Avanti GIRO ER Road Bike

Whether you’re hitting the pavement for that daily commute, weekend fitness, or venturing off the beaten track on the weekends, the new Giro ER has you covered. A comfortable and upright ride position combined with huge 30mm wide road tyres and wide rims, equals a smooth ride no matter how rough the road gets. Shimano’s new Tiagra hydraulic brakes will make sure that you get all the power you need to that wide rubber, when you need it.
