Just saw my neurosurgeon today. He was fine with cycling but I'm gonna tell my wife he said I needed an endurance bike !!
He actually said that it wouldn't hurt all the metal he so painstakingly screwed into my neck but it would probably be painful.......he's right but I've always been really good at suffering through things. I get some pains down my arm for a few hours after a long ride but that's part of it. He said as long as any symptoms are transient I can keep it up.
Gonna try that 100K ride hopefully on the weekend after this one.
And am serious about an endurance bike...I think that would take alot of strain off my neck.
