Filante SLR

Wilier Filante SLR - The Lightest Production Aerodynamic Racing Bike Bike designers always have something they can improve. One design can use some more aerodynamic touches, while another might need to lose a little weight. With the Wilier Filante SLR, the Wilier designers have tried to create the best of both worlds: the lightest possible production aerodynamic racing road bike. To make good on the first ambition of putting their prime aero bike on a diet, the Filante SLR sheds over 100 grams compared to the Wilier Cento10 Pro. So instead of weighing 990g, the Filante SLR comes in at 880g, which is an 11% decrease. That’s a lot, and it slips the Filante SLR into a lightweight neighborhood that is usually more occupied by other manufacturers’ climbing bikes that don’t focus on aero efficiency. They have managed to get the weight down so much by using a high modulus carbon with a liquid crystal polymer which helps increase the tensile strength and durability of the tubing. Focusing o
