    Fork rake

    I have a pista and want to get a carbon aero fork for it. However I can't seem to find any forks with 28mm rake. If I went with a 40mm would it make that much of a difference? It is also a 1" steerer tube.

    it's not quite as simple as just looking at fork rake.

    If the two forks are the same length (axle->crown) then going from 28mm to 40mm rake will decrease your trail by about 10mm. Which will make things a bit less stable.

    However, the road fork might be a bit longer than stock pista fork. Putting a longer fork on will effectively slacken the HT angle, thus you'd need the extra rake to give the same trail you had before with the shorter, 28mm rake fork.

    the 28mm is aggressive which is needed for track use. A 40mm would relax the ride and give you more of a road type feel. There was a thread on here earlier this week on carbon forks you should check out that explained the difference the rake makes in handling

    This is a common misconception. Adding rake to a fork while keeping fork length constant decreases trail, and consequently makes handling less stable. So as baxtefer was saying you'd want more rake if you were adding a longer fork, in order to keep trail constant and in theory, to keep the handling from becoming more stable.
