I recently picked up a Shogun 2001 touring bike from the early 80s. It's hardly been ridden and has a beautiful double-lugged frame with F&R racks, Al fenders and brazed-on threaded fittings for all of those those. It's an 18-speed with Shimano 600 DX brakes & hubs, Deore front & rear derailleurs & triple crank and some odd Deore pedals (see the pic). It even sported the original tires, w/the Shogun name, which are barely worn. But I have a couple of questions moving forward about bringing her back and upgrading.
I want wider handlebars -- 44cm. Where do I get those? What (stem) clamp size do I need to be looking for? Obviously it's not 38.1mm.
It has natural gum-rubber brake-lever hoods that are deteriorated. I want to replace these. What will work? I don't care about the color; synthetic black rubber hoods are fine.
It has braze-on downtube friction shifters. I want to install bar ends. What, if anything, do I need to be watching out for when I do this? Given that it's a 6-speed, do I have to us old ones, such as a set of Suntour 3090s? Or can I use newer ones that are 9 or 10 speed?
I've never seen pedals (see photo) that attach to the crank arms quite like these. There's a fat bolt spacer between the pedal and the crank arm, and they appear to be held on the back of the crank with a bolt. I don't object to these pedals but I'd like to know how to remove them if they ever need work. Can they be replaced with conventional pedals if need be?
