Some bikes come with a recessed drop out whereby they require some extra components to best manage their Pinhead anti-theft system.
This OEM kit is ideal for Trek (TM) bikes that require that extra level of detail.
To get this kit just order it with or without a Quick Release key and it's optional to have it customized to your Pinhead Key Code.
Ideal for some Trek (TM) models with recessed dropouts.
