The Piper Torch Pro Speed Racing Inline Wheels are good for both track and outdoor marathon skating.They use Piper's specialized wheel formula using Duo-Tech Technology (dual durometer) over a RX5 Helix Race Hub Core.

Duo-Tech dual durometer technology incorporates a softer poured inner band that optimizes wheel rebound and performance, with a harder exterior for speed and durability. The RX5 Core is perfectly balanced in its flex.
