Whats the most reliable approach to selecting a front derailleur for a vintage bike restoration, considering the vast array of options available and the potential for compatibility issues with older components?
Are there any hard and fast rules for determining the ideal derailleur model based on the bikes original specs, or is it a matter of trial and error? How do you navigate the minefield of clamp-on vs. braze-on, and what are the key differences between the various generations of derailleurs (e.g., Shimano 600, Campagnolo Nuovo Record, etc.)?
Furthermore, whats the best way to ensure that the chosen derailleur will work seamlessly with the existing crankset, chainrings, and shifters? Are there any specific measurements or specs that need to be considered, such as the derailleurs pull ratio, cage width, or actuation type?
Lastly, what are some common pitfalls to avoid when installing a front derailleur on a vintage bike, and how can you troubleshoot common issues like poor shifting performance or interference with other components?
