The artist formerly known as Michael and then Lungimsam and now Lum Gim Fong, asked of which tubing my 1985 Schwinn Tempo is comprised.
The short answer is "I don't know for sure". The longer answer is longer. There are Columbus Tenax stickers on the frame, and when I worked at a Schwinn shop in 1985, the Schwinn Tempos also had those Columbus Tenax stickers. The fork blades on my bike also have a Columbus sticker. What's Columbus Tenax? It's mid-range, seamed, heavier tubing than SL or even SP. Depending on who you ask, though, things get weird beyond that point. Some people will tell you that Tenax tubing was not available in the Fall of 1984. It didn't exist yet, but the frames that became the Tempo, and the Voyager, and a couple other models were manufactured in the Fall of 1984, in Japan. There is a rumor going around, and I'm perpetuating this rumor by sharing it. The rumor is that Columbus had a pile of cosmetic blem SP and SL tubing that Schwinn bought up on the cheap. Schwinn wanted to claim Columbus, but Columbus did not want them to claim Columbus SL or SP, so they gave them these Tenax stickers, which was a planned tubeset that did not yet exist. So, these 1985 Schwinns have the reputation for being sneaky-nice bikes. I don't know if that rumor is true. What I do know it that my Schwinn Tempo has a 28.6mm seat tube and takes a 26.4mm seatpost, meaning my seat tube has a massive 1.1mm wall thickness and therefore is almost certainly plain-gauge (not butted at all). The 28,6mm downtube does NOT have that sonorous "ring" of thin-walled tubing. The 25.4mm top tube also does not sound to my untrained ear as thinwall tubing. I also know that the fork steer tube has TANGE stamped in it. Michael/Lungimsam/Lum Gim Fong also asked what my light Hillborne wheels are. They are HED Belgium C2 Plus rims, 32 hole, Dura Ace 7700 hubs (with the rear spaced to 135 with an XT axle). DT Competition spokes 2x in front, 2x on the left rear and 3x on the right rear. Brass nipples.
