I'm about 50% through my first MB build on an old Ironhorse Maverick mountian bike. My son recently finished a build on my old 1983 Bridgestone Spica large frame 12 speed and has changed the chain tensioner since these pics were taken. I'm getting legal with the lighting, mirror, helmet, M2 and plate, and other things. It's nice to find a very nice and informative forum!
