Progress presents the latest revolution, a wide rim with a U-shape design made of DYNAMAL aluminum, an ultralight and extremely resistant material.

The Sonic outperforms and outweights many carbon wheels on the market at a fraction of the price of its rivals.

The 20mm inner width improves cornering grip and increases rider comfort.

The Sonics come mounted with NITRO Straigh Pull Hubs with high precision, low friction NITRO CERAMIC bearings. These hubs have been tested for more than two years by PRO cyclists with excellent results.
