Here a couple of old pics of the 1st conversion of my 1990 Trek 750 with True Temper lugged frame. The frame geometry is the same as the 520 with the only difference being the chain stays are 445mm compared to 450mm of the 520. Used it as a commuter. Currently converting it to a more friendly town bike and grocery getter. Parts using are XTR shifter/brake levers and chain, LX crank, XT FD and RD, SLX cassette, Bontrager Satellite Plus bar w/Cane Creek grips, and a Profile Design stem. Remainder of components will be what is already on the bike. Hopefully it will be done this weekend and can post some pics. Should more closely resemble it's original look.
