Shimano DuraAce BR-9000 Brakes (Road)
The Shimano DuraAce 9000 series appeared on the market in late 2012. The groupo includes new brakes that are more powerful:
Long, fast descents demand confidence. Dura-Ace brakes deliver, with a new symmetrical dual pivot design and twin bearings reducing pivot friction and improving efficiency and controllability. Along with new low-friction BC-9000 cables, Dura-Ace brakes give smooth, light operation with excellent modulation. Available with conventional mount or direct mount for aero road bikes (BR-9010).
10% more power than BR-7900
Smooth and light operation with increased modulation
Also available in direct mount version (BR-9010) for aero applications
I retrofitted my Moots Vamoots RSL road racing bike in early November 2012 with the new Shimano BR-9000 brake calipers, replacing the earlier generation BR-7900 calipers.
I ride and race a lot of steep mountainous terrain—
Big tire bonus
The BR-9000 brake calipers provide a much improved tire clearance profile— so much so that I was able to pop in my cyclocross wheel with a Schwalbe Ultremo 700 X 28C clincher tire with ~3mm clearance to spare (tight tire fit on the brake pads when inserting wheel, but once in, the tire clears the caliper and fork just fine).
The FMB Boyaux 700 X 27C tubular tire also fits and is a great riding tire.
On the bike
What I noticed right off the bat was increased breaking power, yet with excellent modulation. I adjusted to the new performance very quickly. These brakes are AWESOME.
I am pleased with the BR-9000 brake upgrade. Brakes can never be too good— they’re what stand between you and the (unforgiving) pavement.
