I don’t mind riding in the rain as once you are wet, you cannot get any wetter so when I reached the 18km mark I was soaked as the rain started bucketing down from 14km onwards. At 18km my back wheel went in a controlled slide on the wet hot mix bitumen track. Uh oh! I thought better slow down. Next corner felt the rim bump on the track. A bloody flat tyre, great! Stopped and pumped furiously, climbed back on and turned around for home. Only had to pump it another 16 times before I got to a half a kilometre from home and the tube wouldn’t retain air anymore. Walked home and got cleaned up. I spent 1/2 hour trying to get old tubeless tyre off and eventually I broke the seal. Shouldn’t have been so hard as had previously removed tyre to fit a tube as plugs would not seal the previous penetration. Spent another 40 minutes putting a new Schwalbe G1 on which was easy but getting a seal with my low volume 4WD compressor was a challenge. Finally got a seal, put valve in and pumped up with floor pump to hear a satisfying pop or three as the tyre seated properly. Pulled valve out and put in 70ml of Stan’s tyre sealant and pumped with floor pump to 50psi pressure. Wiggled wheel all around to distribute sealant over tyre bead and put wheel back on bike. An hour later still holding pressure. Fingers crossed , all good! Distance travelled on old tyre was 3,268km. Piss poor mileage. I had planned to change the tyre early next week too.
