OP is making Erik's bike shop sound like it's a big box Dick's Sporting Goods or similar. It isn't, it's a bike shop with small stores, albeit a small midwest chain. If Erik's now sells Cervelo (didn't last I checked, but it's been a while), then it shouldn't be an issue getting it serviced there...or anywhere else. FWIW I take both of my bikes (one Colnago, one Specialized) to Grand Performance in St. Paul. The former was bought there, the latter was bought at Erik's and is not sold by Grand. Nothing against Erik's, I just prefer Grand for service work.
