Tange Mangalloy 2001: Opinions on this tubing?

Hello all. I have 57cm Panasonic touring bike (PT-4500) 58cm. Seems like a very nice bike shimano cantis dual eyelets for rack & fenders and it is made from the Tange tubing I mentioned above.

Does anyone have any experince with this type of tubing? Riding etc. Also any idea where I can get info on Panasonic bikes? The yellow jersey site had a little but not much. I would guess it is late 80's early 90's as far as its age. Thanks.

I had a Nishiki Ultratour with said tubing for many years. Bought it new in the beginning of the eighties. Decent solid Japanese quality, not the liveliest of bikes, not the lightest but a good workhorse at a reasonable price. My guess is that your bike probably is from the mid eighties.

Keep in mind that Reynolds 531 is a manganese-molybdenum carbon steel alloy.

Seamed, butted, manganese alloy tubeset from the late 1980s. Ecomonical but on the heavy side. Used primarily on lower mid-range models and, because of it's extra weight and durability, grand touring models. A good tubeset for the price and intneded use, but like all tubesets, the ultimate ride characteristics and quality have more to do with the geometry selected by the designer and the skills of the framebuilder.

Not familiar with the PT-4500 but have seen the PT-3500 and PT-5000 which seem like nice bicycles for the prospective price points. The Panasonic brand always had a good reputation based on the owners that I've talked to, though I never sold them and have only ridden a few race models.

I have a 1983 US built lugged and brazed Trek 400 road bike made with exactly the same tubing so it must have been used by several manufacturers. The 400 was the bottom of Trek's road bike pecking order in '83 so the tubing must be considered relatively low-line. Trek's next model up the line that year (the 500) used Reynolds 501 Cr-Mo tubing.

My 400 sure isn't the lightest frame I've ever ridden but it's solid and stable. Mine is set-up with a mix of parts-box components, 7-speed indexing, fenders and a rack as my rain/beater/errand bike.

1984 Trek 520

I have an '84 Trek 520 that has the Tange Mangalloy 2001 in the rear triangle and the forks. The main triangle is Reynolds 501. It is a decent setup and have had no problems with it. Like others have said it is not the lightest, but not heavy either. Seems to be a solid combination of steel.
