Willier Izoard XP, Shimano 105 Wilier know the Izoard will appeal to everyone so they've produced versions with different build kits to suit a variety of preferences & budgets. This is the Shimano 105 equipped offering, coming in a little bit less expensive than the Campagnolo Centaur version & of course built to catch the eye of those that prefer the solid reliability of Shimano 105 gearing. A good move when you consider that the Izoard is build for long distance comfort as well as light weight speed, so will be ideal for sportive & club riders who might well be more familiar with shimano components. To complete the picture they have also changed the wheels to a set of Shimano R501. Shimano through & through. Nice.
