This is the full shebang and should be done every 12-18 months depending on the riding you do and the bike you have. The Full Service includes everything in the General Service but takes a deep dive into your drive train and fork. 

The crankset is removed to allow for thorough cleaning and inspection of the bottom bracket. The fork is dropped out to allow for the removal, inspection, cleaning a degreasing of the headset bearings.

In the case of a disc brake bike, the callipers and pistons are serviced to improve braking performance, eliminate disc rubbing and bleed the braking system to remove air and contaminates. 

This service is highly recommended if you have an undiagnosed creak, there is a high chance it will be solved through this service.
 
Full Services start at $260 for rim brake bikes and $295 for disc brake bikes and takes between 3 to 4 hours to complete.
