Our local shops on average will give you a basic fit, and might be willing to swap (like for like) stems if it doesn't involve changing out all the cables and housing runs. They also provide discounts on basics like water bottles, helmets and fenders etc. Mind you, since shop markups on the accessories are like 100%, getting 10% off of these is no bargain; you'd be far better to buy this stuff online. And coming from a shop mechanic here: please please please do not take your new carbon road bike and ask us to install impediments such as racks and fenders or an attachment for a kids trailer. Or (please let me die
a kickstand.
As far as basic service such as 'tuneups', yes, provided as well for a year or two. However, what is provided is twiddling the barrel adjuster on derailleurs, checking tire inflation, checking brake pad wear etc. These are the kind of things that any cyclist (absolutely) needs to know, and so you'd actually doing yourself a long-term disservice by outsourcing these fundamental maintenance tasks. If during the free 'tune-up', problems are identified such as wheel needs truing, or chain replacing, this cost is not covered by the shop; you'd still be better off learning this stuff yourself.
