Campagnolo Super Record X Wireless 13 Speed Cassette The Super Record X 13 Speed Cassette delivers a wider gear range for demanding gravel riding, offering up to 48 teeth for steep and technical terrain. It provides smoother, faster and quieter shifting, with consistent cadence in all conditions. Campagnolo has developed a new cassette generation drawing on experience from Ekar 13, optimising space and retaining the N3W freewheel standard without adapters. The updated tooth profile and Black Chrome finish reduce noise, limit wear and improve long term durability. Gear steps are calibrated for single chainring use, ensuring smooth progression without abrupt jumps to maintain rider rhythm and efficiency.
