My bike was new/old stock bargain and as a result I have a different fork, there is a 2mm difference in trail to the orginal spec (I rode the orginal spec) and it makes a MAMMOTH difference.
Lot less stable, sharper steering, no hands requires concentration depending on the road surface, that sort of thing,
BTW there is nothing wrong with that 3T fork, but you should compare the exact dimensions, which you will be able to find easy enough, and also find out why it is changed.
