Fork rake question
 

What would be the difference in changing the rake from 43 to 45? Would there be any effects on the ride?
Thanks

If you buy a different fork, the different characteristics of the new fork will most likely alter the handling way more than 2mm of rake. I doubt you'd notice the difference of 2mm, even if the forks were otherwise identical.
It will also give you 2mm more toe clearance with the front tyre :)

These days, carbon forks vary a LOT in design and handling.
