I think it’s just several jobs coming along at the same time, I have times like this when several bike all need work concurrently.
thats the curse of N+1. A fault/ flat / worn part can either be solved by prompt necessary maintenance, or just by putting it to one side deciding to ride another bike. Until that also develops a fault/flat/worn part. Then you decide its time to ‘rediscover’ the single speed pub/spare parts bike and a purer kind of riding, until thats on the wonk as well.
Eventually you have a shed full of bikes – its the middle of summer – but nothing you can actually ride. Faced with a mountain of maintenance you start shopping for parts, aware that all your forthcoming riding time is actually going to be tinkering time – and as you do you start mulling over the notion of ‘the ultimate do it all bike’ that somehow fills all the niches between all the bikes currently in the shed (it couldn’t course be a ‘do it all bike’ that replaces all the bikes in the shed) and more importantly, works. At least currently.
