Gravel, strada bianca and more. Road Plus is an option appreciated on gravel when you decide to tackle a ride featuring complicated terrain requiring traction, support and comfort. Less rim, more tyre, more air volume: Plus means making the most of the benefits of the wider 27.5 wheel, for easy riding over rough terrain, maintaining speed in total safety and reducing fatigue.
