Which direction is the force bending the forks and where are they bending?
Vertically?
I don't see that it would.
I notice that it has big tyres.sutra_ltd.jpg
The Kona is basically a touring bike with disc brakes so the forks ain't gonna be bending much whether they have a curve or not. But imagine a light road race bike with caliper brakes and straight fork blades, like the Kona's but a tad more slender and thinner walled. The downward pressure of the mass of bike + rider applies vertically, so the straight blade bends over bumps in the road. At a guess I'd say the bulk of the bending will be just over half way down the blade. I have ridden such fork blades and they do bend. Think of all the debating of how to stop straight frame tubes bending, and imagine if, say, seat stays were not connected to chain stays by dropouts. They would bend a lot.
