Hilly courses? The Seismic Tailwinds have you covered!
 
The Seismic Tailwinds are push effecient wheels in the smaller diameter range of 83mm. I would consider them ideal for hilly courses where your focus is on push effeciency. With these wheels you will shoot up the inclines!
 
Tailwinds or Alphas?
Both are great for hilly courses!
Tailwinds are more effecient/faster in Pushing. Their pumping game is great aswell but no where near Alphas.
Alphas have the edge in pumping. But duo to their wider contact patch they are slower in pushing.
 
Why Split Duro?
In the front, we use faster, harder wheels, and in the rear, grippier, softer wheels. When pumping, the rear wheels need to have more grip. This is done by using a softer wheel for the rear. Also, with a classic +-0 degree rear setup, a softer, more flexy rear minimizes wheel lift. For the front, we use a harder wheel for fast side-to-side turns and better roll efficiency.
