1973 Super Sport Sunset Orange
 

I got this from a coworker for FREE... I didn't even have to go pick it up!! It had a mattress saddle on it so I had to provide the Brooks. Other than that I changed out the awful derailleur(s), I used a GT450 (off of a '74 Le Tour with a bent frame) up front, a Suntour VGT-Luxe in back. I removed the twin-stick and used a pair of Suntour downtube shifters I had. I kept the original EVERYTHING and even took the original bars and stem off as one piece as the tape was in okay condition. I used the bars and stem off of my Le Tour donor and I covered them in shellacked hockey tape finished in twine. I'm waiting on a tru-vativ adapter and I'm going to pull the (original) cranks of that Le Tour and ditch the kick-stand... Any recommendations on a BB cartridge? This bike is a sweet ride. So sweet that it went from a spare for friends to ride (due to the frame size) to my new favorite!!http://bikeforums.net/attachment.php...hmentid=337367http://bikeforums.net/attachment.php...hmentid=337368http://bikeforums.net/attachment.php...hmentid=337369http://bikeforums.net/attachment.php...hmentid=337370http://bikeforums.net/attachment.php...hmentid=337371http://bikeforums.net/attachment.php...hmentid=337372

Nice! I'm too new at this for any BB recommendations, but as freebies go I'd call that a win.

This has been the summer of free Schwinns for me... I got a '74 Le Tour (NOT the wrecked donor bike) from a different coworker...

Nice find, make sure that stem is not above the minimum insert line, looks really high for a Schwinn.

And here I am buying bikes like some kind of sucker! :lol:

Maybe a Shimano UN55. I think they're around 20 bucks. Older 105 stuff is available in good condition in abundance if you're looking to go that route...

Must be Super Sport week. I just picked up a blue '73 with Brooks for slightly more than free. I'll be BB shopping too so let's compare notes.

Wow, that's nice. Got me thinking...was it a good thing I passed up the '72 Lemon Yellow SS for $200 or not?.....Kinda want'n a Super Sport all of sudden!

What spindle length would I use for a Schwinn Le Tour crankset?

You'll have to measure your old one and get as close as possible with the Shimano. I think they make them in 2mm intervals.

These fillet-brazed rolling sculptures remain surprisingly affordable, especially when missing the original saddle. Once you learn the queues that distinguish them from their electro-forged siblings, they seem to start popping out of the bike frame spaghetti piles. They're special enough to warrant repair/reuse/restoration, yet common enough that you don't have to worry about destroying some rare artifact if you modify it the way YOU want it.

You'll need something like the TruVative BB adapter to accommodate a cartridge BB and three-piece crank.

Definitely. There are bargains out in the wild!

Save 1/2, a UN26 is $13 and more than adequate for a free bike. OEM on a $700 Trek 7.2 FX.

The old high end one piece Schwinn crank on this model was not changed from the 40' to the 70's and is not readily interchanglable with other cranks. I would suggest you put new bearings in it and keep as is.

Well, except for this:

Well if you figure the wieght of a bb converter, BB and average alloy crankset you get 3 plus so not a lot of gain for a lot of work and dollars.

+100 They are all I use when I replace worn out bbs. $9.95 from Jensen USA, free shipping for orders of $50 or more. And they price match everybody.

I have the cranks, I'm waiting on the adapter, which wasn't much money ($19 shipped IIRC). I think I'll go with a UN26, which is another $20 ish. So we're at $40, and the work isn't a detriment, it's 75% of WHY I am doing this, and why I am spending the money. It's my hobby and it's fun!!

OK, I'll go down the rabbit hole.

I've got a Campy Comp Triple crankset which weighs 788 grams, and a Centaur cartridge BB which weighs 233 grams on my '73 SS. Together, they weigh 1,021 grams, or 2.25 pounds. That's a triple, mind you. I can't find the weight of the BB032 TruVativ adapter, but it's CNC machined aluminum with steel bolts, and is significantly lighter than the bottom bracket. I can pretty much guarantee you the triple crankset, BB, and adapter weigh less than 2.5 pounds. That Ashtabula crank without the pressed fit cups is over four pounds, and really doesn't offer a lot of flexibility in changing chainrings.

It was certainly worth the effort to me, but I acknowlege it wouldn't make sense for everyone.

Best one on the market, IMHO!,,,,BD

Not to mention the kickstand weighs a little over a pound too. You can also dress up the gaping hole with a chrome handlebar end cap.,,,,BD

I'm no physicist, but isn't losing 1lb of rotational weight like losing 3lbs?

I'm not a physicist either, but I think when folks say that, they're usually talking about rim and tire mass rotating at the periphery of a wheel. To me, weight is weight. The 24" Super Sport frame weighs 7.05 pounds without headset or BB cups, so my challenge was to save wherever else I could. The wheels are Mavic Open Pro 700C on Campy Record hubs. Ready to ride, the bike now weighs 26.4 pounds, which isn't too bad for a straight gauge chromoly bulletproof bike with gearing from from 24.7 gear-inches to 116.5 gear-inches.

I have some sew-ups with Dura-Ace hubs that I want to re-lace with clinchers. Probably a project for winter time. I'm debating on weather or not to order the tool for the kick-stand or to attempt the washer method I saw on youtube.
