Sharper acceleration and altered gearing - with a 13-tooth 428 front sprocket
The listing specifies a 13-tooth 428-standard front sprocket and gives key dimensions: 20mm specification, 34mm mounting hole spacing and an 18mm inner diameter. A lower tooth count on the front affects final drive behaviour and is reflected in user feedback.
