bikeman.com $112.55 shipped, not too shabby. Any tips from previous converters? My current setup is a Trek 1400 with 105 downtube shifters/FD/RD. It's a double/7 spd cassette. I'm kind of clueless when it comes to adjusting derailleurs, so I'm hoping all I need to do is pull and replace cables. Attached is a before shot, I should have it done later this week.
