Bummer you didn't have a good experience there-
These guys are my LBS #2,
Tenafly is closer, but these guys are my Specialized shop.
It would have been the same owner,
Mark has been at the helm for years.
I only go in a few times a year,
and have bought only a couple of less expensive bikes there (base model commuter and fatbike) over the years,
but I have had nothing but good experiences with them.
This includes help warrantying Specialized parts that were purchased elsewhere.
When I had them convert the fatbike to tubeless,
it took 3 tries and ultimately new technology to make it happen,
but I was satisfied with how they handled it.
(Only charged for parts after the initial install).
If the nice guy has a woolly mammoth beard, that's Clark.
Anyway, maybe try them again as you're hunting down your next ride,
maybe third time is a charm?
It would be awesome to be a few blocks from your go-to local shop.
