Fork Rake
I am looking to replace my Bontrager Race fork. I am looking to not go back with ButtRanger, and I'm liking the look of the Reynolds. The problem is that my current rake is 45mm and that's kind of hard to find. Oval and Alpha Q have a 44mm which I may actually like better. Reynolds only makes 40 and 43mm. I can see 44 as not being a big deal but less than that has me worried that it could be a bad thing. What issues could I run into here?

The more rake you have the less trail you have, and vice versa. Plugging some numbers in shows that going from a 45mm fork to a 40mm fork (assuming a headtube angle of 74.5*, I took this number from the CAAD9), your trail will go from 40 mm to 45 mm.
This will make your bike more stable, but less precise. If you want better handling, go with more rake. If you want more stable, go with less rake.
What does this mean in the real world? I have no clue.

Then it will change your trail from 48mm to 53mm if you go from 45 mm rake to 40 mm. So you already have a lot more trail than a CAAD9 (everyone's favorite bike around here, hence my example bike), which is going to make your bike more stable. If you want to make it a little more sporty feeling I can't think of any reason not to go with a 40mm rake fork.
I'm pretty sure that you can't change rake enough (without a weird fork) to get clearance issues between the wheel and downtube, but I could be wrong.

So contradicting what I said earlier if I could get a Bontrager Race X Lite fork brand new in box for $49, with a 40mm rake that would work ok. If I understand what you are say Flat to give my bike the same rake as a CAAD9 I would need ~43mm rake? 40mm to me sounds like its just to short.
