87/88 3Rensho Super Record Export TT - my Thanksgiving project

Well, last night I managed to tweak my knee well enough to think it best if I didn't ride today. So instead, I cleaned up the 3Rensho TT frame that I picked up on Tuesday. Here's what I know about it so far:

Andrew Muzi at Yellow Jersey informs me it is either a late 87 or early 88 frameset, painted in the Team colors of that era (which team, I don't know). Frame takes a 24" front wheel, 700c rear, recessed mount brakes. Campagnolo vertical dropouts in the rear, over the BB cable routing. Fillet brazed frame other than the BB which is lugged, with a gusset reinforcement between the chain stays. I have been unable to find any photos online of a frame exactly like this one. The closest I've found has been over on the Yellow Jersey website of a custom built 87 frame with a curved top tube and lugs at the headtube.

Paint is in over all good condition. There is some chipping along the drive side chain stay, and behind the front forks, around the rear brake cable guides, and a few others here and there. I took down some of the surface rust with a brass brush on the dremel this morning, and appears all issues are on the surface only. I also applied a coat of wax to the entire frame, which really brought back the depth of the color, espeically the blue. Good news is that the headset and bottom bracket are both in good condition. Headset appears to be a C-Record, BB is Record as well. I slipped my Super Record crank arms over the spindle and appears that they seated nicely. There had been a shimano 105 crank on it, but appears there was no damange to the spindle due to such.

I am picking up the front wheel from the seller tomorrow morning. After that, not sure what to do with it. I have some SunTour parts, and a Super Record group I could build it with. As low as the head tube is, I think I'd either have to put bullhorn style bars on it, or just conclude I'm always going to ride on the hoods of any drop bar I'd put on. Honestly, after cleaning the frame, giving it a good once over, I'm not sure if I'm 'feeling' this bike. I jumped on the chance to pick it up because I didn't want it to become a fixie (there were 3Rensho perusit track frames as it is), and simply because how cool are funny bike frames! However, I think I am, and always will be, a sucker for lugs. Perhaps this one would be better served in the hands of a 3Rensho affectonado who will restore her to original. But for now, at least I can treat you all to some better photos!

a few people have asked about the size of the frame. By my best measurements, it has a 56.5cm ctc seat tube and about a 59cm virtual top tube.


as photoed in CraigsList ad. I'm getting the front wheel tomorrow, didn't buy the rear.






Cleaned up and polished.


Shifters. Not sure what to make of the 3Rensho Dura-Ace AX right lever. Aftermarket? Orginal?


She's not pristine, but all of this is surface only and I treated with some rust inhibitor and waxed to protect. Decided against touchup paint for now.


the only "Lug" on the frame. Also, amazing how pretty the paint is after a coat of wax.

Nice frame , I read somewhere that they are more confortable than they look. You could probably get back a good part of your frame's purchase price with the shifters , I know I paid my frame with the 3Rensho parts that came with it!

There are no Ducks in the pics. We need Ducks. Not just any Ducks, but Mom Duck with baby Ducks trailing along.

Oh, and the frame is still really cool. I'm not sure exactly what to do with it, but it's really cool.

Thanks for saving it from an excrutiating conversion.

You want ducks? I should have stopped by the pond on my way home from last night's ride (the one that I think screwed up my knee) and snapped a few more photos. I took photos on the ride, but nothing worth sharing after I got home and looked at them.

I guess I'll find out when I get it built up. The top tube is probably too long for me now that I've measured it. I'm all leg, and this bike has a lot of top tube. But, as the geometry of this thing is unlike anything I've ever encountered before, it may surprise me.

Hope the knee isn't serious. There is no good time for an injury.

I have to be over your way in the next couple of days. I'll take a drive down your street to get my duck fix.

It might well indeed be a surprise as to how comfy is when built. The question is what do you use it for after you finish building it up...... Still a nice, cool, and unique frame though.

If you're over this way, you have my phone number, drop me a call and you can come see the 3Rensho in person. As far as what to use it for, if it is "that" comfortable I may take it to a club ride for kicks. Otherwise, it'll share 'vintage ride time' duties with the Gazelle A-frame.

Not sure what I did to the knee. Felt a little strain coming off a stop in too low of gear on the ride, but that was on the back of the knee. Later last night I stepped out of the closet and then "BAM" the inside area of my knee just lit up on me. It's feeling 80% better today. I can feel it's not "right" yet, but isn't causing me pain.

I'll give a shout before I head that way.

Back of the knee sounds like possible saddle adjustment issues. Inside of the knee, not so much, and more serious. Hopefully just a tweak and a few days rest will take care of it.

I absolutley promise you will be the only 3Rensho funny bike in the parking lot at RBM before the ride starts!

You going to the Swapmeet down in Deep Ellum Saturday? I went to the first one, not overwhelming, but not a bad way to kill an hour of two.

Back to the game..............

Nice. I would post it over on the fixie forum just to make them salivate. Some hipster would pay you mucho dollars for that bike, but I commend your nobility in preserving it.

my housemate has a 1987 Aero Team Miyata...very similar geometry, even a similar paint job, equally beautiful...the biggest difference i can tell is internal rear brake cable routing, but not a big difference:

http://www.miyatacatalogs.com/2007/1...alog-1987.html
(a bit down the page, can't directly link to the image)

it came with some DA components (headset and seatpost), and after a month or so stint as a fixed gear, he gave it a 600 rear/DA front, Sakae crankset and BB, and laced his own 24 spoke 24" front wheel. a great, very unique, and superaero build

your 3Rensho should be an amazing build, can't wait to see it finished!

That is closer than any 3Rensho I've seen. Probably I have right now is that I don't have a seatpost that'll fit. I'm fairly sure that it takes a 26.8, I have a steel 26.6 that I used for taking photos, but A) it's really heavy and B) I'd rather not collapse the collar of the seat tube any more than I did for the photos. I didn't tighten the bolt as much as I would had I planned to sit on a saddle on top of that seat post. As far as builds, guessing I'll go with my Campagnolo super record group. Though if the SunTour Superbe crank I have fits well on the campagnolo spindle, I may go that route.

Anyone have an early cyclone or superbe short cage derialleur they would trade for a near mint condition Cyclone GT?

The nice thing about this frame is that once you have the basic components you can plug and play in several different configurations.

For example, you could get one of the simple SS conversion kits and turn it into a single speed. Or, set it up "time trial" style witha single front chainring, say 48t or 50t, and a cluster of your choice in back.

Here is a pick of my former Nashbar Aero Sprint for inspiration.

The plot thickens! I picked up the front wheel this morning. Rim is unabled, aero profile, tubular. 24" Vittora Juniors tubular tire (unfortunately it appears there is a cut in the sidewall which is producing a buldge). Hub was horribly annodized on the outside, but spins like a million bucks. Hub looks fimilar, but can't quite match it up. Phil Wood is a possibility, or a Hi-E?! In any case, it's laced radially, 24 spoke. I've already gone to work cleaning up the hub, center area polished up beautifully, but getting the flanges cleaned up is going to take a lot more work unless I unlace the wheel, which I'm not inclinded to do. Photos coming in a moment.

Ok, front wheel photos. A hub ID would be great. I'm not holding out hope someone will ID the rim though.


full wheel




Hub closeup (pre clean up)


Here's where it stands now. Have to let my fingers rest some before going at it again. Dremel is too big to get in between the spokes (may have to ask for that snake extension thingy for Christmas), but the outside I've hit with the brass and nylon brush a little, as well as a polishing pad. Haven't touched the skewers yet.

Looks like an early American Classic hub to me.........I've got some like it. The QR is exactly the same. Judging by the early hub and finish /profile of the rim I'm gonna guess the rim is an Araya.

The only decal on the rim is from the shop it was bought from. I think you are right about the rim being an Araya. Likely a Araya ADX4.

Thanks for the suggestion of the Am.Classic. If the skewer matches, then you're probably right.

edit:

Haha, yeah, the hub is American Classic. I had done a search on VeloBase, knew they looked like an American brand, checked out the Phil and the Hi-E, but neglected to look at the American Classic listing. This is why I made the visual list feature on the site, should learn to use my own features...

I second the notion of it maybe being an Araya rim - I have a track tubular rim that looks identical (except that it is unmachined, of course.)

The cut in the tire sidewall:


Threw a few parts on for fun. May swap over to my Super Record group, the Cyclone GT just looks so out of place and I don't think the chain I have will play all that well with it unless I stay on the small ring (it was shortened for my Gazelle running the Super Record derailleurs).









(no comments on how a TT doesn't need a 12-28 cluster either. )

Well, the 3Rensho did help me solve one mystery. Confirmed that half the spare wheels/hubs I have around here are actually 126mm spacing and not 120mm as I had for some reason thought! Its a lot easier to measure the width between rear dropouts than it is between the locknuts of a hub in a built wheel!

Also think I'm going to pull the suntour stuff and go with the Super Record parts. The more I think about the chain I've got to put on it the more I think that's the better plan. The shifters may be a bit out of place, but I'm not going to swap on a set of campy levers on when I already have the shimano ones installed.

2 hours 27 minutes.

( and the question is: How long will it take Jon to decide to keep this bike after putting
on a Super Record gruppo).
