New Dura Ace disc brakes, will they rub?

- So Shimano touted the new Dura Ace 9270 disc brakes as a big improvement, with better pad clearance and all that jazz. With properly set up brakes I didn't really experience much problems with the previous model but I though I would at least measure and see if that increase in pad clearance actually exist, and give them some heat downhill to see if I can get them to rub.

Corrections Corner: I said the brake pads was J03A in the video which is incorrect, the pads are the L03A. Same pads as previous gen DA, Ultegra and GRX etc.
Thanks @dxdbstrd for picking that up!
Back to the roots of this channel with a descent video 😄
What an amazing road. I wish I had roads like this where I live.
Sadamine Toge is a great ride, Use to do Hanno /Chichibu/ Sadamine/ Ogose/ Saitama Idai/ Hidaka then home, Some nice quick straights too. The cicadas are so nostalgic.
Hi Sir, please give us endless descending roads in videos like this one. Keep your comments as well during descent :D
Amazing footage and stabilization!
We need more of these just riding videos
Amazing descent. After watching your videos, Japan is definitely on my cycling bucket list.
Great descent, great descending -- pleasure to watch your lines.
It's always a good Sunday with ROJ!
Stumbled across your videos a few weeks back. Love your videos dude, amazing production quality, funny, interesting and clearly know your shit! Deserve every follow!
That intro is awesome (visuals) and hilarious voiceover. More please.
love the opening music, great video & love the autumn colours.
stay safe.
Sunday lunch followed by a cup of tea and rides of Japan!!! Perfect!!!!😁👌👏🏻
Beautiful atmospheric riding footage. Just loved it...
Honestly I could just watch the riding video all day, really miss Japan and those roads
This first person camera postion is so good, I could watch this all day!
Great to see you riding in a video again 👍😁
As usual, some of the best intros in the business!
Plus, the rest of the video is not too shabby. 🤣
Great video, really enjoyed watching that and looks like a good improvement on the brakes if no rubbing.
Those roads look lovely, what a beautiful county. Very jealous, wish I had roads like that to ride.
Got the sniffles just watching that long cool descent. Very beautiful road. All your info is interesting in a very practical way and disc brake rub was something that concerned me when I decided to put the Ultegra discs on my new titanium road bike. Still maybe too early to tell at 500km in, but so far absolutely no rubbing and very smooth operation. I may have the best combination of a very stiff frame and my lightweight 62kg.
Nice vlog and great scenery.👍
lol that intro was great - I love this channel
Got mine 9200 parts today! Shifters and calipers installed and I got to say that I never done such a clean brake bleed like today. Separate allen key is definitely a great feature.
Went for a quick ride and felt similar to the previous Dura-Ace but cant wait for the weekend!!
truly enjoyable type of stuff! please more descents Rafa style)
damn that japan sunset looks so pretty!!! nice ride!!
It’s amazing riding here and also other parts of Asia! Good to see ya on the channel!
I could watch that riding all day!
Loved the descent.
Quality work
this video was extremely relaxing
I did get rubbing issues when the rotors heated up when I installed my Dura-Ace 9100 brakes but I kept cleaning the pistons and working some mineral oil around the edges and that finally stopped. For the last few months I have not had any brake rub noise. Adding more clearance to the pads wouldn't make a difference if the pistons are not retracting as they are meant to do. The way you descended that road SAFA Brian would be proud.
Great descent 🙏
nice descend! 🤩🤩🤩
beautiful road
Wow beautiful! I just moved to disc breaks(ultegra) and getting some rubbing and screaching! Much to learn...
Get used to it. Even the best mechanic in the world can't stop disc brake screeching. Just watch any cyclocross race. Organizers should be handing out earplugs to the speculators beacause the disc brake screeching is so loud.
@@stephenchu1115 Starting to think rim brakes were just fine!
Rumour has it that other chap is still descending...
Liked the 21:9 intro! And chest cam was good. GoPro?
He was flying! 😂
Camera is a DJI Pocket 2.
No GoPro (or other digitally stabilized action camera) can handle that kind of low-light conditions when you want some motion blur.
@@ridesofjapan Looked very good!
Everytime i had disc rub it was with rotors going untrue. Since i moved away from various shimano ones to the hope floating rotors i never had a problem again. those things just work.
i also have a pair of extra thick (2.2mm) ones on my gravel bike from intend b.c. - those pretty much always rub when they get wet because the clearance in the calipers itself is so minimal that any small dust particles hit the calipers. its a bit annoying but i like those discs for added ease of mind when traveling with the bike and wheels off. due to the one piece thickness they are very resistent to bending and also takef all of the heat i could throw into them on a loaded steel gravel/touring bike descent.
btw beautiful descent you have there :)
The music and Japanese scenery were beautiful. Would love to see some more footage and commentary of your rides.
Lovely weather
Great review. I really like the way you were able to measure the pad clearance difference between old and new. Smart!
What a beautiful ride. Like so many in Japan. Cheers, Mate
What a beautiful place.
Mounts flats, calipers straight and rotors true. Magic recipe for a noiseless ride
✅✅✅
It’s not rocket surgery… Anyone who has problems with disc rub just doesn’t know how to set them up.
Great intro xD
I miss mountain rides in Japan. Challenging and peaceful. Rarely another living soul to be encountered. Japan has some of the best riding in the world. Paved river trails along many of the rivers and many unused but maintained mountain passes.
MAAP and Black Sheep double. Australia in Japan. Awesome!!
Please post more of these descent videos, Japan looks so pretty. You could do what Safa does and do riding vids in HD
Nice descent
I am a bit heftier than you at 90kg and had it rub on my 5800 105's but only on descents after braking. It was a ting ting ting till they cooled down. I would love to see a 105 trickle down for the extra pad clearance.
Great video! You should display the speed on the descents next time.
Here in Japan, people are more unforgiving to those who do not abide by laws, even for just exceeding legal speed limit by 10-20km/h. This is especially true when one posts his/her "incriminating" evidence on social media.
I, too would love to see all the metrics on display, but I rather RoJ gets to keep posting more interesting content than getting banned (or worse!).
I've just upgraded to Ultegra 8170 from 8070. I did occasionally get rubbing when putting a lot of torque into the frame (I'm 1.88m and 90kg), but I haven't noticed any rubbing with the new brakes.
Hey does what you said still hold true? I have 105 and I've had so many problems with rubbing. I'm getting a custom frame for my abominable proportions and I frankly I'd rather get 105 again but if the brakes on r8100 are genuinely better then I'll pay the price.
@@crimson177 months later, I can tell you that I get occasional rubs, when launching into a sprint or powering out of a bend. Still much better than 105 though.
A lot improvement on new 9200 the rotors compared 9100 rotors I got issues decent brakes a lot noise. Used Dura ace 9100 rotors.
Ok, I guess this vlog _is_ about the change in clearance on the new Dura Ace disk brakes, but... I think that by just putting that as the title you might be putting a limit on how many people [that get the exhilarating joy the speed and the adrenaline rush of descending on a bike can give you] get to enjoy the pleasure of doing a spectacular Japanese mountain road descent with you virtually.
It really is terrific, those roads are perfect for that, those brakes are good, and so are you (man, I wouldn't want to "take unnecessary risks" as you say either, but on many of those corners I would have no option but to encroach on the other lane, and then some...) 🙏 ROJ
ps. I would have loved to see the face on that other cyclist when you went past
I don’t like this world we live in where everything is served up in the first 5seconds for the casuals, I keep the good stuff for the real peeps ;)
Jokes aside, I appreciate kind words mate, cheers!🙏
I guess I kind of suspected that might be how you felt about it. Very grown-up of you, kudos. 😅
So entertaining
I miss autumn so much.
thy all seem to rub till shoed in right. just watched your video I changed my mined them breaks look cool
Hope you can review the new ultegra side by side with dura ace.
Yes
Would love to visit Japan some day
Hey, I realy realy love your Videos! Can you give me some infos about your equipment? Especially your camera setup and cutting software? That would be great.
Thx and greetings from Germany
Sony a7s3, DJI pocket 2, Final Cut Pro X
Cheers!
Interested in your experience of the brakes in the wet……this is the litmus test for me…….. anyway great vid as always 👏
That I will never find out if I can help it ;)
@@ridesofjapan ha ha……sadly unavoidable in the UK unless you only Zwift 😀
@@ridesofjapan Yes. 90%+ of the road riders on these fancy racing bikes with hydro disc brakes with integrated cables don't ride in the rain with that bike - thus negating the only advantage of disc brakes over rim brakes on road bikes. In the dry, rim brakes stop just as well as disc brakes. So really there is no point in disc brakes on road bikes because there is no advantage for normal "joes" who don't ride in the rain with the obvious disadvantages - heavier, cost more, less aero, maintenance nightmare.
Extra gap means you can run a thicker rotor, which could good for the summer time.
Awesome Footage! Question: what's the blue jersey/jacket you are wearing (?) - would love to get me one of those.
It’s an old black sheep jacket, LTD from a few seasons ago.
@@ridesofjapan Cool - thanks for the reply! if I cannot get my bike as light or be as pro, I can at least try'n look the part :D
What's your opinion about the whole disc vs rim debate ? I'm enjoying your videos way more since you added the descents
What's the name of the little floofy clip-on microphone you're using? Sounds great!
It’s the wireless mic for the DJI pocket 2
What kind of camera gear are you using? Footage looks great, especially for low light 👍
DJI pocket2
what is the blue jacket? looks nice
Japanese roads look great!
Any thoughts on brake feel? Is it the same as with the previous ones? Any idea if you can use old shifters with those new calipers?
Before 9270 I was exclusively riding GRX for a month or two which also has servo wave tech, they feel very similar to that. But I wouldn’t say it’s a huge difference for the old DA… nothing I need “adjusting” to but the lever is super light until the pads hit the rotor, from there you could argue there is better modulation, but noting that will totally change how you brake or anything.
You can connect the calipers for sure since they use the same hoses, but if they require a lever with servo wave or not for proper operation I can’t say.
@@ridesofjapan according to the Shimano compatibility info, they are compatible :)
What @@BetterShifting said ;)
I dont hear any flopping noise front the levers either… my sram levers rattle like crazy if my fingers are not putting pressure on them.
You descend quicker than i'd go on some of those hair pin turns.
Hi,
How do you find the 12 speed chain and cassette working with your 11 speed chainrings? I’m trying to work out if I could use my sisl2 cranks and cannondale spiderrings with the 12 speed kit. Any help would be appreciated. Keep up the good work👍👍👍
Shimano 12speed chains has been used by a lot of people with 11speed chainrings for a long time with no issues. I would guess that goes for the sisl2 as well, but I have not tried myself so can’t guarantee anything.
@@ridesofjapan Thanks, to order with or without the 12speed crankset 🧐 that is the question 😂 #firstworldproblems
In conclusion one has to get a really good pair of brake callipers somewhere in the likes of a shimano ultegra or dura ace, anythingk lower than that will surely suffer from an occasional brake rubbing sound and drag
about the descent…the traffic being a real challenge here… 😅
That unassuming "こんちはー" as you overtook the cyclist ;)
Have you done a video before about yourself and how you come to live and work in Japan?
Your video's are great and I like the scenario that you show on your rides.
Sorry I don’t really share anything personal apart from the bike Shenanigans (it’s boring anyway 😬)
Cheers!
@@ridesofjapan - Totally Cool with that.
Sandamine Toge always scares me on the tight corners with cars climbing fast D:
I wonder if using Magura calipers would be the solution. These work with a magnetic return and supposably have a bigger clearance. They also use mineral oil so no issues with compatability with the Dura Ace system
But they are still not designed for the dura ace system. Sure shigura setups work, but not as intended. Especially now that the new generation has servo wave.
RoJ, probably the only cycling CZcamsr Joe of Winspace has not been able to penetrate! 🤣
Fight the power ✊
(Jokes aside I have nothing against winspace, but the over saturation is real 😜)
@@ridesofjapan indeed. I too have nothing against them but as you said it’s over saturated. My local bike stores have them, it’s on every cycling CZcamsr there possibly is, even my local secondhand market has them 😂 they took it to another level when they paid GCN!
I really hope this brake pad clearance is the same with Ultegra
What did you use to push the pistons back ? Is it a true lever? Do you mind tell the brand if so
It's an IRC "Tubeless" tire lever.
nice cycling cap! what brand is that?
Peloton de Paris
Gracias!
Hi, so J03A brakepads fits on 9170 caliper? I though it was L03A that comes as a kit, which is expensive and rare...
Oh crap, my bad! it’s the L03A pads (same on both 9170, 9270, 8070, 8170 GRX etc..)
@@ridesofjapan thank you!
Hi there! If I may give you any advice: When cornering right, stay on the left side (vice versa) a little longer, that way you stay in your lane better and exit faster. Cheers!
could you compare this to the pad clearance on GRX and see if that is comparable? Th GRX brakes are pretty solid and seem like they have good clearance.
I don’t have the GRX calipers, but they are the same as the regular Ultegra level calipers. The difference on GRX is in the lever (di2 levers) which use the servo wave technology that they also use on the new dura ace and Ultegra 12speed levers, so they “feel” very similar in that way.
With the increased gap was there a difference in pressure or lever pull required?
The new levers have the “servo wave” technology, so they feel closer to the GRX di2 lever than the old dura ace (that’s a good thing)
✌🏻
Is that new bar tape? Looks like the Fizik Vento
Some 2mm fizik tape... my favorite tape was sold out everywhere
right - more questions (I hope you see this one, as i am curious): You have been using the Panaracer Gravelking Slicks afair. What's your verdict in terms of slipping & grip on wet roads? I am concerned of not having enough traction and risking an accident..
First, I’m a fair weather cyclist, and the few times I’ve been out in the wet I always take it very easy and don’t push my equipment anywhere near any their limits.
With that said since I only used GK slicks 32 and larger in the last couple of years and I always run very low pressures and never felt a lack of grip compared to any other tire I’ve used. But again always dial it back when conditions are sketchy, I’m not racing anyone so :)
@@ridesofjapan Lovely - thanks! I try not to ride in the rain either (too much hassle in terms of cleaning) and do not race. I was looking into the 32mm version (not tubeless yet) and will not go for risky stuff anyways. So I will defo try them asap
Hi, I have to change my 105 disc rotors and would like to use the ones you have. What's the exact model? Xtr if I've catched it correctly?
Shimano MT900 rotors
Don’t like how I need to buy a whole new bike just to get disc brakes, my rim brake bike is still going strong! But wouldn’t mind the better stopping power of disc brakes
How was the intro of this vid shot? What equipment was used?
Dji Pocket 2
XTR's rotor as good as Hope's rotor?
if I remember correctly you never had a power meter on any of your bikes. you mind sharing the reason/thinking process, perhaps in a coming vid? thx
It's pretty simple, I ride outside for fun, not for fitness/training. (Might very well get a power meter in the future though, but it's not topping of my list of priorities)
@@ridesofjapan ha, ok! please teach us how to do that!! The last bike I purchased was based on the BB standard because the power meter I wanted to install came with a 30mm spindle (rotor 2inpower) so the bike had to use a BB386Evo standard. Riding long distances has to be in my endurance zone, no coasting allowed whatsoever. I think I need help :)
Footage looks 👨🏻🍳😘 using a new gopro 10?
God no! wouldn't have been able so see shit with a gopro ;)
@@ridesofjapan kinda wanna know what youre using for the chest rig then ;)
