Subject: Re: [CR] Big frames ride better?


Has this subject morphed from what I wrote about someone selling his favorite bike because it was "too big"?

To keep this subject on topic, I'll go on record by saying that Specialized was the first company I was aware of that made each frame with a clean slate design. In spite of my distaste for their recent business model, I give them credit for giving the industry that. It forced (or enabled?) other manufacturers to do the same or close to it.

Also, being 5'8", I can only speak from what I've deduced with regard to my tall customers over the years. There have been two developements I have seen for tall riders. First, oversize tubing seems appropriate for most very tall frames. That also enables the frame to be made with a more generous top tube which seems proportional. Second, the tendency to put riders on smaller frames seems to have resulted in fewer truly good fitting tall frames (by this, I mean over 60cm). I think that is down to the reluctance of dealers to stock frames in the 63cm range.

This is veering off topic so I'll invite off list discussioin with anybody who wishes to further discuss it. I think it is one of the true tragedies of the bicycle market place.
