No, those symmetric mounts are from another planet.

Well then either make them out of kryptonite, or that old standby, unobtanium.

This is the one everyone wants but can't find. Someone on the list made a one-off not long ago.

That leaves me with the dilemma of what to do about that shifter boss. I've looked in vain for a cable stop adapter. If I'm going to cut off the boss now is the time to do it before I put a finish on the bike.

Would this help you with the downtube conversion?

If you are interested in some 80s SunTour/Sakae touring comoonents, pm me as im going to tear down my converted 1980 Voyageur 11.8 and build it back to stock.
Suntour barcons, Sakae SX triple, Nitto rando bar, etc.
Im sure ill toss em on the FS page too so im compliant round here.


Really neat frame- enjoy the build and the adventures!

I don't remember exactly what was involved, but I think I just disassembled the Suzue "Crane" bell, and drilled a hole in the little flat section between the bell mount and the curved part designed to clamp onto a stem or handlebar, then cut off the excess. I was able to just sandwich it on top of the right downtube cable stop, reusing the screw that holds the stop to the boss. A bit of blue Loctite, and I never had any trouble with it.

In fairness, the bell never got a ton of use, but it wasn't due to ergonomics. It wasn't any trouble to reach for a quick ding -- I'm just not much of a bell ringer by nature. The trails around here aren't so crowded that I can't just slow a bit, and find a way to pass with ample room and a simple "Hello" or "How's it going?" as I overtake them just slightly faster. My bells pretty much just get used on walkers / joggers with earbuds, or dog walkers, more so I don't surprise the dogs.

No, my color scheme is based around the paint that I already have... after all this is supposed to be a budget project so I can get my feet wet in touring without sinking my wallet.

Some teaser pics soon.

Thanks to @gugie and @cdmurphy for posting photos of their beautiful bikes, setting a very high bar! If mine ends up half as nice as those two I'll be happy.

Primer is on and sanded. First color base coat is on.



And thanks to everyone who posted various ways to deal with the shifter bosses.

I actually made it myself. (I'm a machinist/welder, so it's right in my wheelhouse.). I think you can get to my Flickr album just by clicking on the photo, but if not, here's a link to my albums: https://www.flickr.com/photos/[email protected]/albums

Sorry Brent, I didn't mean to hijak your thread. Looks like you're making great progress. What's the final color scheme going to be?

No need to apologize.
Often times the hijacks are as informative as the thread itself!

Hopefully the final color scheme will be revealed in the next two days, after I finish sanding the color coats and apply the clear coat.

Clearcoat done. Ready for buffing. This project will probably stall for a couple weeks: My wife and I are headed to the Sierra Nevada in a couple days for some camping, hiking, fishing, and general goofing-off.

Beautiful!
You don't see much of that caramel / butterscotch color these days. If you are interested in decals, there's a guy on Ebay who started making some for a Centurion Super LeMans a few months back, but was very receptive to doing a set from artwork I'd made up for my Centurion Semi-Pro. I just got them in the mail a few weeks ago, and they're perfect. Nice and thin, and the artwork came out fantastic.
I've got very detailed vector art for the earlier 1976-78 logos and graphics, and could probably whip out a "CENTURION" logo in the proper font for your '84 that you could have done in that brown. That, and a Tange #2 tubing decal and it would look like it just rolled off the showroom floor.

Mic drop! And he leaves town...

Looks fantastic! Total class. Frankly that is going to look better than the somewhat cheezy 80s paint job that it came with. I'd probably just leave it graphics free myself, or use the earlier graphics. Maybe stick a Centurion headbadge on there if you can come up with one.

That's the Brakes
Cantilever brakes are interesting devices with a logic all their own. I won't bore you with all the details but there are plenty of threads in the archives about setting them up. These are the brakes that came with the bike.



They actually fit the 700c wheel conversion but i decided to replace them with brakes that have a longer lever arm and that have a tension adjustment. I found a set of Dia-Compe 987s at the Trips For Kids Recyclery at a reasonable price and installed them with new pads. I kept the straddle cable short to provide maximum braking pressure.



Unfortunately these brakes were designed for mountain bike levers which pull considerably more cable than road levers. With the pads adjusted as close to the rims as possible the brake levers would pull all the way to the bars and the brake feel was very spongy. So I lengthened the straddle cables and the problem was solved.



I'll leave them like this for the first test ride, then adjust accordingly.

That looks great.
I think it's a common misconception that there's one good way to set up cantis with regard to straddle cable placement and length. Really it depends on the design and shape of the arms themselves and I've seen brakes with drastically different straddle heights and lengths brake equally as well when worked on sufficiently.

The "ISO and For Trade" thread really helped with this build.
Thanks to @nlerner this bike now has a very nice Ultegra triple crank set and thanks to @unworthy1 It has a beautiful Suntour triple front derailleur and pedals!




I spread the dropouts to 130mm and installed an 8-speed Ultegra wheel set that was waiting in the bicycle basement for just such a project. Stem, bars, brake levers and shifters all came with the bike. This generation XT rear derailleur is my favorite large-capacity derailleur. I try to always have one around. Handlebar tape came off another bike that I want to change to black tape. The 32mm Pasela PT tires, cables, and the chain were the only items I bought new.




Today's test ride allowed me to fine tune seat and handlebars as well as confirm my suspicion that, even with the 30-tooth small chainring I am going to want a larger cog than 26 for loaded touring.
