...more on Stiffness (with regards to Bikes)

Being a larger dude, I can really test the stiffness of a bicycle.  This is especially important on a road bike while climbing and sprinting.  Some things I've seen lately that interest me are below...

The FCC (Fisher Control Column) 

 

BB90

The integrated bottom bracket has two main advantages. 1) It is a stiffer, more efficient structure that transmits more power from each pedal stroke 2) It allows for bigger tube junctions coming into it. This creates a wider chainstay bracing angle and correspondingly stiffer rear end

More cool Fisher Cronus stuff...

Consistent fit across all sizes Too often, the ideal fit is established for a 56cm frame size, and then the further you get from the mid-size, the greater the compromise. To achieve consistent fit and handling characteristics, Fisher took control of the following: Fork rake & trail There are three unique fork offsets to maintain consistent trail figures without adjusting head angles and compromising handling. Stack There is a consistent 20mm increase in stack measurement with each size. This ensures the relative hand position on a 45 is the same as on a 61. Reach There is 6mm of reach increase by size. This ensures a consistent fit progression. There is no overlap between sizes and no guessing on sizes.
