Steering Head Rise and Fall
ОглавлениеOne of the interesting results of rake/trail is that the steering head falls slightly as the front end is pivoted from center to either side, and it rises as the front wheel is turned back toward center. The greater the rake, the more the rise or fall. You can see this for yourself. Straddle your bike, get it balanced vertically, and observe the elevation of the top of the steering head as you turn the handlebars from straight ahead to either side and back to center.
Now, remember, gravity is pulling down on the bike, which is supporting perhaps half its weight on the steering head. So gravity actually helps turn the front end away from center and resists the front end returning to center. That’s not a problem, since steering head rise/fall can be balanced against other steering forces.
