Shimano Dura-Ace 7900 Double 10sp Front Mech

Elite road racers demand reliable and precise shifting, and with 10-speed compatibility and super-lightweight yet durable components, the Dura-Ace front derailleur delivers.

Features:

  • Compatible with Dura-Ace ST7900 shifters and FC-7900 / FC7950 chainsets only for optimum shifting performance
  • Thanks to improvements in the cage design outer trim is no longer required allowing the rider to focus on racing
  • Lightweight nickel-plated forged alloy chain cage reduces weight and increases rigidity whilst resisting abrasion from the chain
  • Extra wide pivot link and optimised spring tension combined with the ST7900 STI lever gives a rigid, flex free shift while being smooth and light action
  • Forged aluminium construction reduces weight without sacrificing durability
  • Hard-wearing Dura-Ace finish
  • Maximum capacity of 16 teeth, for use with outer rings 50-56T
  • Weight: 67g (braze-on)

Answer: 
This set up will not work. The front pull required by the shifter to move the 7900 FD is different than the 7800 FD.

Answers

Answer: 
Braze on - это особая конфигурация рамы, обычно встречается на карбоновых рамах и рамах нестандартной формы. Для таких рам нужен передний переключатель с креплением Braze On.

Во всех остальных случаях используется крепление Band On.

Диаметр указанный для данного товара - это диаметр нижней части подседельной трубы велосипеда, к которой крепится передний переключатель.

Answer: 
Привет,
1) диаметр - это диаметр подседельной трубы в мм
2) band on - это переключатель с хомутом, размер которого указан и зависит от диаметра подседельной трубы
3) braze on - переключатель без хомута вообще, крепится прямо к раме в специальный зажим (подходит только к рамам с такими зажимами)!
Удачи на дорогах!

Answer: 
They are different mounting standards; the Braze On mount version bolts directly to the frame by means of a special plate on the frame (photo below for reference).
The Band On version is the more traditional clamp version, which is dictated by the diameter of your seat tube.
