|One more fork question. I am relatively new to bikes and am getting into triathlons. For the moment I am riding a used bike that seems, to me at least, to have some pretty aggressive geometry (for one thing the top tube is comparatively shorter than the same size trek, wheelbase is shorter, ect). |
Anyway the bike is very sensitive and although I have gotten used to it, will a fork with less rake smooth out the ride. Or, should I suck it up and use the stock aluminum fork? I'm doing tri's so on the aero bars I need more stability. The problem is that the wheelbase is already pretty short, will shortening it more cause other problems. (Everything else on the bike is great)
Since it's a used bike I'm leaning towards just sticking with what I have and maybe invest in some quality tires but I thought I would just toss this one out there
Thanks for any help!

|What kind of bike?
What size is it?
What are your measurements?
Are you comfortable on it?
Do you honestly know enough about bicycles to make an educated guess about geometry and the effects a new fork would bring about?
A)Spend money on upgrades after you have ridden and researched quite a while. You will be better equipped to make such decisions then. You may find that a different bike is a better solution than trying to heavily "tweak" the wrong bike.
B)You've got the rake thing backwards.
C)Good tires are an excellent idea.
D)Say bullocks to all this and just blow money until you are satisfied. This is what most newbies do.

|A short top tube is okay for tri-bars, because you're steering with your elbows, thus the reach is shorter.
For straight-line stability, though, you'd want a shallower headtube angle than what you say you've got. I also agree with Ahimsa, for more stability you need not less, but more fork rake. Someone else can theorize how a longer fork rake would work with a steep steering angle, however. It would seem to me, that putting the front wheel way out in front of a steep steering column would make the very stabilizing, flywheel effect of the front wheel less responsive to steering, understeer, but that the bars would still be twichy on top of the steep column. A steep steering angle would require a smaller fork rake, putting the front wheel closer in for tighter control, like what you have now.
If you want to throw some money into it, I'd suggest perhaps going with a stiffer carbon or steel fork. Some older aluminum forks have had a reputation for being noodly.
