Just want to tell that yesterday while riding - not paying attention enough -and I happened to ride through a lot of glass splinters and remains. Someone had smashed one or two beer bottles on the cycling track. I happened to drive right through and over a lump of glass that "snapped" loudly which alarmed me.
I stopped and found out that no damage was done!
I kicked the glass rubble aside and continued my tour. Anyway, today the tires are still OK!
Thumbs up for Bontrager!
