Shift Unlimited
Flat, Freestyle, and Anti-Rocker frames all have advantages, and with the Kizer Shift Unlimited, you no longer have to pick between them. This revolutionary approach enables skaters to quickly switch different wheel settings based on their demands and skating style.
Kizer’s Shift Unlimited idea consists of a single base frame skeleton that accommodates three different blocks: a flat block for street, park, and bowl skating; an anti-rocker block that works flawlessly with small anti-rocker wheels (45 to 49mm); and a freestyle block for unrestricted grinds and creativity.
Layon Chang / BRA created the design.
The Shift Unlimited, which incorporates rocker spacers, allows you to roll on practically any combination of wheel combinations, including:

Flat:
Bearing bosses rockered UP – Max 55 mm wheels
Bearing bosses rockered DOWN – Max 60mm wheels
Hilo (rockered UP outside, rockered DOWN inside) – 60 mm outside, 55 mm inside
