If you have read my recent post on the London to Gravesend trip, you will know that I suffered a rear wheel puncture. When the wheel was off the inner tube has a hole in it. I actually had the same problem earlier in the week and had changed the tube for a new one. Unfortunately after a quick trip to the shops on Monday I discovered another slow puncture.
Examining the tube I discovered another small hole that looked like the other two. I then started to examine the tyre and all I could see was a small raised piece of rubber the size of a pin head. Rubbing a finger over it appeared rather sharp and I strongly suspect it was this that has caused the punctures.
I tried my best to smooth things but had no luck and resorted to buying a new rear tyre. It arrived this morning and I wasted little time fitting it - and another new tube. I hope that this solves the problem. I opted for another standard Schwalbe Marathon which is my favourite commuting and general purpose tyre. Many like the Plus version but I disliked them a great deal.
On Saturday I have another Evans Cycles Sportive which I am looking forward to greatly. Let's hope I have a clear run now that I have a spankingly new tyre on!
