    Strengths:    Easy modulation (progressive), very powerful, 3 year warranty from Shimano, beautiful finish.

    Weaknesses:    Expensive, but I did a lot of shopping and got the best deal at BicycleBuys.com. Ultegra is probably a better value. Buy Ultegra but use the new Dura ace 7800 pads. I think they are the key to the progressive, powerful feel.

    Bottom Line:   
    This review is for the new 2004 7800s. The pads are very progressive and easy to modulate as compared to my previous Ultegra. It looks like Shimano even used some of the design cues from Ultegra. Very powerful and it doesn't hurt that they have a Titanium finish that matches my Litespeed.

    Weaknesses:    105 feels just as good but cost half the price.

    Bottom Line:   
    Used these brakes on my uncles Trek 5900 with Ksyrium wheels. I was able to nose wheelie going downhill with my hands still on the hoods. Very fade proof (that's more a function of the pads) and crisp feeling. No mush.

    Strengths:    Weight (or lack thereof) and winsomeness.

    Easy adjustments and reliable and easy-to-use QRS.


    Weaknesses:    Mushy feel, all-or-nothing response.

    Bottom Line:   
    Light and pretty. Not a bad brakeset, but could be better--and certainly a better value. It's the second-weakest link (after the bottmon bracket) of the Dura Ace group.

    The Dura Ace 7700's have a rather mushy feel that translates into an "all-or-nothing" response. I've felt this, even after rim cleanings, pad and cable changes, overhauls, etc.

    Yes, the front will lock up your rear wheel and the front will pitch you over the bars if you use it alone and too hard. But the same can be said for most brakes.

    Besides, I can't remember the last time I needed to come to a dead stop from full speed. You might argue that because I used to race and was a bike messenger in NYC (not on these brakes!), I have better-developed reflexes and skills than most riders. Still, I think that it's more important that a brake can moderate your speed than to stop you on a crack in the sidewalk.

    These aren't bad brakes. But I've used better--and certainly gotten better-- for my money. (Examples: the Dura-Ace and Ultegra Dual-Pivot brakes from the 8-speed group.

    Strengths:    Pucker power

    Weaknesses:    Price- or bum it off of your uncle. By the way, he got the Lance bike used with only a couple hundred miles for about $1500.

    Bottom Line:   
    I just rode the on my uncle's Lance Armstrong replica. I tested them on a four mile downhill (after I climbed it of course) at 40+ MPH. All I can say is, it is quite scary nose wheelieing at 42 MPH while trying to enter a gravel strewn corner. YEHAWWWWWWWWW! Don't Skimp on brakes. GET SOME TYPE OF SHIMANO OR CAMPY. Don't make the same mistake I did.

    Strengths:    Power and finish.

    Weaknesses:    Modulation, maybe. I haven't tested the Campy Record/Chorus units. Value.

    Bottom Line:   
    Whoa! After reading the reviews below I thought maybe I had made a bad purchase.
    So, I tested what these guys with bad reviews were saying.

    I have a hill where I can hit 42mph at the bottom. I weigh 190lbs. The brakes worked terrific and slowed me very quickly. Perhaps modulation could be better. I had to feather the rear lever a little to keep the rear wheel from locking up.

    Another reviewer complained that the pads did not hit the rim squarely. I can say that my calipers are perfectly toed in 1mm. The pads are not supposed to hit the rim parallel or they will squeal.

    As for the "stupid light" review, I decided to check check out the calipers on both the D/A and Ultegra. Though I could not just weigh the arms, I found the D/A calipers to be slightly thicker where the pads are bolted on. Thicker is generally stronger.

    I am 100 percent pleased. I guess the Ultegra are a better value, but not a better brake. I would also question what people expect from their brakes. They are not disks with anti lock. They have very small contact patches (tire/road and pad/rim). Also, folks should not expect to stop from 40 to zero in twice the time it takes to stop from 20 to zero. They should have paid more attention in physics class.
