From Dial tone:
Streamlined, sophisticated and seriously sexy... This is the refined side of Dial Tone. A little bit softer but still perfect for any street or park terrain, the Groove Wheel is available in two shapes and three sizes.
The conical shape provides a grippier ride and a flatter vertical surface for locking into grinds.
*The Groove Conical Shape is only available in 52mm 99a*
