So I started working on my cheapo winter bike project last night and learned something new; 21.15mm steering tubes and stems existed up until the early 80's on Schwinn bikes and BMX (still std. for budget BMX bikes?). That said, I grabbed this frame off a buddy already stripped down to the frame, fork and headset ... no stem. I considered using a BMX stem because I can't seem to find a road stem in 21.15mm but I'm sure it will not be long enough. I don't want to spend money and time changing the fork and headset, I just want a 21.15 stem close to 11cm ... help or suggestions, these things seem to be MIA.
