|Fork Rake's effect on handling?||Ken_IF|

|Hi, I have a IF Crown Jewel, which came with a 50mm offset fork. I'm interested in putting a carbon fork onto the frame, but the majority of the forks that I've found (Alpha Q, Ouza Pro) come in 43 or 44 mm offsets. I understand that this will slow down the handling of my bike by increasing it's trail. But by how much? Very significant? I have checked and overlap shouldn't be a problem for me. All that's left is my concern regarding the handling change. Thanks in advance.|

|I assume you are on a smaller sized frame based on the 50 mm of offset. Changing to a lower offset carbon fork will slow down steering a noticable amount. Only you can decide if the handling is too slow however.
If it matters, Colnago uses a 43 mm offset fork for all models and the smaller frame sizes use fairly slack head angles. Not too many people claim their Colnago steers like a truck.

do a Google search for "bicycle steering geometry" and you'll get lots of links; the above link is the result

|With the head tube angle and frame size, a comparison of the amount of trail can be made to other brands (like Colnago). If the trails does not exceed Colnago's, I wouldn't consider it to be excessive. Colnago has about the largest amount of trail of any brand that I know of.
If you don't know the head tube angle, it's pretty hard to make an evaluation.

|Oops, sorry. I had run the calculations, just forgot to post them :).
It's a "stock" geometry Crown Jewel -- 72* head tube, 50mm offset. Current trail is 56.9mm (I keep calculating 55.3mm for trail, but maybe I'm using the wrong diameter for the wheel).

|my seven Tsunami, slack 71.5 head angle and 50 mm rake IF fork. I wanted to maintain similar handling, so I went with a 50mm reynolds ouzo pro fork (yes, they do make one), which can be found at excel sports, or for about $100 less at www.wisecyclebuys.com. They have a listing on the classifieds on this site, I used them for my fork and would recommend them highly.
