Spitfire Formula Four Conical Skateboard Wheels - floral bighead (99d)
I love the conicals for that extra contact area, and these are the perfect size and duro for me. Not too grippy, not too slick. ??

I had tried the conicals full but we're too wide for me,tried radials slim but were too skinny. Conicals are just the perfect width, perfect smooth ride and grip. Have then in 52mm & 53mm and they're excellent for both street and skateparks.

These have a 101d hardness, so that means they are going to be real hard and slide very well.
