I grew up (and rode and raced) in the same area where Jobst rides; it was a hotbed for great cyclists back in the 70's and 80's. Jobst did epic long rides, and was very strong, leading some very accomplished racers (of the time) like Keith Vierra and Marc Brandt. He was, and apparently remains, extremely un-approachable, grumpy, and phenomenally insecure. He is a pompous, insufferable man who's contribution to cyclng is that he wrote a brilliant and thorough book about how wheels used to be built. End of story.
In complete contrast, there is a wonderful human who found me, 36 years ago, riding (in tennis shoes) along Alpine road on a horribly insufficient Peugeot that had become much too small for my 13 year-old-body. Rather than speed by, with his nose in the air, He paced me home, found an extra-long seatpost for my bike, took me to get cycling shoes fitted and cleated, and encouraged me on multiple training rides. Years later, I found out he did this for tons of people, jumpstarting their lifelong passions for racing as well. Unlike Jobst, he actually had the guts to put it out there, and race against his peers, and he won the Berkeley Hills Road Race, Cat I. He later became the cycling coach at Stanford. A phenomenal man and human being who would be more than worthy of an interview. I highly recommend you look up Tim Nicholson.
