Wanted to post up a few pics and wrap up the build on the 970, since this thread has been dormant for a while. Originally when I started the build I installed the SunTour Superbe cranks and derailleurs. These were original to the bike as purchased by the original owner. After some thought though, I decided to go in a different direction. I already have a couple bikes with a 52/42 drive train, and the 970 has really generous tire clearance, so I thought it would be fun to set it up a bit more capable with a 52/36. So with that decision came a few hurdles. First was the Cyclone rear derailleur, the cable bolt was missing and proved a little difficult to locate a new one at a reasonable price. I considered buying another derailleur for parts, but found an eBay seller offering just the bolt and nut. He wanted a lot for it, but accepted my heavily discounted offer.

Next was the cranks. The Sugino AT triple cranks were cleaned up and converted to a double with a new (used) Sugino 36t. The bottom bracket was a challenge though. Finding information for the correct spindle length online was impossible, and I ultimately settled on the trial and error approach. In the process I purchased a very nice (and also expensive) IRD Tenacity bottom bracket. I was really impressed with the finish and quality, but alas it was too short. Hopefully I will find a use for it down the road. In the end the solution came from my parts stash. I had an old White Industries bottom bracket with a 117mm spindle that did the job. This bottom bracket has a unique design that allows the spindle to move to adjust the chain line. Once in position there are set screws that secure it in place. I currently have it working with a 6s 12-24 freewheel, but also have a 13-28 for steeper days.

I also sourced a new 970 chain stay decal from VeloCals, as well as a pair of period Mavic decals - since one was missing off the front rim. New Rolls saddle, new cables in grey, 700x28 Panaracer Gravel King smooth tread tires and Newbaum's clothe bar tape. Keen eyes will notice that I installed the tape from the top down, rookie move I know, first time using this stuff. I thought about attempting to pull it off and re do, but I was afraid I would just end up ruining it, so I'm going to leave it for now and see how it works out.

Now some pics...
