The Guerciotti Cross Disc Cyclocross/Gravel Road Bike in 58cm size is a high-quality Italian-made road bike. Durable aluminium frame. With 18 speed shamano gears. Equipped with 700C wheels, disc brakes and a carbon fork. just had a service £35, fitted a new seat (£40), new inner tubes and marathon tyres (£130). unfortunately the ergonomics aren't agreeing with me.
