Materials in BIke frames

 Project 6 - The Bicycle Frame is a very simple engineering component whose design has not changed much in 150 years. Why is it that recently, a wide variety of new materials, from aluminium alloys, titanium alloys, magnesium alloys, MMC’s and FRP’s are being used? What are their relative advantages and disadvantages?










 Frame itself:

- The supporting structure of the entire bike.
- Comprises of a structure of metal tubes, attached to each other by welds or hollow lugs.
- Most popular/common frame = Diamond/Double Triangle




 Diamond/Double Triangle Frame:

- Front portion = main frame, thicker tubes
- Rear portion = rear triangle, thinner tubes







 Key Factors – Weight and Strength

- How a frame is designed and the material it is made of determine how a bicycle will ride and feel.

- The introduction of the new lighter materials has made it possible to drastically reduce the weight of the bicycle...
