1982 Trek 412 winter build; graphic stem shifters, turkey levers, and dork disk
Winter project pretty much done. I got an 82 Trek 412 a year or two ago in a 3 bike purchase for very cheap. It had all stock components I believe except perhaps the seat. It sat for awhile, as I have a couple others in that category.

I, like many here have lots of parts, so over the winter I built it up as I wanted to try the Ishiwata 022 tubing and compare to my 83 Trek 700 in full 531. The 700 is set up as a sport tourer as I am old and slow, so I had to do the 412 at least a bit differently.

When done with the 412, the only stock parts left were the headset and front derailleur. I decided to make this an all day rider. I’ve been accustomed to stem shifters and turkey levers on my 73 Schwinn Super Sport that I’ve had since 1975, so this build harkens back to that. Those items plus a triple crank and 35mm tires are what makes this one different enough from my Trek 700 to justify the build.
It was in decent shape but needed a bit of touch up. Bars are Nitto B115. Stem is a cheap one from Amazon. .Hubs are some first generation Dura Ace that I got with mismatched 27” rims. Weinmann concave rims from nlerner here in 700c were close enough in ERD to relace using the same spokes. A very nice early Shimano triple crank came from another bike purchased cheaply, and the 28, 36, 46 rings on it gave nice gearing with a narrow 14-30 Suntour 6 speed in back. A nice vintage Shimano BB and a 119mm spindle were used. A long cage VXgt didn’t play nice with this frame so a lowly newer Shimano was put on. I believe the derailleur hanger on this bike sits a bit lower, so the beautiful VX wasn’t used as the shifting was a bit lazy with the upper jockey wheel being a bit too far from the sprockets. The Suntour ratchet stem shifters from the co-op are SO nice shifting. 27.2 seatpost is from the co-op and replaced the stocker that had no rear offset.
Some Weinmann 610 center pulls and levers came from an old Motobecane from the same group bike purchase. They lined up nicely with the new 700c build. As the Weinmann concaves were the narrow version, two quick releases were needed for wheel removal. Braking is nice, but I thought of trying the Tektro 559s perhaps in the future. Of course cotton bar tape and a mirror were added.
I have perhaps a hundred miles on in now. Most of my bikes have 32mm tires which I am very happy with, but I was building something a bit different and went with 35 Paselas in the standard version without the pro tite anti flat protection. With thes at 50-55 lbs, the ride is very nice. Overall I really like the feel of the frame and components. The seat is a vintage B15 to give all day comfort just like on my old SS. I added a new frame bag of a style I have never used and a computer I had from another bike. I guess I am ready for those longer all day rides. I hope the stem shifters, turkey levers and dork disk didn’t trigger too many people
The half toe clips are something I tried on a bike for my sister. They are very user friendly. The weather here is getting nice too.

Huge thumbs up for suntour power shifters in any form they come in. Stems make sense and I run them on a motobecane for easy pace gravel rides. I no longer stay long in the drops and prefer gear control vintage and closer to home. Great build and I'm betting those concaves will never let you down.
