Why smaller for cross?
Hello to all -
I have seen several posts that mention sizing a cross frame 1-2 cm smaller than a road frame. Why is this? When you decrease the seat tube length, you also decrease the top tube length. You then must make up for a cramped fit by installing an extra-long stem. It just seems to me that any decrease in seat/top tube (smaller than your road frame size) is asking for an uncomfortable and poor-handling bike, as your weight is now too far forward (short top tube & long stem).
Am I missing something? I am in the market for a cross frame and my road frame measures 57 cm (c-c) at the seat tube and 57.5 cm (c-c) on the top tube. It seems that all manufacturers offer a 56 and a 58. Since I fit squarely in between sizes, I really want to make sure of the correct frame before I lay out the cash.
Thanks for any and all help.
Rgds,
