What is Tange Infinity tubing?

What is Tange Infinity tubing?

A cheaper tube set was created by Tange in the 80s: Infinity — designed as a good quality but low-cost set for lower-priced bicycles. It was a seamed tubing, which meant that it started out as flat stock. In 1985, Tange hit the big time when they came up with their heat-treated Prestige tubing.

What is Tange MTB tubing?

Tange International Co. is a major Japanese manufacturer of high-quality steel tubing for bicycle frames, established before 1920. They are a rival to the British-based tubing manufacturer Reynolds. Their current tubing range consists of four tiers: Tange Chromo, Infinity, Prestige and Ultimate.

What is double butted tubing?

Double butted means that the thickness of the tubing on the ends is thicker than in the center. So there are two “butted” sides. The tubing can be thinner in the middle because it takes less stress than the ends and typically you will find most breaks or cracks on frames and parts on the ends versus the middle.

Is Tange Infinity good?

Infinity is a very high quality seamed tube, so prices were kept very low, whilst performance was similar to seamless #1 or #2 (or 531 or SL for that matter). A frame made from Tange Infinity weighs at least half a kilo more than an identically sized frame made from Reynolds 531 (double butted, of course).

What is Columbus SL tubing?

Columbus SL was used by a majority of the Italian bike industry during the late 1970s and early 1980s. It is a high-quality double-butted tube set made of Cyclex Cromo Steel. Columbus SLX was released in the early 1980s as the pinnacle of Columbus tubing, made of Cyclex Cromo Steel.

What is a butted tube?

A butted tube is one where the outside of the tube is a constant diameter (usually 25.4, 28.6. 31.8, 34.9, 36.4 or 38.1 mm) and the wall thickness varies.

What’s the difference between double butted and triple butted aluminum?

Double butted is when both ends have thicker walls and the middle has thinner. Triple butted is the same as double butted but the material removal is taken a stage further to make the walls in the middle even thinner.

What is Columbus Gara?

November 2010. Gara is the name of the tubing. I do know that these are fairly heavy and durable tubes. Not found in too many racing frames and If I recall I saw one from about the mid-eighties but I don’t know what year they originated or if Gara is still being produced.

What is double butted steel?

There are two methods used to butt a frame tube. Double Butting—As the tube is shaped, extra material is allowed internally at each end of the tube. By increasing these areas of the tube, the overall tube wall thickness can be reduced, thus saving weight.

What is custom butted tubing?

However, Reynolds eliminate the need for this with bulge-butted seat tubes. These are double-butted tubes, with different thicknesses at each end. A typical tube would be 0.9/0.6/1.2mm thick. At the 1.2mm end, we then bulge the tube so the inside diameter is 27.2, which would take a standard seat pillar.

What is the best metal for a bike?

Steel is the most commonly used material in bike frames. Carbon or high-tensile steel is a good, strong, long-lasting steel, but it isn’t as light as its more high-tech brother, the steel known as chromoly. A workhorse of the industry, chromoly is a light, strong steel.

What kind of tubing does Tange use?

(Tange History) Until the mid-80s Tange was probably best known for their mainstay tube sets, Champion #1 and #2 (later called simply #1 and #2) — cold-worked, butted chrome-moly tubing that compared favorably to Columbus SL and SP tube sets.

Are Ishiwata tubes comparable to Columbus tubes?

In material composition and in specification, Ishiwata 019 and 022 were (like Tange #1 and #2) very comparable to Columbus SL and SP. In fact, many people claim that the Ishiwata tubes were, at least in their surface finish quality, even nicer than the much more expensive Columbus tubes.

Is Ishiwata tubing good for bikes?

Today, in the vintage bike marketplace, they can be a good value. In any case, by some time in the 80s, the Ishiwata tubing was dropped by Trek. Ishiwata ended up going bankrupt in 1993, but some of their employees went on to found Kaisei which is being used by a number of steel-frame bicycle builders today.
