New, Beautiful, Heavy! Dura Ace RT-CL900

[@DummyUrD]

The thermal properties of the Dura-Ace is that it vaporizes your money faster.

[@SpeedBoosted911]

It's funny how stupid people are, and what I mean is: many look that lighter rotor is better(cuz it cost a lot), but actually brakes work the way that Rotor absorbs energy by heating up and it's mass, yes - mass, directly related to the temperature they get. So if you put a 50gr rotor, it'll get burned twice faster than the 100gr. Here adds up a cooling, but it's a secondary value, not primary

[@SAFABrian]

Didn't even know there were new DA rotors out. That's why I follow this channel. They do look niiice!

[@nochancecw]

I am so glad they added weight. I'm 90kg, and I destroyed the last generation Ultegra. Ive switched to MTB xtr Rt-900 and it did help a lot. I think the extra 10-20 gram saving isn't worth it with safety systems. Safety systems like disc rotors should compromise a bit to be more reliable. Thanks for the video.

[@paulschectman6586]

That roadway is insanely perfect. I have never ridden on a road surface that smooth.

[@romanpramuka2703]

A few days ago I've installed Galfer wave road rotors, replacing my MT800 rotors. They are 10g lighter at each size. After few rides with also new pads, they perform perfectly, maybe even a bit better. One big difference is, after heavy breaking when they become hot, they don't start ticking like with Shimano, when you need to wait for cooling down. For me 👍 Galfer rotors.

[@NickPavlenko]

Switched to Galfer pads (road specific) and also very happy with the modulation and fading properties.

[@siupongwulau9315]

I agree with u 100%. In my opinion Galfer are the best disc.

[@dgianstefani5694]

You want more weight in your discs, gives thermal buffer, preventing overheating and therefore warping. It's physically impossible to have a disc that's ultra light that won't overheat from braking and deform eventually.

About the lock rings - the external type is more bulky and this can cause issues with some forks that have limited clearance. Usually where the fork bulges to accommodate the mounting hardware for the caliper.

I had the Shimano Dura Ace calipers, but found them just so so. I swapped to Hope RX4 calipers with ceramic pads using XTR rotors and these are the best brakes I have ever used. They are silent, work just as well in the wet and lighter than Dura Ace

[@rasmuswi]

They are an absolute pain to set up, though. The pads tend to end up within a hairs width from the rotor, which makes centering a total nightmare. But I agree that they bite like crazy, and once they are properly centered they are of course dead silent.

[@darrenhitchcox6345]

@@rasmuswi I am using Di2 GRX levers, so the pads are just a bit further back, so I have not had the centering issues as bad. Bleeding them is an utter pain compared to Shimano, but once done....wow

I am not against disc brakes in fact if I buy a new bike I would prefer one with those however I really can not find any fault with my usual rim brakes either even on long and fast descends. If you are an average rider, know what you are doing and have good pads like a pair of swissstops rim brakes are perfectly okay at least for aluminium wheels.

Looks like from the packaging these new CL 900 rotors don't come in a 180mm size. I use a 180mm up front on my road bike with the Peak Torque Adapter and a 140mm in the back. Perfect balance stopping power. Weight isn't a factor for me, performance is. I also like the MTX Red Label ceramic pads better than the Shimano pads.

Not light but apparently the braking surface is all stainless steel . Not a sandwich of stainless/alloy/stainless like Shimano

[@ridesofjapan]

My impressions are pretty useless as I’m not really a power user, definitely check GPlama and The rainmaker for all the details. All I can say is I looooooove the battery life, it’s insane how good it is taking into account all the functionality. The solar charging is a sweet bonus. I always hated the touchscreen garmins in the past but this has not given me any issues this far. I still wish they would put buttons at least for changing screens but, I’m pleasantly surprised with the touch screen. It is humongous though, and if they make a 540/840 with same battery life I would probably sell the 1040 and switch to that.

They didn’t, you can get them with either version. The internal (cassette tool variant) is probably the version that you’ll find in most stores. I just didn’t pay attention when I got mine. The external rings are used on some hubs (15mm true axles hubs for example) that can’t take the internal one.
