I get what you are saying about some lbs I had I real issue when I was a kid with Halfords in Glasgow with a bike they repaired incorrectly and nearly put me under the wheels of a bus literally. The spec dealer were I live are pretty good and at least I’d have direct contact with the person who sold it to me. Also I could put the bike in the van and in 15min be in the shop asking them to sort it out. Or get me the parts. Packing a expensive bike up and sending it off would take time and would require me to be at home during the week for them to collect it and receive it. Plus with that u have all the different third parties to Deal with Shimano the courier and Yt who don’t seem to be that great to deal with at the moment. I just want to spend the right money and enjoy the bike hopefully. The yt is pound for pound on paper a better deal but harder to get hold of and test ride.I have had so many bad experiences with LBS over the years: Inexperienced service people, hard sell tactics, etc. I it is hard count an LBS source as a positive.
A different approach: i have developed a relationship with an independent local mechanic. He is an expert and more than reasonable in his fees. I buy everything online (including my Yeti acoustic bikes, for instance) and have him work on any issues and upgrades. Financially I am way ahead of the game and quality of service is top notch.
If they key feature for paying thousands more on a Levo is LBS, IMO that is an objectively poor decision.
I bought my Levo from one of the best rated LBS in Colorado. They could not do basic fork and shock setup properly, they accidentally disposed of my Bluetooth system code, they were useless In getting the cockpit and saddle setup, etc etc.
