    New question here. Chainstay Angle & Front Derailleurs


    Shimano has Front Derailleurs available for different Chainstay Angles - 63-66 degree & 66-69 degree. For what reasons do frames use the above Chainstay Angles? It appears that SRAM only specifies Front Derailleurs for chainstay angles between 66-69 degrees. Can somebody inform me as to the significance of the difference of using different ranges of Chainstay Angles?

    Thank you,

    The 63-66 degree chainstay is generally found on very small bikes - like XS or Small in some cses, and on most a lot of Women's Specific bikes. SRAM probably doesn't make one because of cost vs. profit (aka: Return on Investment). Not exactly a big market for these front derailleurs.
