To be fair to
@jamma I have now retired my summer bike until the spring. The gritters have been out in force round here and I won't use my summer bike now until probably March at the earliest, I am ideally looking for some periods of heavy rain followed by sun, to wash away all the salt. It has carbon rims so I'd rather not get the braking track too grimy / wear them more than I need to. The winter bikes have discs.
That now just leaves me with my winter bike and my wet weather bit to choose from for the next few months. There are almost too many bikes to choose from, so I have to have different ones for different occasions.
It will be even worse next year when the new stead arrives, I think that the current summer bike will be come my Sunday club ride bike and the new one will be short and fast / chain gang.
I never thought I'd say it, but once the next bike arrived I will have the correct number and won't need anymore (for a while). It would appear that the correct number of bikes for me to own is not N+1, but 7. A sad day indeed, feeling you have enough bikes...
