On my bike I currently have a fork which has an a-c of 374mm with a rake of 43mm. I need to replace it after a crash and have found a replacement which is half the cost of the orginal. However the A-C is 385mm and the rake is 53mm.

The extra 10mm of height is good for me and my bad neck but I am concerned that:

a) the different shape of the fork will affect the handling somewhat. In what way might it feel different?
b) as I ride quite a small frame (52cm) will it bring the wheel closer to my feet too? This is a concern as I use full mudguards and there isn't much room to manouvere.

Thanks in advance. Rob

That much change will totally alter the handling.

More rake will take the wheel further away from the frame/your feet.

53mm is a very high rake - racing bikes are typically 40-45mm.

Typically small frames have slacker head tubes and a bit more rake to stop toe overlap. In the end all you can do is try it. The maths of good geometry is still not well understood, so there is little guidance on what works.
