The Speed wheels from K2 are purpose-built for speed. 85A ensures the right mix of grip and speed whilst the ILQ9 Classic bearings that are mounted supply effortless roll speed.
They are mainly built for replacement of worn out wheels for speed skates from K2 which typically run on 6mm axles. For this reason, these wheels are supplied with pre-mounted 6mm spacers. These can be replaced with the more commonly used 8mm spacers, which are sold separately.
