Shimano Announces New Flat Mount Disc Brake Standard For Road Bikes

yeah! another standard! yeah! why on earth do we need to move away from the mtb disc brake standard??? it has been shown to work just fine on many existing bikes currently available. bad choice shimano, very bad choice…

I guess we’ll have to wait until more info comes out, but how do you account for different size rotors?

Hum.. Let’s see by the looks of it.. It’s attached to the frame on the inside… So more chances of stripping threads when adjusting.. Also.. Once stripped… Hum frame has to be replaced… I’d say that’s planned obsolescence. Also, where’s the adjustability to use after market stuff so that your not just using shimano’s stuff… I think there’s enough said… Hope this is not another standard because shimano thinks it’s a good idea..

Derek, you use the right size rotor, there is no need for different rotor sizes on a road bike

Can we start using quote marks around “standard” when it’s just a mfr’s proprietary bullsh*t?

Leave it to Shimano to cram another “standard” down our throats and force us to use something we don’t want. Post mounts have worked great for years. There is no point to move away from mtb just for the sake of moving away from proven mtb technology. Thanks, Shimano!

Flat mount. Twin Post Mount. Who needs it. I am holding out for a super conductor mount that will allow the caliper to pivot independently. NEVER need to adjust as it will just morph to every nuance in your rotor. It will be so awesome.
Yes….I am joking. And yes…..I LOVE disc braking. My post mounts work just fine Shimano. How about you push the envelope rather than just slide it laterally.

This makes perfect sense. Since there will be little to no crossover between mountain and road brake systems, why shouldn’t road brakes have a more appropriate interface? And it’s backwards compatible so who is this likely to inconvenience? People always want to whine about new standards, would you really rather we still used square taper BBs and straight steer tubes? Gimme a break…

This is stupid, post is the way front and rear. Am I the only one that thinks a 160mm front rotor on road bike is to small?

Yeah posts mounts work just fine… blah blah blah, they also aren’t that aero, and heavier than they need to be. Sure it’s another ‘standard’ but hardly anyone has Disc equipped road bikes yet so it’s not like this is affecting many people. Shimano has proven that they make the best brakes in the industry by a clear and obvious margin, and giving them the benefit of the doubt (considering this fact) seems fair. I for one applaud the dedication to make a change BEFORE the majority own the ‘old standard’. As for ridiculous statements like “Once stripped… Hum frame has to be replaced”, that’s how it already is with post mount. They already own the road disc market (thanks to Sram’s incompetence) so how can this be viewed as a marketing ploy? if anything they are running a risk by trying something new.

I seriously hope this standard includes replaceable threads (ie threads in lateral inserts like on Turner MTB’s etc).

Also can we get a ban for Bobby @ 5:55pm, what a pathetic useless comment.

“Disc-brake calipers have always looked gawd-awful on road bikes because they look tacked on.”

And this is different from current side pull calipers how exactly?? Unless you’re in the distinct minority of people who either own one of the newer aero frames or a 50+ year old constructeur bike chances are your brake calipers are tacked on with a single mounting bolt instead of being integrated into the frame. Only difference is it’s a look we’re used to thanks to 50 years of tradition.

As for aero brakes, if you think that actually makes a difference in the real world you’re a fool. Despite 50 years of aero advancements the average speed of the Tour de France has hardly changed (and keep in mind the Tour was much longer 50 years ago and still included a lot of dirt roads!) Sure, aerodynamics come into play during time trials but even then the vast majority of the gains come from rider position and wheels. End of the day it still comes down to the rider.

Roadies just hate change; p It looks cleaner and that would be more appropriate for road bikes. Possibly aero gains. looks is half the battle! I hope to see road disc to continue to evolve; )

I was about to throw a fit until the last point of being backward compatible. Don’t say this too often, but thank you Shimano. Up to that point I only saw this as a money grab by some what forced change.

This is much bigger than Shimano introducing a new standard. In order for road disk brakes to be adopted by pro teams and the UCI there needs to be a very clearly defined standard that all frame, brake and hub manufacturers adopt to facilitate quick road side wheel changes. It makes sense that Shimano, the largest component manufacturer working with leading road bike brands, would develope the standard. There is nothing wrong with post mount brakes except every frame, brake, adaptor and hub is different, making wheel changes too time consuming for the pro tour and too difficult for neutral support.

Sigh. Road bikes don’t need disc brakes anyway.

First rule of businesses: NEVER miss an opportunity to f**k up consumers with +1 standard that does nothing, in the name of money.

Err I mean, MTBs had the position wrong ALL along this model is so REVOLUTIONARY. lol.

its going to be super sweet and everyone will want them. just you wait. l do!!

Interesting…..

backwards compatible defeats all arguments

Disk on road is not needed but amazing all the same.

Rotors should be no more than 140mm or 160mm on road. (grip is only as good as your tyres)

My guess is that mountain frames will follow.

I am bathing in irony by lamenting the constant creation of unnecessary standards and technological progression in the biking industry while driving around in a late-model BMW, and not a horse-drawn carriage.

Cyclists: An hypocritical batch of tools

please make it stop

Re : stripped threads in caliper mounts. The solution is a heli-coil kit. Not sure why is rarely mentioned. Fixed my Fox fork mounts this way. Get on it, bike ‘mechanics.’

Here a picture of the KTM bike 2015 release: http://bikeboard.at/_uploads/_fotos/66828_986849.jpg
You can see the “new” standart (so it was released by Shimano a long time ago!). KTM PM said that the new caliper are to come 2016!!!! In my option it looks ugly with old caliper and I was wondering how it looks with 160mm rotor. I will buy a road racer with disc but I will wait to get “standards” for hubs, brakes and axles.
