Shimano Ultegra 6800 Brake Calipers

Slow your roll.

Going balls to the wall is fun until you take a corner too fast and end up limping home, resembling a zombie-movie extra. To save you from looking like a card-carrying member of the undead hordes, Shimano redesigned the Ultegra 6800 Brake Calipers, with plenty of inspiration from the industry-leading Dura-Ace, to offer improved stopping power, more sensitivity, and smooth, easy action.

Traditionally, Shimano's brakes have used a single-pivot design, but the Ultegra 6800 uses a dual pivot, which allows the caliper to be placed symmetrically over the tire. Combined with a cable that runs directly out of the middle of the caliper, this gives the 6800 balanced tension, so braking forces are distributed evenly to both sides of the caliper for smoother, more reliable braking. The arms feature a friction-reducing twin bearing system that allows them to pivot extremely smoothly, so you get instant and sensitive feedback from even light touches to your brake levers.

Shimano also designed the Ultegra 6800's arms to lie closer to the rim, which provides more sensitivity with less effort. Feathering your brakes will be a silky smooth experience, and hard braking won't require the grip strength of a gorilla. Even the new brake cables have smooth low-friction design. The Ultegra 6800 is also set up to accommodate thin brake pads, perfect for riders rocking wider 28mm tires.

THESE BRAKES COME AS A PAIR

    We get this question all the time so I want to post it here for some clarity. These brakes come as a pair!!!!!! Front and rear brake including!!!

    is this one caliper or two? The title says "calipers"
    Just wondering if I need to order two?
    thanks,
    Eric

    Hi Eric, these come as a pair meaning they will include the front and the rear brake.

    Good brakes

    • Familiarity: I've put it through the wringer

    Stopping: Compared to what I had before, these brakes do inspire confidence in their stopping power. The brake track of your wheels do have considerable importance here, as do the pads, but the calipers themselves are trustworthy. Works with at least up to 25mm tires.

    Install: I like the fact that they are very adjustable and easy to install. The barrel adjuster is ergonomic and makes setting the width easy. If anything is off-center, there's a screw to deal with that as well. The pads are also easily adjusted.

    I have a 2013 caad10 5 with a 105 groupset but for some reason it came with tektro R580 brakes. will these fit my bike? I'm runnin 25mm conti gp4000s on it now.

    These should fit your bike without difficulty. You could potentially need to adjust your brake cables and housing, but I genuinely have no clue there.

    Worth the upgrade...

    • Familiarity: I've put it through the wringer

    There are a lot of component upgrades that are hardly noticeable but to replace even the 6700 brakes with these 6800 ones is very noticeable and worth it. I have these on two bikes andI definitely recommend them.

    Solid stopping power!

    • Familiarity: I've put it through the wringer

    These are some solid, reliable brakes. Easy to install and have performed flawlessly now for about 1,500 miles. Can't think of anything negative to say. They are what they are - great brakes, great weight at a great price point.

    Value!

    • Familiarity: I've put it through the wringer

    These brakes are pretty amazing for the money.
    Better stopping power than pretty much anything else on the market.
    Quality and Durability are top notch.

    They may not feature the words "Dura-Ace" emblazoned upon them but they will do the same job at a fraction of the price.
    But, they do not say Dura Ace, and they are not shiny, and they do not send the message to everyone in your group that you spared no expense when building your bike, I suppose that is their only downfall.
    Photo below of Shimano's user manual for rim width recommendations. I have run wider rims without issue, 21mm. Which is against Shimano's recommendations, and tires up to 28mm.
    As Tevor says way down at the bottom of this page:
    "These are a standard Short Reach road caliper - 39-49mm."

    Value!

    is it contains front and rear?

    This is for both front and rear. A representative replied to the same question last year already. See reviews below.

    Yes, this is for the pair.

    Unanswered Question

    Will these brakes accept a wider rim 622x19c?

    Excellent Brakes

    • Familiarity: I've used it several times

    Like the rest of the Ultegra name, the 6800 calipers are a fantastic option for the price. Brake performance is good enough to shave seconds off those Strava times as you take descents faster with increased confidence in your brakes.

    The looks are nothing to scoff at either; something sure to appeal to vain cyclist in everyone.

    Outstanding performance

      These brake calipers are an excellent upgrade if going with Shimano. Baby bro of Dura Ace, yes please. Other than the beauty of it... i have gained much more confidence while descending and just riding all around. Setting the correct tension and feel of the calipers is easy. What can I say, you can't go wrong with Shimano Ultegra 6800.

      Outstanding performance

      Stop on a dime

      • Familiarity: I've put it through the wringer

      Increased stopping power and clearance. You cant go wrong with these brakes. I ride a lot of canyons and these have more then enough braking power when screaming on the descent. The give me the extra confident I need to take the corners a little faster.

      Feel free to contact me with any questions.

      Great Stopping Power at a Great Price

      • Familiarity: I've put it through the wringer

      I'm not one who shy away from spending money on quality bike components, but I try to do so wisely. Here's a great place to save money by NOT going top shelf. All the stopping power and good looks of Dura Ace without the price tag. Damn near the same weight too.

      Great Stopping Power at a Great Price

      shimano is the best bang for the buck

      • Familiarity: I've put it through the wringer

      the perform excellent, they last, then only thing better is dura ace

      Good!

        I was received it very faster than I expected.

        Are these brakes compatible with 105 5700 shifters?

        yes, i have a mix of 105 and ultegra 5700, 5800, 6700 and 6800 on two bikes and it all plays well together.

        Shimano's official technical answer is "no". They state that the leverage ratio and mechanism on the X800 levers is required to actuate the new dual pivot brakesets like the 6800. There is a suggestion that braking might worsen if you were to upgrade just the caliper. Most reports I have read from people who have tried say that calipers work great with their x700 series levers and the performance is much improved. I upgraded my whole drivetrain, levers, brakeset to 6800 at a healthy discount and feel that was a smart buy.

        Worth the weight....

        • Familiarity: I've put it through the wringer

        At only 40 grams more than their Dura Ace brothers and providing (in my opinion) equal performance, the Ultegra 6800 calipers are a definite win! It actually took me a few rides to get used to the increased stopping power over my previous brake setup, which shall remain nameless.... but costs twice as much. Accurate, predictable braking, very low maintenance. Surprisingly easy to work on when a tweak here or there is needed.

        Are the compatible with shimano BLTT79 levers?

        Yes, they are! Just be sure to check that your frame takes traditional brakes and not direct mount.

        Great Upgrade

        • Familiarity: I've used it several times

        These replaced the stock Tektro calipes that I had been using for a few years with an Ultegra wheelset. The Ultrega brakes look way nicer and offer increased stopping power.They feel more precise as well, great value.

        Great Value and Excecution

        • Familiarity: I've put it through the wringer

        These are arguably the best valued brake calipers on the market. Fantastic braking power, great construction, and a good price. I'd recommend these for anyone who wants top level quality without paying pro-level prices.
