25mm rake implications

After a fairly nasty crash and finally attempting to go over the bike to see if there's any significant damage, I've concluded that the the fork is beyond repair. Unfortunately, the crash got me at a bad time so money is tight and therefore, I'm searching for the cheapest worthy fork to replace my broken one ASAP. Throughout my search I stumbled upon this which as always seems like a good deal (Planet-X always do this ridiculous stuff) but the 25mm rake kind of scares me. I have a limited understanding of how rake affects handling but right now I really don't have the luxury of having a choice.

Only problem with having a shit, off the shell frame is limited geo but here's what I found:

TT: 549mm
STL: 550mm
STA: 73 degrees
HDL: 141mm
HDA: 72 degrees
Wheelbase: 982mm

Attempted measuring the rake which was a fairly challenging task (the fork dropouts are also a bit bent from the crash) but initial conclusion is that the rake might not be so different from the Planet-X one. I guesstimated about 20 - 30mm rake (vague, I know but I'm certain it's not the more common 45mm).

Is 25mm rake for general road usage a bit extreme?

Going back to old units, with which I am more familiar, the answer is yes, a one inch (~25mm) rake used to be reserved for ultra short wheelbase time trial bikes. 1.5-2 inches was for road bikes and 2.5 inches for tourers.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
