Another fun fact about chain stays is that modern bikes are not symmetrical on either side of the vertical plane. The drive-side chain stay is noticeably thicker on the right hand side (drive side) to deal with the very high stresses in this area.
This photo shows this asymmetry quite clearly: http://velonews.competitor.com/files/2010/09/IB2010_cervelo14.JPG http://velonews.competitor.com/files/2010/09/IB2010_cervelo1...
- msandford 11y agoThat looks to me like the non-drive-side is thicker, rather than the drive side. It also depends on the bicycle. I've got a '53 Schwinn three speed that's made out of what seems like gas pipe and it's perfectly symmetrical. A number of my old steel road frames look similarly, and so does my current titanium road frame.
- J-dawg 11y agoThat's a good point! I completely got it the wrong way around and didn't look at the image properly before posting it. The non drive side must be thicker because of the torsional force on the frame when pushing on the pedals. Too late to edit my post!
