Shimano Ultegra SM-RT800 Disc Rotor

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.

Nice finish with great stopping power!

I have ordered complete SRAM RED e-tap HRD, including SRAM Red Crankset 5236. I have been delighted with biketiresdirect.com price and and speed of order fulfillment. I ordered on Friday evening and my order arrived Tuesday morning even thought I am in Austin, Texas area and without paying extra shipping fees. While I have been waiting on my new Helix Pro TI frame from Lynskey, I ordered for about $500,00 tools for bike. Again, help with order, order execution and shipping, every thing went so smoothly with biketiresdirect.com that it was a joy to order from them. One time I hade to modify my order before shipping, and after receiving, I had to return 2 items. Both times, every thing went flawlessly. Even better, biketiresdirect.com sent me replacement part immediately and I got it next day and then in the same box I sent back the original part. All that with no extra charge. I really love and enjoy my Lynskey bike. To build a bike yourself, believe me, its a big project. But with help I have received from biketiresdirect.com, specifically Nathan, it was a joy and a memorable experience. I will recommend them to my friends, other fellow rider and every one else whos in need of anything for bike. I give them 5 stars only because thats the max available. Believe me, they deserve at least 10 stars.

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.
