Overview
Available in most every size (black or white), so that all can enjoy the quality urethane used in 50/50 wheels. The 56mm and 58mm are great for flat setups, while the larger is good for anti-rocker setups and/or the speed demons out there.
PROFILES
56mm wheels use a flat-round profile that has a thin flat strip in the center.
58mm wheels use a bullet profile (rounded).
60mm and 65mm are with a round profile.
The 65mm wheels are big, so fitting onto skates will depend on the frames and soul plates being used. IW has free returns (contiguous 48 states), so just do not use them if having trouble and send them back.
