What's the reason for it. Super Record....
Well..... since a long long time all manufacturers have had a top of the line bike. The mega-expensive super lightweight one. The one that is so over the top and super expensive that they barely sell any of them. Sometimes they exist only in photoshop
. This bike has been equipped for the last decade with Record. The lightest and most exclusive. The flagship of all manufacturers used a Record group. DA was always there, and outsold Record many times over on the bikes they sold (and Ultegra in turn outsold that). Then Red came, and Record was an orphan. All the flagship models which rely on two things (price and weight figures) switched to Red, because it was the lightest and most expensive (aftermarket at least). SRAM offered the manufacturers great deals for OEM Red groups, so for the manufacturers it was win win.
Campagnolo needs Super Record to retake the crown. That is why one more sprocket too. The numbers count.
Shimano are also feeling the threat. SRAM has awesome distribution, unlike Campy, so availablity isn't an issue. It has the required carbon, the weight, and the wow factor.
Interesting times people!
