I heard this strange sound when I used the cap on my velomobile. I heard it since a few months, but didn’t care. With the cap though, it was so loud that it became a nuisance. So yesterday I dismantled the wheel and found the poor condition as you can see on the photo …

It’s the condition after 38.000 kilometers without any maintenance , except for a few drups of oil every now and then.

Will it hold till Spring 2012 ???

NB: the Marathon Plus tires will be renewed soon, because they’ve done 8000 km. and the blue anti-flat layer is not a perfect “contact-surface”.
