Hard to let one go, after all those miles!
I'm a Bobcat, Mr Zimmerman fan, who uttered 'he not busy being born is busy dying' - not sure that he cares about bikes, but the spirit is maybe 'get a new one, don't regret the old one'
I'm currently thinking the same about letting go the tandem (Santana Visa) on which I had many enjoyable miles with the little'uns - and getting a new better one after 20 years
But hard to let go
