Road bikes with disk brakes

So far the only high end road bikes with disk brakes are the specialized roubiax and the colnago c59. Are there others? My Google fu is failing me right now.

I want to build up a da di2 road bike with disk brakes and it looks like shimano is about to release the r785 brake lever to do just that.

My other question is, I have several sets of zipp aluminum track rims that I am considering having a Chris king disk hub put in, is it that simple or does something else need to be done to the rim, or should I look at rims that were designed for disk brakes?

is this for cyclocross . I like the look of there bikes. I don’t think they do cyclocross here in australia

No a road bike, not a cyclocross bike.

Thanks.

racing, training, or commuting?

hydraulic rim brakes might get you the better braking you want, and then your options will include all bikes.

Cannondale has launched a new line of Synapse road bikes with disc brakes.

Training/racing.

I was looking at SRAMs hydraulic brakes, but wanted to give disk brakes a go.

But at this point if road bikes are having disk brakes added to them, is there any difference between a cross bike and a road bike with disk brakes?

mid range would get you a BMC GF02Disc
.

The geometry of the frame is different between a road and a cross bike. Cross bikes have a higher bottom bracket and higher top tube…

If you are primarily going to ride road…you may want a road geometry

although I’m not really sure what the draw is, if you are racing good luck with neutral support!

Pretty sure Volagi’s all have discs, but they’re geared toward endurance riding. If you want a real expensive bike, Moots makes a Vamoots with discs now. I know there are bunch more, but they aren’t coming to mind right now.

Majority of the big names have made a disc road bike. Just google: http://www.google.com.hk/search?hl=zh-CN&q="disc%20road"&gbv=2&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi

Many are not really convinced it’s necessary, but it’s a marketing disaster to be perceived as behind the curve.

Ran into a gentleman at Interbike this year (taking a shuttle from Excalibur) who had half a thumb chopped off by disc rotor…

Just fyi, a disc brake setup typically adds about 100grams of drag, so it is sort of like going negative on the speed to the same degree a scott foil/r5/madone semi aero frame goes positive on the speed. Maybe more since that 100g of drag came from a company pushing the idea of disc tri bikes.

Give a SRAM hydraulic or Maguaru hydraulic rim bike a try, it is really very very nice and you might not see the need for a disc system after experiencing it.

If I could afford it, I would love a road bike with disc brakes for steep hill training. The descents on the hills I climb are not safe to rip down. Generally residential areas where the speed limit is 15-20 mph and cars potentially pulling in an out of driveways. Going up is perfectly fine, but down is a different story when the grades hit 10-15%.

Are you telling me that you can’t safely stop from 15-20 mph when going down a 10% grade on rim brakes? Puh-leeze… :-/

I love my maguras on my p5, and I just saw they have a convertor to use them with wired levers, just wondering if they would be as flood with the converter as they are native.

I’m getting pretty annoyed with this issue. It’s almost as if the Velonews staff is being evaluated on how strongly they advocate for disc brakes on the road. I’ve got no problem with their existence or use, but damn, they’re not the second coming. Currently they seem to create more issues than they address, and IMO, they address very very few issues. Really only one, maybe one and a half as far as I can tell…. heat management on carbon rims, riding on wheels which are out of true.

They may in fact provide slightly improved modulation and “feel” (highly subjective IMO), but in doing so they seem to come with their own baggage: weight, aerodynamics, cost, wheel compatibility (neutral support), noise (not really much of an issue IMO), and frame spacing to name a few.

I’m all for the technology, it’s great that the industry is pursuing it, but damn, ease up on the hype! It’s almost being presented as if discs are better by definition.

I’ve got mechanical discs on my cross/gravel bike which I find OK, but I have had issues with fade and wear. Based on my understanding of the differences between mechanical and hydro brakes as well as the reviews of the new road hydros, I’m willing to accept that the shortcomings I’ve experienced are likely not present in the new hydros. I actually look forward to a potential upgrade in the future.

Yup…not just VN, but Mr. Huang at BikeRadar as well…and, it looks like our own Mr. Kopecky is getting on board that train after his trip to Hawaii…

I get it that there are certain applications and/or conditions where disc braking is “the bee’s knees”…but damn, I’m sick of people glossing over the drawbacks in areas of bicycle performance that actually matter to a much greater extent than braking…or even mass. Road bikes are the way they are because of a unique “use case”…you have fractional hp engines and the attendant small contact patches that are necessary if you want the vehicle to go fast with that small hp. I almost get the feeling that these guys have spent so much time riding around with light carbon rims (and the less than stellar braking that goes along with it) that they either don’t remember what it’s like to brake with a good rim setup, or are so blinded by the thought that wheel mass is so important to performance, that they can’t imagine that it might actually be better to just add a small bit of mass to the wheel (with a metal braking surface) and keep the good aero, than it would be to go down the path of adding discs along with not only the extra mass, but all the other drawbacks as well (less aero, worried about QR skewers - thru axle? really?)

At Interbike this year I made a specific attempt to ride the Shimano and SRAM road disc offerings, along with the SRAM Hydro Rim…and threw in a jaunt on a mechanical DA group as well. I specifically tried to approach it as objectively as possible…but, to be honest, I didn’t understand all the hype. There were people riding the same disc braked bikes next to me literally shouting “Aren’t these things awesome!” while I was trying them out and thinking “What am I missing?” If anything, I found the rear discs to be almost TOO easy to lock up in a “panic stop” sort of situation…and thus predict that a LOT of folks are going to be hitting the pavement in wet conditions if road discs become prevalent.

It’s funny…I bombed down a local 3 mile, twisty, 8% ave. grade descent yesterday on my lunch ride. My bike was equipped with simple single pivot Cane Creek calipers with KoolStop Salmon pads, operated by SRAM Red levers and braking on Zipp 101s. As I did so, I took note of how hard and often I braked…along with whether or not I had adequate “modulation”…and I have to say, I can’t imagine how anything else I could use would have made it any more enjoyable, any faster, or any less fatiguing.

But, maybe that’s just me :-/

I heard the same arguments about single pivot brakes vs. dual-pivots, canti’s vs. v-brakes and then v-brakes against discs.

The reality is that we are in the infancy of disc brakes on the road. The key point in development was the hydraulic brifter. Until then, everything was just taking MTB technology and slapping it on a road bike.

Now that hydraulic brifters are available, product progress can continue. Are their rent hydraulic offerings from SRAM and Shimano the final answer? Not too likely…but they are a critical step in the development process.

Are they here to stay? Dunno…some significant hurdles to overcome, especially as it pertains to aero. Personally, I’ve never thought they would become the standard, at least when it comes to a racing bike. But I do think thee is a decent size chunk of the market that are open to road discs.

Ok you’re exactly who I want to talk to then since you have ridden all three types.

Were the sram hydraulic rim any better than standard? Or did they just feel like regular brakes? Where you able to take them out on some steep descents or were you just cruising around a parking lot?

Have you ridden maguras before? Any chance you have ridden them with the converter, the rt8c, I love my maguras and would out them on my road bike, but the converter is just ugly and I’m sure they don’t have the same feel as the native non converted maguras.

Side note - I can’t decide if having Andy Schleck being the spokesperson at the press camp for the Shimano hydraulics is marketing brilliance or stupidity.
