3. Same answer as #2. Remember, straight forks are raked too but the rake is set by the angle of the blade/crown interface, not by the blade curve.
4. Depends on the carbon fork.
Isn't there a slight variable in the "length" of the fork? Specifically, the stright line distance from where the fork seats in the head set & the axle center line. A difference in this length will slightly raise or lower the head tube & therefore change the rake. Correct? Or, have I have too many cups of coffe today? Bob
