Brought a used giant defy of
ebay for £250. - I can put mudguards and any array of lights racks and things - that I just wouldn't want to do to my best bike. I would expect things to wear out quicker on this bike - partly because of the weather - and partly because of the nature of commuting, lots of braking, clicking in and out.
I could ride to work on my best bike - but feel a used cheaper bike is a more appropriate tool for the job.
I wouldn't wrap a best bike in cotton wool though - they are meant to ridden.
Expecting things to wear out more when they are used more is fairly logical though?
I understand the idea of having a 'best' that you keep clean and so on. I have a suit in my wardrobe - it comes out for funerals these days. I wouldn't do the gardening in it - and I suppose the reason is that it wouldn't fulfil a key part of it's function if I did. My suit has a few jobs:
1) to cover the parts of me that are societally unacceptable to expose in public
2) to provide a degree of warmth
3) to 'look smart' and indicate externally that I respect the occasion I am attending
If I also wore it for gardening, it would most likely not fulfil criteria 3, so I wear old jeans and jumpers in the garden - knackered old clothes with tears and stains from DIY and gardening.
I guess for some, their bike has roles akin to a suit - it's important to them that it looks 'right' either to send a message to others, or for their own benefit. I suppose part of wearing a suit is also to make you feel like you fit in?
To others, their bike is like my gardening clothes - it' already less than perfect, so just use it until it's beyond useful or repair.
And for yet others - and I include myself in this - the bike is 'smart casual' - not precious, not pristine, but functional in most circumstances.
