Root cause analysis of this evening's incident properly belongs in this thread's counterpart, but my tale of woe may be recounted here; to wit, cycling home I'd done a couple of miles and reached Myreside Road, and for the heck of it and because I'd managed to leave work a bit earlier today I wasn't in a rush, I diverted to ride through the Royal Ed.
The super smooth path soon revealed a regular but gently bump-bump-bump coming from the back of my bike. This was quickly joined by scuf-scuf-scuf. Thinking I'd ridden over a nail that was now impaled in my tyre and rubbing on my mudguard I stopped and inspected. No nail, just a huuuuuge bulge in the tread, like half a hazelnut around but as tall as my finger is thick. I realised that the main part of the bulge wasn't tyre but inner tube. As I thought, "she's gonna blow!" and "I'd better let some air out of the tyre", it went BANG!.
And I wasn't carrying a pump, a tube, a tyre boot, or my repair kit.
Fortunately Bike Morningside was but a relatively short and, on the face of it, really quite pleasant walk away. New tyre, new tube, and he let* me just do the work there and then with the shop tools.
