For me Sheldon was one of the many gurus that are there when you need them.
I never had any personal dealings with him apart from CR correspondence but
his knowledge was there as a backup and gave me a confidence that whatever
problem or mystery was encountered Sheldon would likely have the goodwill,
knowledge and experience to overcome it. A pillar of the cycling community.
His passing is a shock and a great loss.
Condolences from this side of the pond.
