About the Campagnolo Record 10 Speed Cassette In competition every little detail counts; that's why steel & titanium were used when producing Record sprockets. The perfect teeth design results in a perfect synchronization between shifting & chain movement. The six larger sprockets are divided in triplets, which are mounted on special frames to increase rigidity. The teeth of the Record sprocket set have an Ultra Drive design that integrates the chain & chainwheels of the crankset. This ensures long term fast, precise & consistent shifting. The four largest sprockets are made from Titanium.
