New meaning to dual pivot.

Shimano's stoppers have always proven to be some of the smoothest and most powerful in the business, and the new Ultegra 6800 Brake Calipers continue to represent these qualities in full effect. The new brakes were completely redesigned, borrowing the same new pivoting mechanism as Dura-Ace 9000 to provide you with incredibly consistent power distribution at the rim surface.

As with the conception of Dura-Ace BR-9000 Brake Calipers, Shimano started from the ground up when designing its new Ultegra 6800 brakes. Shimano used its new 'true' dual-pivot design, which deviates from the Shimano legacy of the mounting bolt doubling as a second pivot. Instead, 6800 has a rear-mounting plate with a center bolt for frame attachment. The brake arms now reside symmetrically over the wheel, and work independent of the mounting plate because of an integrated rolling cam. Shimano kept the cable stop off to the side, but with the new dual-pivot design, any cable pull applies an equal tension to both arms. Taking a step even further, the arms operate on a twin bearing system that drastically reduces pivot friction, and thus makes brake application from the levers a light, predictable, and powerful experience. In fact, Shimano makes the claim that BR-6800 has 10% more power in the caliper than their 6700 counterparts.

The arm placement is now closer to the rim, which, when coupled with an equal pull on each side of the rim, drastically increases modulation. Actuation from the levers is lighter than ever, and with Shimano's new low-friction, polymer-coated cables, you can expect a braking experience unlike anything Shimano has offered before. And for all of you running larger tires, Shimano will also be producing a thinner brake pad option to accommodate up to 28mm tires.

Lighter operation, smoother modulation, and an aesthetic design that's unmistakably Shimano, the BR-6800 is as good as it gets. The Shimano Ultegra 6800 Brake Calipers are available in one size and one color. The calipers are only available as a pair and are recommended for use with the Shimano ST-6800 STI Levers.

Here's what others have to say...


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.

Is this a set of front and back?

Best Answer

Yes this includes a front and a rear brake caliper.

If you need anything please contact me at

Does this brake set come with cables and housings?

Typically the cables and housing are included with the brake levers, not these calipers.


The best I've had yet!

  • Familiarity:I've used it once or twice and have initial impressions

Two versions of older 105, one version of Ultegra 6700s, Campy, Tektro, and now these.

HOLY CRAP! Top notch feel and excellent stopping power. I avoided upgrading to these in the past because of the slight weight penalty. These came on the new bike and I'll tell you the marginal increase in grams is worth the best brakes this side of DA!

Is this price for both front and back brake?


Plenty of stopping power

  • Familiarity:I've used it several times

My last bike had Tektro brakes-my new Cervelo is outfitted with this new generation Ultegra 6800 brakes and boy what a difference. Plenty of stopping power and they look great too. Practice using them-a panic grab at the brake levers will leave you with a flat spotted tire.

Any idea what the reach is on these? I have a new endurance frame bike that came with full Ultegra, except for the long reach Tektro calipers for the increased fork/tire clearance. I would like to upgrade the brakes. Thanks!

These are a standard Short Reach road caliper - 39-49mm.


Crazy powerful

  • Familiarity:I've used it once or twice and have initial impressions

These newer ultegra brakes are ridiculously powerful if they have a good braking surface, say, a good pair of mavics or shimanos etc. Id go as far as to say I was actually a bit surprised how well they work. I would recommend getting used to the way they respond before you go bombing down a big ol' hill at a blistering speed. You cant go wrong with shimano quality and these will definitely not disappoint.

Do I need specific cables with the 6800 calipers?

I have just fitted the calipers to my current cables but I,m unable fit the cables into the caliper recess unless I remove the end ferrels?

If they're anything like the 6700 brakes they are designed to insert the cable straight into the female part of the cable tension "twirl". Toss the cable ferrules Shimano expects you don't need them anymore apparently.

What is the maximum tire size for those, could 700x25c fit in?

Best Answer

Yes..............even if sometimes it is a bit tight just release a small amount of air. Just that simple.

Are these compatible with the Shimano ST-5700 brake levers?

Thank you.
