Okay, I just looked at all the wheelbase sizes and it seems the difference between '17 and '18 model increases the smaller your frame goes.
The smallest frame wheelbase for '18 starts at 1000mm up to 1053mm, whereas '17, it's 989mm to 1054mm.
So as you can see, at the largest size, the wheelbase are identical and Spesh probably has to have a minimum 1000mm on the smallest size in order to accommodate the increase tyre clearance.
