When I came to get my full suspension bike serviced (Stumpjumper) the shop wanted (Can't remember the exact figures) £55 for the service, £45 to service the fork, £80 for the rear shock, £80 for the 'brain' (part of the rear shock) and £15 for new bearings. Not to mention brake pads etc.
Anyway, with parts they wanted nearly £300 just to service it!
