The recumbent has had a bump in the rear tyre for weeks. I've been lazy to do anything about it, and also interested in finding out how it will perform.
Today, I found out. Fortunately I hadn't managed to get even a kilometre from home, before the telltale feeling of running on a totally empty tube. I stopped to inspect the situation. The tyre had a slash about three centimetres long, multiple millimetres wide. Jury-rigging damage like that would be nasty even in the middle of nowhere, so I decided to walk back and pick another bike to get to the office at a sensible time.
Now I need to decide whether to put a Stelvio on or to decide it's winter and put the Innovas on. Last year the first spill because of ice was on the first of November. It is unseasonally warm now, but if the wind turns, it will change rapidly.
The Stelvio naysayers got it wrong. The rear tyre which broke was a City Marathon. The front which is a Stelvio has almost as much distance (around 2000 km) as the rear. The Stelvio is unblemished.
The place to get Schwalbe tubes and tyres in obscure sizes in Helsinki is Velotrade at Roihuvuorentie 30. Well, at least if you are not trying to find a 451. In that case you are out of luck anyway.
