Review by NovatoBiker
I replaced a SRAM Rival Front and Rear derailleur that came stock with the bike, and I couldn't be happier. The Rival gear worked - most of the time, but the Red components work flawlessly. They have much better construction, and we'll see how long they last.

Updated a Cervelo S5 to these new front and rear derailleurs, and it works great
