rear rim is almost worn out. The "groove" in the middle of the braking surface has totally vanished. Questions are:
1. Has the wearing been abnormally fast?
2. I've used koolstop grey pads. Are there some better pads available that do not wear the rim that fast?
3. How soon will the rim collapse (and how badly will I hurt myself when it happens)?
Thanks already for distributing knowledge.
