The Shimano Ultegra BR-6800 components offer an ideal balance of light weight and stiffness, making it the perfect choice for both enthusiast and competitive riders.
The low profile aerodynamic direct mount Super SLR-EV Dual-Pivot design provides superior brake performance and light action. It must be used in conjunction with super SLR levers for correct leverage ratio.

With the Shimano 105 5800 being such an outstanding performer, you'd have to seriously question whether you really need to splash the extra cash on the next level Ultegra components. I did that very thing when putting together my new build, and ended up having a mix of both. The brakes being the most worthwhile investment (with the Ultegra shifters a close second) Everything else is 105. A pair of 6800 calipers will save you just over 40g compared to the 105, and do look sleeker too (if that sort of thing is important to you). But you really do notice an improvement in braking - both in terms of stopping power and effort required to engage them. Okay, not a million miles better than the 105s, but noticeable all the same.
The 6800 braek is good quality but some nuts are missing from package box....
Shimano brakes are better than other brands.
Both my bikes came with non-series Shimano brake calipers and I decided to change to the Ultegras. Really glad I did, noticeable difference - lighter action which improves the stopping power. Look good to!!!
I ordered 2016-FEB.14 for use my new biycycle. Probikekit's price is very competition it is better than korea internal price. but i heard Probikekit's slow shipment before. Actually, I'm little bit nervous. but i received well. it is about 13days shpping days. package's status was good. thank you for the fastest shipments. thanks :)
These breaks went on my bike as an upgrade to 105's. Instantly you can notice improvement in breaking and this gives you confidence to push that little bit harder. They also look nicer in Matt grey. PBK had them at an affordable price so I bought them and I am delighted.
Silky smooth in both looks and performance, the Ultegra brake is gorgeous. Okay, so the performance benefit over the 105 is only very slight, but it is there all the same, together with a weight saving. Well worth the extra money in my opinion.
I've just gone from old Sram Red to Ultegra 11 and the braking is a marked improvement - I nearly went over the bars the 1st time I put these on!! Excellent performance!
Excellent braking - much improved over my old 105 set-up. 6800 can reduce the speed with less power than 105 in long downhill . In this part I like best advantage .
Really like these brakes, bought them to replace my 6700 version. Good calliper action, good stopping power and easy to fit and adjust the way you want them.
Its very good quality and efficency is very good
I upgraded from some no name (think they were Tektro) brakes. There is no doubting the quality of this brake and the new cantilever design is a work of art. However, the stock brakes must have been better than I thought because there isn't much noticeable difference. They stop me pretty well but so did the original ones. These will not rust though.
