To match this going performance the bike also has appropriate stopping power thanks to the reliable hydraulic Shimano disc brakes. The Ristretto Doppio is available with a high-end dynamo powered front and rear lighting system that includes a Busch&Muller Lumotec Retro Senso Plus front light and Spanninga Pixeo rear light.
