Performance + versatility = maximum satisfaction. Racing 4 is the classic trick up your sleeve, because it gives that extra something, whatever the terrain. 
It's light with a responsive medium profile offering an enviable superiority and eyes fixed on performance.
Our R&D department has capitalized on experiences from developing similar rims to create this package suited to diverse requirements, which makes no attempt to disguise its noble pedigree.
The 35 mm profile is a winning combination of great appearance and great performance. This medium profile makes all the difference on the flats at cruising speeds, but is no less excellent uphill, with agile and powerful relaunches.
