Would someone please explain direct mount brakes?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Would someone please explain direct mount brakes?

Taking the Planet X example, as they are almost my LBS, they are not a little guy (not Trek big, but not a small player either), cost for developing new product mounts will be the same as any other product, no manufacture will be putting direct mounts on their current models, only on new models, (would count the Trek Emonda as a new model being as it only came out last year).

You could look at the direct mount brake in the same way as disc tabs for MTB's back in the late 90's, in 1997 very few bikes/forks had them, come 2001/2 a bike without them would be a negative selling factor, and at the end of it, bike/component manufactures are in the business to make money, if consumers want the direct brake, bikes will be fitted with them.

I hear you, but we are talking at cross purposes. I'm not talking about frames that will accept the new brakes or whether major component manufacturers will offer them. Those guys have OEM contracts that will support the development. I am talking about Ciamillo, KCNC, etc. I don't know who makes the CNC brakes that Planet X sells under their own name, but that would be another example. Those guys will fall behind at least a little trying to bring out their own examples of the direct mount type. Taking Ciamillo's cam brake for example, I'm not sure if that can be adapted to the direct mount concept. That is what I am talking about.

Really can't see this happening, as I already mentioned, it gives these smaller (and would only count Ciamillo as being small, or rather tiny, KCNC has been around a long time and isn't a small player either) a chance to innovate, add SKU's and increase sales with these new SKU's. Looking at other manufactures, take Paul who's brakes are in photos earlier in this thread, they have had products come (shifter adapters, light mounts) and go (RHUBS hub), and are still going.

For the Ciamillo cam brake adapting to direct mount, does it really matter it if can be, again, its an opportunity for aftermarket manufactures to bring new designs and ideas, it's not as if the current single bolt brake mount is going anywhere, Even if all bike produced from tomorrow had direct mounts, that still leaves all the bikes produced to today with the single bolt which would be fitted with the single bolt design.

In addition specifically for Ciamillo, having had a look at their site, given the volume of rakes they produce, they are so boutique/limited in production numbers/volume that they probably don't have capacity to introduce many additional lines, so till their current products stop selling, there would be limited/no need to look at replacing their current line.

Is there anything truly NEW in the bike world?
well, in defense of the new brakes, the elimination of the straddle wire and hanger is improvement enough, in my book. not that i have found need of it for quite a while. braking improvement, that is.

My 2015 Giant Propel Advanced Pro 1 uses proprietary Giant direct mount brakes. The front is mounted behind the fork from on studs. The rear is also on frame studs. One of the nice things about them is the thin aero profile.

I'm not sure why the center pull brakes fell out of favor.
On the front, I don't like the stem bracket and slotted stem. The bike I put a front center pull on seems to have just a little too much flex in the whole system.

I've got a bike that was setup for canti brakes with the wire that I'm going to try to convert to center pull on the rear shortly, if everything fits.

So has anyone put any miles on these brakes yet? How do they perform?

My 2014 Jamis Xenith Race has it on the rear. The way I understand it, at least for the rear one, is that it allows for less rigid seat stays (no cross bar and not needed extra strength) for a more compliant ride. The higher-end Xenith has it in the front too, on the back of the fork for better aerodynamics.

I have just the rear on my 2014 Jamis Xenith. I have ridden over 3k miles with no issues.

Do anyone know about v-brakes to direct-mount calipers bridge/adapter/converter? was offered a carbon frame for a very good price because company roll out new version. But this frame accepts only rear V-brake mounted under bottom bracket. The modulation is more important for me than stopping power.

Hi, if you have a new question, open a new thread, not reply to a 3 year old one, which has little to no relevance to it.

For your question, as you don't appear to have purchased the frame yet, don't, either get one which has the spec you want, or live the the spec it has, and learn to use the brakes type as spec'd

He asked the question five days before you lectured him.

Well, I'm sorry; I only got the weekly e-mail notification yesterday. This is a necro thread, and it's bad form in any forum updating a thread like this, especially when the new post has nothing much to do with the original post.

For your accusation of lecturing, I did nothing of the sort, If I had been 'lecturing' I wouldn't have started with a pleasantry - Hi

BTW your response was useless, you could at least have had a suggestion to add to the new poster.

For you, I heard you. I just don’t care.

Why not make a statement and rock the original direct mount brakes (cantilevers notwithstanding):

If the tire is pumped. If flat, they tend to come right out.

It's the "in" part that gets ya. I've got a Propel. I doubt it would be as much an issue the less tire you run as a ratio to your rim width though.

Is there anything truly NEW in the bike world?
The one thing that can be said for modern brakes, direct mount, disc, roller cam; is that they finally match the performance of 60 year old post mounted center pulls. Match these with aero levers and you have enough stopping power to lift your rear wheel a foot off the ground (If you ever experience this life awakening event the good news is you can still steer the bike like normal. Just try not to panic, too much. Concentrate on not hitting whatever it is that's causing you to brake so darn much.)

Didn't read the whole thread, but the first few posts were talking about saving material.

Pretty sure that's not the point. The point is rigidity.
