I hit a ridiculously huge pothole hidden in a flooded Devon lane on Friday and got an instant front wheel puncture. That is 2 years on the trot that I have made the mistake of thinking that riding slowly through a brown swamp makes it safe. Not when the holes are 15 cm deep and have sharp edges!
I flagged down all the drivers approaching while I was putting my spare tube in. Some diverted when I told them how deep the holes on both sides of the road were. Others thanked me and drove through very slowly. Even so, the vehicles were juddering and clunking. One local said that he witnessed another driver try to go through at full speed that morning and wreck a front wheel! Apparently, the road has been like that for weeks due to a blocked drain.
A young female cyclist came along and I warned her that there was only a very narrow strip of tarmac in the centre of the road, with big holes either side. She aimed for the middle but did exactly what I'd done - slipped off into the depths, came to a dead stop, and toppled sideways. At least she didn't get a flat tyre and she wasn't hurt.
Anyway... fettling! When I got back I repaired the original tube. It had a vicious snakebite puncture. I wasn't happy with how long the 'bites' were but gave the repair a go anyway. I let the glue dry and then swapped the repaired tube back onto the wheel. I wanted to be sure that the repair would hold, rather than keeping the tube as a spare and discovering later that it didn't. And, sure enough, it did
NOT hold! The tyre went flat very quickly. The patch had been stuck down adequately but one of the 'bites' had continued to rip open under pressure and had torn the patch too. Not worth messing about further, so the tube was scrapped after only 6 hours of use. I ordered 2 more spares which came today!
I have switched over to 32C tyres for my Devon bike. I had been running them at 4.5 bar F and 5.0 bar R for comfort but have now gone up to 5.2 bar F and 5.5 bar R for a bit more protection. The tyres are still pretty comfy and roll better. I may even add another 0.2-0.3 bar for tomorrow's ride to see how I get on.
More fettling... The bike has been making ticking noises which annoyed me. I decided that the cassette lock ring probably needed tightening. I also wanted to check and clean the cassette so I ordered a chain whip and cassette tool yesterday on overnight delivery which arrived this afternoon. I took the rear wheel into the garden and sorted it out in the sunshine. The cassette was filthy so I scrubbed that. The freehub too. I greased everywhere that looked like it needed it and put it all back together. The bike is now tick-free!
I also adjusted the rear derailleur and endstops. The 11-speed bike had become a 10-speed but has now regained its missing gear! The indexing is now spot on too.
