Anybody have a good recommendation for a bike shop in NYC for maintenance on my 90’s steel frame road bike? Upper Manhattan would be ideal.

Tread bike shop on Dyckman Street - https://www.treadbikeshop.com/

That's the first one that came to mind for me as well. There's also Toga on West End Ave and 64th.

Any time someone mentions "Upper Manhattan" Tread is gonna come up. They've practically got a monopoly on the Uppermost Manhattan Cycling Community...not because they're such a great shop, but because the local competition pretty much sucks. I mean, within ~20 blocks who else is there? Manny's? Arrow Bikes? puh-leeze...

In fairness, the quality of Tread's service has gotten significantly better in the last ~3-5 years. But if your bike is in need of some genuinely attentive professional service by experienced professionals, you may want to expand your area a bit farther south.

I mention this only if you ever need something beyond basic maintenance pertaining to steel framesets, i.e. a frame realignment or repair after a crash, etc, but if you're willing to come into Brooklyn, I personally take all of my steel bikes to Harvest Cycles on Myrtle. They are a very old-school shop in that they have a frame jig and alignment table and also offer fabrication and paint in-house. I plan on having extra water bottle cage bosses and a few other braze-ons added to two framesets this winter. All-around great guys offering unpretentious service dedicated to keeping well-loved bikes on the road. As far as I know, they are the only shop that offers these kinds of services in-house.
