This is my Nishiki Barbarian, serial number 3C A90021775. Bought for $20 a few years back from someone who had owned it from new. It's my first real project, and I'm looking for input. Should I be considering a full restoration and repaint, or maybe just refurbish and protect. Is there a way to get decals recreated? Shimano throughout, Exage 500LX. Shifters, derailleurs, hubs, crankset. Brake levers and calipers also Shimano, though no model shown. I'm Unsure of the bottom bracket. I've been having trouble with the front shifter/derailleurs, they wont pull onto the largest chainring. I've heard of them sticking after years of use, is there a way to fix this? The bottom bracket also needs a replacement or repair, suggestions.
