Odyssey La Guardia Socket Drive/Spline Drive Sprocket
A total redesign of Odyssey's popular MDS sprocket. With a built-in full guard, this sprocket lives up to its name, helping to protect your chain from anything you can throw at it. Sprocket thickness increases towards the guard area for greater strength. Compatible with all chain widths. The supplied adapter allows these otherwise Socket Drive sprockets to double as 19mm Spline Drive as well.
