What is Tange Infinity tubing?
The Tange Infinity tube has a thickness of 0.9mm on the ends and 0.6mm in the middle. The Tange Prestige tube has thickness of 0.7mm on the ends and 0.4mm in the middle. The Infinity weighs 287 grams, the Prestige weighs 207 grams. So you’ve saved a little less than a fifth of a pound in the top tube.
Is Tange tubing good?
It quickly became synonymous of high japanese quality. During the golden ages of CrMo bikes,for road racing,and moreover BMX and MTB, Tange was considered as the best tubing maker by the biggest bikes brands, as well as be spoke frame builders.
What is a double butted frame?
Double-butted – The tubes are thicker at each end to provide additional strength at the junctions but thinner in the middle to reduce weight. A frames down tube is most commonly double-butted.
What is Tange steel?
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.
What is Tange Prestige?
Prestige is, however, much stronger and somewhat harder than non-heat treated steels. Tange’s brochure says it has 30% more tensile strength and 12% more surface hardness than either “C Company” or Tange’s own No.2 chromoly tubing. These qualities have been verified by every frame builder I’ve talked to.
What does butted mean in bikes?
Butting a tube refers to changing the tube’s wall thickness by removing excess material that isn’t needed for strength or performance.
What is a butted bike frame?
Butted tubing has increased thickness near the joints for strength while keeping weight low with thinner material elsewhere. For example, triple butted means the tube, usually of an aluminum alloy, has three different thicknesses, with the thicker sections at the end where they are welded.
What is a butted frame?
Among steel frames, using butted tubing reduces weight and increases cost. Butting means that the wall thickness of the tubing changes from thick at the ends (for strength) to thinner in the middle (for lighter weight).
Which frame size is best for cycle?
Bike Size Chart/Bike Frame Size Chart
| Height | Bike Size |
|---|---|
| 5’7” to 5’11” (170-180 cm) | 16 to 17 inches |
| 6’0” to 6’2” (180-188 cm) | 17 to 19 inches |
| 6’2” to 6’4” (188-193 cm) | 19 to 21 inches |
| 6’4” or taller (193+ cm) | 21 plus inches |
What are double butted spokes?
Double-butted spokes: These are lightweight spokes that are thinner in the middle (e.g going from 2mm to 1.8mm and back to 2mm again) to save weight and reduce ride stiffness, without compromising on wheel strength.
How is double butted tubing made?
After heating to over 1000 C, a hole is pierced through the center to form a very thick-walled tube. The wall thickness and diameter of this tube are then progressively reduced by hot rolling and cold drawing until it is sized for the butting process.
