  • Best wheels
Color: 103A Annuals V4 Wides Size: 55mm x 34mm
Rode spitfire for 20 years. Would always get disproportionate wheel wear, I do 180s and front and back power slides all day long and all 4 wheels are all still the same size. Also they grip a little different than spitfire, I don’t know how , but I can feel it, and I like it. I’ll never ride anything else. It’s STF or go eff yaself. ... show more

  • Bones 54mm 103a
Color: 103A Annuals V5 Sidecut Size: 54mm x 31mm
I got 54mm i thought they'd be too hard since they're 103a but no they handle quite well. Theyre better than my spitfire wheels and smooth like my oj wheels but with the added hardness.

  • Still one of the best you can ride
Hard plaza/park wheel (tho I use them in the streets). No flatspots, great bark and slide GREAT. If you want a HARD wheel that slides, this is it. Would pick these over Spit 101a every time.

  • Son muy duras, diría 103a
Color: 99A Annuals V5 Sidecuts Size: 54mm x 31mm
Las formas son las adecuadas, redondeadas, el tamaño es milimétrica mente exacto, lo único que no me gustó es que el material se siente muy rígido, como si fuera plástico, es duresa 99a pero parece que son 103a, se sienten muy duras, rígidas diría yo o plástico duro.
