Good point, Loser do you have any idea what i kind of rake your current fork has?, Basically make sure there is not a large difference between your the replacement and your current one, Other wise, you May end up with a poorly handling bike(Very slow turning, Or overly responsive)

I know approximatively how much rake there was on the original fork but i just don't know how to calculate it. Am i suppose to mesure the angle or the distance between the point on the ground where a headtube prolongation would arrive and the point right under the fork end.

**** that last one was hard to explain.

Because the original fork was a 27'' with a 27'' wheel front and back, but now I have switched to 700s.
Switching to a 700 fork will change everythng so I guess that since the headtube is a little more close to vertical the rake of the original fork wont't be the best for my 700 fork.

Sorry for my ignorance, forget the last post.

I know how to mesure the rake now. With a 27'' fork, my headtube was a bit higher than it will be with a 700, this difference will alter the headtube angle, making it steeper, how should i deal with that, do i need a fork with more rake than the original one or less, or the same?
