Well I've ridden a 8" travel bike round sherwood pines and didn't have to get out of the seat or even have to stop pedalling over obsticals. My rigid saracen was completely different, hanging off the bike everywhere, hopping, pedalling skidding and all sorts to keep it on line. My current Marin, (retro with 100mm travel) is bang in the middle, slightly slacker head angle with the forks but still a 130mm stem and flat bars, just wider than usual is perfect for my riding.
The way I see it is old skool bikes and riders ride hell of a lot different, just watch videos on YouTube comparing old to new.
Yeah, but which was the most fun?
I've blasted over ground on a crosser that I had to carefully pick a line over on a trials rig; exhilerating, but no skill involved other than hanging on for dear life with a maniacal grin on me fizzog!
Each to their own...
