My father in law wants a bike, but he's VERY intimidated by gears, and doesn't even want to tackle the "problem" of learning how to work a bike that has both front AND rear gears. (the horrors!)
However, he needs some form of gearing to handle the rolling hills at his age and health. He's not THAT old, and no a bike isn't an unsafe gift...and it's partially for his health that the entire family wants him to have it. He just currently leads one of those horrible sedentary chemically augmented American lifestyles. A little time on a bike should fix that.
I'm converting a Fuji Touring into a 1x9 for him. I.e. replacing the stock TruVativ Touro road triple with a Truvativ Isoflow Single 42t crank. Of course, I'll need a different BB (Power Spline)...but I'm having trouble determining which size.
Has anyone here done something similar...and what size did you use?
