Hey, new to the MTab, spend most my time in C&V. My father in law just gave me this MB-2, and I am in the process of very slowly restoring it, and want a place I can document the progress. Some parts have been replaced on this so dating has been difficult, but from paint scheme and crank and such, my best guess is '92-'93. Not doing a period correct build, for one its in too rough of shape and needs paint and new parts, and two I like threadless stems and riser bars, and trigger shifters too much.
"Upgrade" ideas:
Riser bars
Threadless stem adapter with threadless stem
Rapid fire trigger shifter/brake lever combo
Building up a new wheelset as the old one is in poor condition from weathering
New seat/post
And lastly, new paint, going with all red, with a decal set.
So far, bike has been stripped, and given an oxalic avid bath for rust.
Next step, most likely a lot of prep and treatment, then paint.
