Track bike for a very heavy rider?
Over the past couple of years, I've been riding with a friend of mine who's been using bike riding/racing to lose weight. Long story short, he has anxiety and depression issues for which he isolated himself and ate a lot to console himself, resulting in him weighing 570 pounds. Nowadays he's down to around 330 and is still losing weight. He likes to experience as much cycling as possible, and had a Ti frame built for him for the purpose of riding/racing road and 'cross. However, he never got the chance to ride the track up here in New England before the program ended, so I figured he and I could go to Kissena instead. Would my KHS steel track bike be safe for him to use? I've been looking for some 48H track wheels for him, but no luck yet. If all else fails, I'll have to build them myself.
