Shimano Ultegra SM-RT800 Disc Rotor

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

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

FAST SHIPPING AS ALWAYS PART INSTALLED WITH NO HASSLE.

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

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.

Building up a spare road disk wheelset on a budget, and BTD was the best price found. Delivery was on time. Well packaged. Now I can handle emergency wheel changes with the spin of the thru axle.

Nice finish with great stopping power!

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.

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.

Typical outstanding Shimano quality. Great braking control and modulation.

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.

Well made, simple, fast install

Excellent product. I feel confident when stopping. It arrived quickly.

These rotors are perfect for those not willing to cough up the extra for the SMRT900s.
