Bones STF Street Tech Formula™ Annuals (STF) V5 Sidecut Wheels - 52mm 103A

52mm in diameter by 30mm wide. A low profile wheel for those who want their board close to the ground and a fast flip. It’s lightweight, and you’ll notice the difference after an hour-long session.

The hardness is listed in two ways on the manufacturer’s spec sheet, 83B and 103A, which represent the same value. Bones measures their harder wheels on the B scale, which runs twenty points lower than the A scale. Regardless of the number you see on the packaging, this is the wheel.

Street Tech Formula Urethane. It withstands street impact without developing flat spots, which is what usually kills a hard wheel before it wears down. At 103A, it barely deforms, so it slides without sticking and maintains speed on smooth ground. On rough surfaces, you’ll feel every bump.
