|I think I can use 40 or 43 degree fork. What would you do.|

|I would go with the 40 mm rake fork. 74 degrees is on the steep side so the 40 mm fork will give you a little more trail. One exception to this however, for crits the faster steering may be advantageous.

|40 will be a bit slower then 43. As far as I recall looking at charts 40, 43 and 45 fall into "stable" zone, though 45 is almost borderline. You also need to take into consideration bar width, stem length (wider bars and longer stem retard steering input) and most important your likes.
I am running 45mm rake on 74 with 40cm bar and 9cm stem, which should put me on faster side but it feels pretty stable even when I am down on aerobars. However, my seat is pretty far back /longer then avg thighs/ and that generally adds to stability. If you prefer "forward" position go with lesser rake.

|I think I agree with the others, 40. I've got a 43 on a 73.8 head tube and it's a bit too quick for me but ok.

|have something to do with the size of the frame, and not just the head tube angle? We're talking mm of rake (not degrees) aren't we?|| |
