I already have a few Shimano bottom bracket spindles I could use. However, I really do want to restore this bike to all Suntour Cyclone components which is why I bought the NOS Suntour Cyclone BB cups when I saw them at a nice low price. Cheers |

Chalo commented on a lack of stiffness in some obsolete bottom bracket format or another, not a lack of strength. I believe Frank would say that CrMo and mild steel have approximately the same stiffness, and also that he would be right. Correct. I don't think Tom understands the difference between strength and stiffness. And as usual, he's misstating my points in general. -- - Frank Krygowski |

While it is easy to say that the Young's modulus of ferrous materials is "about the same" it isn't the same and the higher grade materials are indeed stiffer if not by much. But these higher grade materials allowed for large improvements in power transfer. |

While it is easy to say that the Young's modulus of ferrous materials is "about the same" it isn't the same and the higher grade materials are indeed stiffer if not by much. Now that you've googled "modulus of elasticity," why not give values for two alloys we were talking about? And why not give the percent difference? Quantify! I ask because in reality, the differences are tiny. But these higher grade materials allowed for large improvements in power transfer. Explain. If you take a bottom bracket axle made of steel with yield strength 100,000 psi and replace it with an identical part made of steel with yield strength 120,000 psi, will it transfer more power from the same rider? - Frank Krygowski |
