well i commute almost exclusively on my bob jackson world tour which is nearly new. its kinda vintage feeling because of the quill stem and canti brakes, but i may seriously consider commuting on the new to me miyata 912. i got it running tonight and took a spin around a few blocks. the bike i awesome but i am really firmly convinced that i no longer want to ride something where i am not fairly upright. i will be digging out the technomic stem for sure!
