    Strengths:    Worked decently for about 2 weeks than shifting went haywire

    Weaknesses:    misses shifts constantly
    needs works every 2 days
    makes noises


    Bottom Line:   
    I'm an avid junior road racer, I put on around 250 miles a week. I work at a bike shop and have seen every 2010 group. I have to work on my ultegra stuff probably three times a week and I take very very good care of my bikes. For the price paid I can only say it is not worth it. My sram force bike is lighter, stiffer, and longer lasting. I have had to tune up the bike twice the whole season. My shimano stuff constantly misses shifts and needs work much too often. All i can say is get force, it works better. Your paying less money for a better, and lighter (for the weight weeny) group. Dont waste your money. Sram shifters can be rebuilt, if your shimano shifters break you need to get another set. My teammates who use even sram rival have less problems then me. GO SRAM

    Strengths:    The Strongest argument against buying Dura Ace.
    So quiet. So smooth


    Weaknesses:    Not as Shiney as Dura Ace. Hard to build a fifteen pound bike with it.

    Bottom Line:   
    Best deal going on components. I've raced road and cross on Ultegra 6600 and would not race anything else (unless it's on someone else's bill). I tried SRAM Rival for the Weights savings, but switched back after less than a year.

    Strengths:    Tough as hell
    comfortable
    smooth


    Weaknesses:    Probably the weight, which people will inevitably compare to its big brother(or sister, are groupos female? Like boats and ships?)Dura Ace.

    Bottom Line:   
    Buy and forget best describes this groupo. I had my Ultegra since September 2005. 3 years and lots of crashes later, it's still smooth and working! The shifters are the highlight of the group to me. They can be mounted really high on the bars, which provides me with a stable platform when I standing on my pedals. The throw is pretty short and shifting on a dime is easy. Overall I highly recommend this group for anyone who wants a workhorse group with a reasonable price.

    Strengths:    ergonomic hoods
    crisp shifting
    braking power and modulation
    best bang for the buck
    light (unless your favorite Park Tool is a gram scale)


    Weaknesses:    narrow chain means you'll adjust your cables and replace your chain more often
    BB - I just don't like the outboard design
    finish quality on some parts


    Bottom Line:   
    Excellent workhorse group. Lighter than its predecessor. Hoods are more ergonomic, which is something we can all appreciate. Front shifting is quicker. Ultegra 9 had snappy and precise rear shifting; now, it's more refined. Brakes have improved modulation and greater power. I dislike outboard BB's, and Ultegra is no exception. They simply wear out too fast, tick, and develop far more play than a cartridge. 10 speed is more susceptible to misshifts because of the narrow tolerances. You'll need to adjust your cables more often than you would with a 9 speed. The narrower chain also means you'll be changing it more frequently. I drop mine at 1,500; max, 2,000 miles. Finish quality is good on most parts, except for the front mech and chainset. The tenth click is nice because it keeps the gear ratios tighter. In my opinion, 10 speed doesn't offer huge performance gains over the 9, but is more refined and lighter. Honestly, I still find myself throwing a leg over my 9 speed equipped bike more often. It's better in the long run for a higher mileage rider. For a new bike purchase, this is the group level to shoot for. It performs superbly and is a great value.
