Dalje, koga mrzi da cita ceo clanak, evo ga sledeci zanimljiv deo:
I found an interesting article on Dave Moulton's Blog: Frame Design Then and Now. (Dave built the bike I recently added to my collection, seen here). Dave Moulton is about as knowledgable as anyone can be about racing bike design, and in his article he describes how frame design has changed in the last few decades. He confirms that racers of the past rode in a more upright position compared to now, with their bars higher in relation to their saddles. As Dave explains, that change is at least partly due to changing bottom bracket height.
The way he describes it, racing bikes once had much lower bottom brackets than today. His own racing bike from the 1950s had a BB height of 23.5 cm. A similar bike today would have a BB height of 27 cm. (a difference of about 1 1/2 inches). Raising the BB leads to a higher saddle, as the saddle will be raised for proper leg extension. However, the handlebars and stem do not necessarily get raised by the same amount. When the BB is lower, the seat ends up being lower in relation to the bars. On smaller frames, particularly, there is a limit as to how low one can practically get the bars, as the wheel size and fork length are "fixed" measurements regardless of frame size. Interesting to note, at the end of that article, Dave concludes that the racing position one used to see in decades past is probably a good position for recreational riders today."
