The Shard...

It's done none too bad. There's been one pinch puncture in about 4 months but this morning the Crammond Foreshore proved once again who's boss by dealing me a puncture through my Marathon Plus tyre. This mussel shell shard managed to get through the centimetre or so of extra rubber under the running surface of the tyre which gives it it's puncture protection.

That is a framer, it's almost bigger than my thumbnail.
