The Marzocchi Z2 was a badge of honor, and still is. A heritage that says a lot. Over the last twenty years, bicycles have changed dramatically and progress has never looked so good. Z2 E-Optimized forks are made specifically for the rigors of E-Bikes with a more robust chassis and increased durability by adding material to strengthen critical areas. The design also uses tuning originally made for Enduro use, which suits the needs of E-MTB and general E-Bike uses.
