The record-breaking rebound of the Avenger Hardcore is the result of MPC's patented urethane mechanically locked to a lightweight and finely machined aluminum hub. A world-class race wheel through and through.
The BONT Highroller Inline Skate Wheels have great rebound and long wear. The Highroller has won a ton of World Cup races. What you get, is a one-piece hub with tight bearing seats and tight quality control to perform well on almost any outdoor surface.
A mid-range speed wheel (or high-end crosst-trainer) from Bont, is high-end for most other brands. The Elemental Wheel is a progression from the well-known G-Series (G13, G14, G15 & G16), having a bit better roll, rebound, and grip. It is suitable for any surface, but best used for outdoor road skating. A great training wheel that won't break the bank.
