A good transmission on a race bike is essential for the race. At the start, between bumps, pedaling is important and must be efficient. With the new Stay Strong sprockets, performance and efficiency are the key. Light and rigid, its 7075-T6 aluminum is very resistant to friction. A design that increases rigidity and avoids any torsion. All this for a weight of less than 100g!
