Folding Bicycles and Folding Bicycle Accessories by Dahon |
 | | Dahon only uses drawn (work hardened), 4130 chromoly steel, which is 60% stronger than high tensile steel. |
 | | Because of our chromoly tubing's significantly higher strength, we can use thinner, and therefore lighter, tubing. |
 | | 4130 chromoly is why our steel framed bikes feel so "right" and weigh less than many aluminum frame bikes from other manufacturers. |
