2 UNDERSTANDING GRAPHENE Vittoria s revolution of tires and wheels 2
3 From a TRADITIONAL tire maker to a company pioneering a REVOLUTIONARY MATERIAL. Vittoria s story and our WORLD has completely changed
4 Question: What is Graphene? Answer: Graphene is a recently discovered REVOLUTIONARY material Graphene comes from Graphite, which is a natural mineral You know graphite from the black part of a pencil Graphene was discovered when scotch tape was used to take a layer off a piece of graphite repeatedly
5 From graphite 5 to Graphene
6 Graphene is a recently discovered REVOLUTIONARY material It is as thin as a single atom (1/1,000,000,000 th of a meter). One gram can be stretched to cover over 2,630 m 2. Graphene is 200 times stronger than steel and 6 times more flexible. It conducts heat and electricity with great efficiency. 6
7 Question: What does Graphene mean for carbon in our wheels?
8 Question: What does Graphene mean for rubber in our tires? = TIRE revolution
9 Graphene tires are intelligent Vittoria tires with Graphene are now intelligent. IT S compounds become harder and softer, depending on the needs of the rider. If the tire is rolling straight, the rubber is at its hardest and offers low rolling resistance. If the rider breaks, accelerates or corners, the compounds soften and offer significantly more grip. 9
10 Road tires 10
11 RACING DEMANDS COTTON CASING Cotton casings are synonymous to the ultimate performance in speed, grip and puncture resistance. This is why the cotton sidewall is a prominent feature in the new Competition Series. 16 x le Tour de France 18 x Giro D Italia 7 x la Vuelta 12 x Milano San Remo 17 x Paris Rubaix 52 Olympic medals 100% handmade Quality assurance Racing heritage 11

14 Proof: Graphene improves wet grip 115% % 105% 100% Rubino Pro Rubino Pro with Graphene 95% 14 90% Wet Grip
15 More info on Graphene in road tires 3 compounds 4 compounds Background: The impact of Graphene in percentage of improvement fluctuates significantly, depending on the objective for different compounds. Our R&D focus for development per product determines if we use 1 or as many as 4 compounds (4C) for optimal performance. It is not a matter of sprinkling some Graphene and we have applied elaborate scientific research and methods for our remarkable results. As you mention this, it is always safe to talk about double-digit percentages of improvement rather than being very specific. 15
16 Winning with Graphene in MTB 16
17 Question: What does Graphene mean for our MTB tires? greatly increased knob strength longwearing durability confidence-inspiring (wet) grip 17 4 compounds
18 New: MTB e-bike tires with Graphene Graphene provides the increased strength and durability that allows the tires to resist damaging the tread due to acceleration torque of MTB electric engines. 18
19 Graphene for all: bikes including City bikes & e- 19
20 How did Vittoria start its Graphene journey? Vittoria meets Directa Plus Directa Plus had figured out a process to mass-produce pristine Graphene. Vittoria and Directa Plus research and develop together A practical and scalable method for adding a graphene-based material G+, to carbon-fiber products like wheels and to rubber for bicycle tires, was discovered. Vittoria launches the fastest bicycle wheel in the world, Qurano The performance and lateral stiffness of the wheel are revolutionary. Vittoria launches Graphene in performance cycling tires The fastest, best overall and best training tire in the world will start a revolution in tire manufacturing August
21 Will graphene be used in all Vittoria tires and wheels? That is the ultimate goal. Graphene is a premium material. Vittoria targets its high-end performance products first. 21
22 Is Graphene expensive? In short, yes. It impacts the price of Vittoria products with Graphene. However, it offers a huge increase in value for money. More speed, more grip, more strength, less punctures, better durability. 22
23 What are the competitors doing with Graphene? Vittoria does not comment on activities of competitors and/or partners. 23
24 IMPORTANT GUIDELINES We NEVER discuss : Our detailed application process or any critical step in this process Application challenges we have conquered Amount of graphene applied (not even in %) Unannounced future developments 24 Also note: Graphene is not magic. It is highly complex material
