Mornin' folks- thanks for tossing my hat in the ring! I do build bicycles full time but don't have a proper site up yet- in the meantime you could visit the link in my sig and see a few examples of my work. Besides myself there are quite a few people building bicycle frames in the area, some full and some part time. Ezra is definitely a great guy and does some amazing work. Actually I think he is coming over to my shop today... as for Traffic, Spencer has "hung up the torch" as they say. For a few more options you can check this listing a local website put together recently: NYC Bike Builders | The Bird Wheel
Hope this helps- If you'd like to discuss further off-forum feel free to shoot me an email or PM here. Cheers!
