I'm getting a new old bike that has a 1" threaded fork that I'd like to keep. I'd also like to use a set of carbon handlebars from FSA (31.8mm clamp). So, I need a quill adapter or a threaded to threadless adapter or whatever the proper nomenclature for the thing is. I've found two, one by Profile Designs and one by Zoom. Are there any others and does anyone have an option on which is the best product to do this job.

If someone knows of a quill stem that has an oversized clamp diameter that would be even better. I haven't seen one.
