Thanks for your help, to all who helped.

Speaking of 27"....
If you have one, (I just need 1!) or know where there is a NOS 27" 32 hole
Mavic MA-40 rim, I would be most appreciative. And will gladly pay you for it, or a small finders fee if you point me to one that I can get.
Thanks so much, Dr. D

Hey, may I ask where that magical agreed-upon number comes from? The old tires, which came on the bike, were rated at 85 psi, I think.

75 psi is what I've heard from several sources including Sheldon Brown........ The bike I rode the most during the '80's, a '79 Schwinn Traveler, had steel flat-walled rims, and I remember always inflating the tires to 75 psi and that was also the recommended pressure printed on the sidewall, I believe.............It was surprising, though, when I found recently (during my little "research" project in the basement) that the original aluminum rims on the '83 le tour luxe were flat walled also, because I remember distinctly that the bike came with tires that had a max rating of 90psi, and that's what I always inflated them to.........But for flat-walled rims, I'd stick with 75-80 psi, max-

edit: one bike I failed to mention in my earlier post in regard to my basement "research": I've also got an '84 le tour, and it came with hook-edge rims. So just as a rough guideline, since the '82 Super le tour and '83 le tour luxe had straight-walled rims, I'd say around '84 would be the point in time that bikes of that class (entry to mid level) came equipped with hook-edge rims. Again, my '83 Centurion Pro Tour (a higher end tourer) has hook-edge rims, and the '85 Centurion Accordo (an entry level bike) has hook-edge rims also.

Clincher or tubular? Can get you tubulars.

P.S.: Regarding PSI, I've tried going up to 85 PSI on a non-hooked bead rim. Tire blew off with a bang. 80 PSI is the absolute MAX PSI I would try.

I still ride my '79 Traveler and when it goes on the trainer in the winter, it wears those original chrome, flat walled rims. In fact I still have the original Schwinn Super Puff tires. I ran into a problem in Nov. when I added the fenders I found at the dump. The original Schwinn tires rubbed, so I tried to mount an old 27 X 1 & 1/8 Panaracer. Pumped it up to around 60 psi and the tire just slid off that shinny chrome! Fortunately I had also found a dump bike wearing brand new Kendas that fit! The picture below shows the current set up. The original "Super Puff" is still mounted to the front rim.

I pumped up some 27 1 1/4 tires above 80 lbs forgetting that these rims were straight walled. It was Saturday morning of a three day weekend and half an hour later the bike is on the roofrack and I'm parked outside a hair salon waiting for my wife. A little old lady comes tottering out to get in the car next to mine when the tire blows out sounding like a gunshot. She is non-plussed. She turns, looks at the bike and says "That's not a good start for the weekend."

Those are the ones! I had forgotten what they were called, but how could I have forgotten? I really think those somewhat plump Super Puffs at 75 psi were a big part of the Traveler's sweet ride-

1000 semi-sweet trainer miles on those old steel rims last year. Another 1000 miles of sweet ride on the alloys (hooked bead rims and tires) I run on the road!

Hey PastorBob, sorry to see you missed out on the white Weinmann Hoods last night, close but no cigar! I hate when that happens! (They were too rich for my blood too!)

In light of this discussion, what does anybody think of these wheels on NY Craigslist? No chance that rims from a 70's Atala wouldn't be straight-wall, is there?

Forget him,
If you bought the Mr.Greenjeans model you got red,white,and blue streamers on the bars.

The smooth-walled rims are not made for the 1-1/8" size or hooked bead tires - of which the Panaracers are both.

I would HIGHLY, and I do HIGHLY suggest that the next time a pair of hooked-bead, 27" aluminum rims pop up at (or on anything) at your dump, that you grab and swap them for the chrome rims on your Traveler.

The Panaracers you've mentioned would be nice tires to use on the hooked bead rims as well (You might want to try the 1-1/4" version as well). Pump 'em up to 100 PSI and enjoy the ride.

Incedentally, the Traveler looks splended with the panniers, and especially with the fenders. It completes the bike very well.

Take care,

-Kurt
