Tioga Power Block's S‑Spec version uses a Cyclex 120 TPI ultra‑lightweight casing, which is thinner and more supple than standard BMX race tyres making this tyre the choice of champions
The S‑Spec version uses a Cyclex 120 TPI ultra‑lightweight casing, which is thinner and more supple than standard BMX race tyres.
It’s built with a folding bead, further reducing weight compared with steel‑bead versions.
Uses Tioga’s UTC rubber compound for the tread, designed for efficient power transfer and grip.
The tread design: a smooth center band for low rolling resistance and directional side lugs / lateral crampons for cornering grip.
Sidewalls are very thin (in the S‑Spec version) to save weight and increase suppleness.
Available in several sizes for 20″ BMX wheels: e.g., 20 × 1.75", 20 × 1.60", 20 × 1‑1/8" etc. Example weights:
20 × 1.75 ≈ 310 g (10.94 oz)
20 × 1.60 ≈ 240 g (8.47 oz)
20 × 1‑1/8 ≈ 200 g (7.05 oz)
