Headset and stem - Road vs. mtb
I'm in the market for a 1 1/8" threadless headset, and a stem. The primary shopping criteria is "cheap". When browsing eBay and Craigslist for deals, is there any real difference between threadless headsets and stems marketed as "Road" or "Mountain"?
I sometimes find it's more trouble than it's worth to try and source stuff on eBay/CL; can someone make a recommendation for innexpensive headsets if I decide to buy new?
P.S. I do realize the stem needs to have the proper clamp diameter for my bars.
