Solid tryes

Lets pretend that these are low rolling restistance tryres
could you fit them to a C5 ?

Assuming you can get them onto the C5's plastic wheels without causing any damage to either the wheel or the tyre, then I can't see any reason why these won't work. They certainly appeal to the "green" side of me 

I guess those exploding inner tubes are still giving you nightmares then  ?

This would mean that we've gone full cirle, my first bike when i was a kid had solid tyres

The company offer a free fitting service, and have been told you can get LRR tyres.  I was wondering if anyone had any experience and wondered if the plastic wheel could take it.  Might be a idea for a future experiment.

I like your thinking, something to add to the list - once I've completed my present project
