I removed the gubbins from the saddle bag. I removed the light from the handlebars. I turned the bike upside down. I loosened the brakes. I took the wheel out. I applied tyre lever No.1. I then attempted to get in tyre lever No. 2. Try as I might (and there were a LOT of tries), I could not get the second lever in anywhere other than next to No.1. And when I tried to move it along, to loosen the tyre from the rim, it was absolutely jammed solid. My combined hand / arm strength was no match for this tyre. After 10 minutes of rapidly improving swearwords, I had to admit defeat, walk to the station, get the train and walk home.
Late for supper
Late for my longed-for glass of wine
And with a huge dent in my pride.
This weekend the boyf shall be removing the old tyres and I shall be applying new ones, ones that I am able to actually remove / apply myself.
EDIT : The boyf (who normally only uses his hands to remove / replace tyres) had to resort to tyre levers to get the tyres off. And he broke a lever in the process. Clearly those are stubborn tyres. I feel slightly less useless as a consequence.
