Zunow Trionic / TT multi-sport coming out party

With the recent threads here on classic Japanese bikes / future book publication and another on dumpster diving, thought it appropriate to intro this project.

I've been short on time for bike projects but being anxious and for too long this one was stashed in the attic.

The acquisition of the frameset alone is another story, though in brief was literally a dumpster find. An owner from a LBS I know found it one morning in his dumpster. Although the bike is unusual and rare, the scenario of others junking or abandoning bikes at the bikes shops in college town is common. Mostly the case where if its dirty and scuzzy and time for one to move back home, they simply toss things away.

Fast forward and its now mine Owner of the shop knew I would breath life back into it and ride as meant to be. That being used in local yoko, amee tri- events plus my crave for riding something older. Clip on aero bars and an old steel bike is my style. I've also declined modern TT loaners (I'll demo ride but no way want to risk damage at some comp. event.)

I've just about finished gathering up mostly period build components, laced the tubular wheelset, soon to cram assembly time and goal to give it a shakedown at the upcoming Dairyland Dare. It has battle scars but the paint scheme continues to trigger the Geiger counter rather well.

Est. year of production is 1987 / 88.

(Sorry for the bad pics and by using my old phone. My sweet old camera gave up.)

I gave up attempting to match the paint and airbrush the nasty stuff. Pictures don't show it but there's four colors in each of the green, yellow and whatever pink tones. Fortunately its straight, rust and ding free.

With exception to the rear brake bridge it features much like the Z-1 model.

I don't know what the single boss and hole is used for on the underside of the downtube.

Somewhere I read Zunow was putting out 60 frames per month at the original shop and with very few workers. Not counting the outsourced produced frames, thats impressive when also considering the level of quality.

Now please don't cringe on my build selection. I do get it and where this bike should sport nothing but period Dura Ace or Superbe Pro, but I have different reasoning. This entire project runs of what a bike on the top rack at Walmart cost plus its a purpose built tool for what I plan to use it for, that likely being limited. Next, I wanted the Suntour shift group from the same city of Osaka. Though its sort of sad at the same time it was Suntour's first index (also friction switchable) and beginning of the end of the company. Produced only two years and when Shimano dragged Suntour to litigation.

Here we go-

This Zunow has proprietary tubing by Tange so its only appropriate to use the cool Tange tapered roller bearing, much like the Stronglight A9 type.

[IMG]DSC_1787 by carrera247, on Flickr[/IMG]

Have yet to see the stance of this bike and measure bb height, though being TT inclined, probably is lower. Going with a matched 4050 series Edge crank with 170 mm length arms. First time for me trying Suntours oval rings. The style is both ugly funky thats growing on me. The hidden bolts plus the pattern resembles some cute cast markings on the fork crown and bb shell.

Click bait

[IMG]DSC_1785 by carrera247, on Flickr[/IMG]

Crazy thing is when I acquired much of the 4050 stuff, I blanked out and forgot this frame had a front derailleur braze-on mount. I only had the band clamp type. Finally, a NOS unit appeared and listed in France. LOL

Of course now that everyone seems to be hoarding Suntour index cog freewheels, the price is quite telling another choice is the fine and bargain budget Sachs - Maillard.

For now I'll give this a go at the hilly Dare event.

The front hub is Superbe Pro and tapers both edges of the flange. Is there a big 'no-no' lacing with the heads inward?

Funny thing and ironic, I'm going with a same era Dura-Ace on the rear. If neither had a label, you'd swear they are a matched pair!

Rims are Araya ADX-4 / front and rear are 28 hole. Had good luck with them in the past.

Meh, at least these are reliable and trued like as machined on a lathe. NO LUmPy. Skinwall a must :-)

[IMG]DSC_1852 (2) by carrera247, on Flickr[/IMG]

I caved in on being period correct but I'm using my old clip-on bars and need some saddle forward. I start with this and see what goes.
(And thanks to a forum member offering it up in the sale section)

Rudi is da MAN!

Can't get over the work this guy does!

Period correct Selle Italia Flite ti rail! Its been a long time since having been on one. Had two fine bikes stolen (Colnago and Kestrel) both having these saddles when first on the market. This is really a feel good moment for me, sort of a throwback and much appreciation for RHM talent and time in making this.

Things on hand, might as well use them. MKS platforms are not my usual and rather I'm a cleat type. Have no clue where these neat Salmo straps came from but they match the font letters on the frame.

[IMG]DSC_1780 by carrera247, on Flickr[/IMG]

TT self supporting and need to carry plenty-O fluids. I'll use this Advent cage on the downtube but skip mounting anything on the seat tube. The smart aero engineers say mounting anything on the seat tube makes for an air brake. LOL

This old set-up will be hanging off my azz.

Interesting claimed inventor / designer sketch from '88. Though I'm using my originals as acquired (I think in 1991).

Saddle is awesome! Never realized the hummingbird looks similar to the Campy flying wheel logo.

Love the bike and build. Edge stuff is cool - - I have a Bottecchia that was spec'd with a bizarre mix of grey painted Campy and matching Edge. All the stickers are neat.

The downtube braze-on is for holding an "air bottom basement" and I think my Miyata 912 has one. I'll leave it to you to figure out what an air bottom basement actually is.

Edit: Guess "Air Bottom Basement" is a CO2 holder: https://www.bikeforums.net/classic-vi...-basement.html

zoowy mama! Spectacular frame...I've used mks pedals on my vintage bikes but I've been gradually changing them out for campy pro fit's as I find them.
Looking forward to the finished build and ride report.

You could get some slotted cleats for those pedals.

^ Tom, the MKS pedals are model GR9. Is there some kind of slotted cleat adapter?
(edit: Possibly something I could fabricate with ally plate stock.)

I have other pedals and shoes with slotted cleats but thought I'd try these out. Surprisingly light in weight.
