Great stopping power

When one of my rotors was fouled with hydraulic fluid I upgraded both to Ultegra. They work very well and the center lock design makes them very easy to install with just a cassette tool and chain whip.

These were used on new gravel tires/rim and have worked out well. I would purchase these again.

Works to slowstop the bike.

Works well, however after a month or so, starting to have a slight squeal. Not too bad so far.

Use these are my road bike for all outdoor riding. Great on quick stops even after riding through some puddles. I would definitely purchase again.

Love the new design. Performance is excellent. No complaints. Maybe slightly less aero from the side? Seems like the old design had more cutouts that might catch crosswinds less... but I have no scientific date to back this up.

wow is all can say. I have never ridden as strong since adding this fabulous disc rotor. JK, who really knows what a disc rotor does anyway?

My Diverge needed new brakes so I purchased new rotors and pads. Very quiet braking so far.

2nd Set for New Wheel Set

These arrived quickly for installation on a wheel set for my Specialized Diverge. Grips on a dime.

Mounted on a gravel bike that sees a fair bit of road use. Easy to install, no issues. Didnt think the Dura Ace version was worth the extra for a few grams weight savings.
