DA 7700 although just shy of being 30 years old, seems to be a big favorite of BF members. I'm still amazed at how well both sets of DA 7700 brifters on my bikes work, the shifting is fast and crisp,...

I have a mix of Dura Ace 7700 and 7800 on my road bikes. I especially like the DA 7800 brakes and outer chain rings. In my opinion the Dura Ace 7700 grupo is the best-looking and perhaps the...

I have DA 7700 brifters on both of my "good" road bikes (89 Eddy Merckx, and 92 Paramount). Both bikes shift perfectly after 1000's of miles ridden. My wife's Cannondale R500 had 9-speed 6700 Ultegra...
