Yeah, that sounds about right.
When my LBS built my new road bike, I didn’t pay anything directly. If I had stuck to the standard configuration of the bike (a 3T Strada), I would have saved money by ordering online. But I wanted a pretty custom config (upgraded wheels, power meter, Force eTap AXS Wide rear derailleur, 10-36 cassette, different sized chain ring), and because of the pandemic acquiring the parts was quite a hassle. They had to order an RTP frame, paint it (which I paid for), etc. I’m super happy with the result.
I want LBS like this one to survive, so I am happy to pay. The owner and head mechanic is a former pro world tour team mechanic, and he is teaching his craft to the next generation. My bike setup was perfect, from the perfectly aligned disc rotors to my fit. He has put me in touch with lots of people (e. g. a former pro turned bike fitter) and knows his stuff when it comes to bikes.
