not even a mention on the site news, slipping STW slipping!

Psst, don't tell anyone but STW is a mountain bike site, and those are part of a road groupset 😉

On another note, really not bothered by hydraulic brakes on my road bike. Plenty of stopping power [i]and[/i] modulation with my brakes as it is. No need for anything heavier and more expensive thanks 🙂

They are not heavier.

I had a flashback to 2001 and people who were using V-brakes on mtb's when I read that.

Designed to have same stopping power in dry as a well set-up caliper brake (ie, limited by tyre grip) but they have even better modulation and work as well in the rain or dirty conditions. Why wouldnt you want that?

Looks very nice, but going to have to wait a long time before trickle down makes that affordable for the work bike! The quoted prices on Road CC were eye watering.

They will be based on avid discs so will be hugely unreliable and crap, with random lever to bar no brake power moments and numerous other issues. Best avoided until shimano etc bring something out!

That's an Interesting read actually, and a very clever move on SRAMs part to produce a hydraulic rim brake that works with the same lever as the discs, they can get a bit of staged adoption going, especially with with those looking to update brakes/drive on an old non-disc frame, levers are pricey and I think people might be looking for a bit of future proofing rather than jumping on the disc braked road/CX bike band wagon

Shimano will need to catch up and offer something comparable on DA soon, in fact DA Di2 would be ideal, as they can probably make slightly a lighter, simpler lever with just micro switches to house rather than cable shifting mechanisms and a master cylinder .

According to Bike Radar, the Hydro R disc option adds about a pound to the overall bike weight after fork/frame/wheel updates are also accounted for. I guess you might win a little of this back through eventual lighter rim developments, though there has been little evidence of that in MTB until recently. It would let you run expensive carbon rims without wear worries though.

because they are horrifically expensive, are made by Avid which ime means unreliable crap, for the purposes i use a road bike my brakes are good enough, i have no interest in buying a new bike, crashing is not an option!

and if you notice Sram are hedging their bets, they have released a hydro caliper so they aren't sure which way the market is going.

Sram electronic is on the way so whatever you buy will potentially be out of date very quickly, which means spares may be an issue.

Finally, have i ever been riding and think, you know what i could do with more braking on the road bike? no. MTB is very different, did i ever think more brakes, no, but did i think increased mud clearance, yes!!!

Didn't expect to see it on stw as they are road brakes, why would a mountain bike site feature them? plenty of info on road.cc.

Hood's a bit funny looking.

Didn't think the prices looked too bad, but then probably been desensitised to that sort of thing by the prices of other top end groupsets.

I 'd have thought that would have more to do with UCI rules. I'd imagine they'd get dropped when UCI allow discs on the road.

Good luck when you get break fade on some long mountain descent!

are they top end groupsets though? Red i would agree but Force is meant to compete with Ultegra and i guess Athena. both of which are cheaper.

Anybody know whether they're staying with 130mm hubs or going to MTB width 135s? (which will then affect chainline and BB width?)

TBH the weight argument is a bit open ended, with the reg's weight limit on competition road bikes you might as well accept heavier but functionally better drive and brake components and let frame manufacturers build the lightest frame they can to hang it all from, it'll all come in about on target for the whole bike, it's easily possible to build an underweight bike already isn't it?

I'd imagine road discs would ultimately mean silly light carbon tubular rims become more common, as well as lighter disc specific clincher profiles, wheel mass could be driven down overall, especially towards the outer circumference (where it apparently matters more).

In an ideal world we'd be heading for frames that came with integrated brake hose and electronic shifting wiring looms with a single standardized set of connectors and fittings, that won't happen, but it would be good for encouraging adoption IMO.

Are Campag even playing the Leccy shifting / hydraulic disc brakes game or will they just wait for the dust to settle and then join in?

Campag have had electronic gears being tested with the pros for about 3 years. IIRC they're just about to go to market. No word on discs or hydraulics though.

The expectation and what we've seen so far is 135mm hubs

Shocking... my bad 🙄

Haven't seen it out on the road unlike Di2 which I've seen plenty of...

And Campag saying something is going to be available isn't the same as it actually becoming available, anyway so it's a reasonable assumption 😉

Even the rim brakes aren't going to be directly compatible with current frames are they - it'll obviously need a full run of hose to the back and looking at my road frame I've just got a couple of cable stops. Will roadies want to ziptie the hose to their frames?

You can just file out the cable stops to allow a continuous cable.

I'd expect to see internal routing of the hose.

I ordered a new bike yesterday and Super Record EPS and Athena EPS where amongst the options I didn't choose (Super Record will have to do). 😉

bit like Shimano Airlines then....

As for Campag and Hydro,

[url= http://road.cc/content/image/65170-colnago-c59-disc-tricolore-paint-job ]Colnago C59[/url]

I suspect this will be the way campag approach the market, get someone else to make at least the calipers and then colaborate rather than try and create something totally in house.

Yes, if you factor in 10/11 speed, Campagnolo or Shimano/SRAM, rim brakes, 140mm rotors, 160mm rotors etc. etc. then could take a while just to find the right combination!

Pray god they don't adopt 15mm or 20mm maxles too!!!!

Shimano already have road hydro disc stuff being tested, whether it makes 2014MY release I don't know but I doubt they'll be flapping too much as discs will still take a couple of years to get a decent market share. If DA Di2 2015MY is hydraulic discs + wireless I don't think they have much to worry about from SRAM.

EPS is a LOT of money. Like £3.5k rrp. It's very nice stuff and the shifting action is lovely, but that is a LOT of money

I think if i tw*t a rear mech it is around £600!!!
A cassette is RRP £300ish!

As you say it is a LOT of money, but so sweet!

Roadie thru axle

I'm not convinced though. I still don't use thru axle offroad and there's less need for it on road IMO.

It'll be interesting to see where this goes. V-brakes were never that good really and for MTB, braking surfaces out of the mud and need for lots of reliable power at short notice meant discs were a solution to a problem.
But on my road bike my braking needs are very different - no need for so much power at such short notice. But weight does matter.
Not convinced about discs on road bikes being a solution to a problem that we really have.
On the other hand, it gives the MAMILs an excuse to spank even more ££ on kit...

discs aren't really about power though are they? as the luddites always say, you can lock up your wheels with calipers easily enough.

Using my cx bike (with discs) on the road (with road tyres) it's suprising how much better feel and confidence I have than on normal road brakes on my 'proper' road bike, particularly in slippy conditions. Not something I really expected TBH.

One thing I particularly liked about the SRAM hydros story was the barrel adjuster for the rim brakes. Neat.

Not at all, just making sure that there's a market there for existing customers - bear in mind that 99% of people won't have a disc ready frame but they might want to upgrade to hydro rim brakes. And from there you can upgrade later to hydraulic disc brakes using the same shifter unit when you buy a new frame.

This.

Those dismissing it out of hand would do well to to look at the [url= http://singletrackworld.com/forum/topic/show-me-your-cx-bikes-2 ]Show Me Your CX Bikes[/url] thread on here and consider how many of them have discs and are being used as sturdy road bikes rather than for actual CX races.

Those saying you never need to stop quickly on a road bike should try commuting through town on one with wet grimy rims.

It is an interesting development. Expensive for now - but then so were MTB hydro discs when they first arrived.

I do, on 23c tyres. I can see why some folk would like discs, but I'm not fussed, road callipers really aren't as dangerous as some seem to make out!

460g weight penalty for discs though, even before you add in hubs and heavier frame/fork. That'll be a barrier for many.

That Giant cross bike makes every other 700c look instantly dated. Roll on the SRAM groupo's and hopefully we get 10mm thru-axles from the get go.

i suggest you take some time to read the Road.cc article, SRAM are offering two options and in there words they don't know what the market is interest in.

Personnally i prefer the look of the hydro Magura's just not the price. And they use Mineral Oil which is a plus IMO.

taken from the interview with the SRAM bloke.

[url= http://road.cc/content/news/80972-why-sram-believe-hydraulic-brakes-are-future ]Road.cc[/url]

We really like the way the rim brakes ride and we’re all about choice too. We like to put a couple of good options out there to allow the customer to choose what they want.

We may find eventually that hydraulic rim brakes do win out over hydraulic disc brakes, although I don’t think that’s going to be the case. I don’t think that discs will kill the rim brake, I think we’ll see the two options, but I do think that mechanical cable-operated brakes will go away.

It's not the first time manufacturers have had a go at road hydraulics.

I've got a set of Magura drop bar hydraulic rim brakes in my shed. Had them several years.

swapping from my disc braked CX to my road bike for the first time since I got the CX I was missing the feel of the discs, and this was in the dry. I was kinda doubtful of road discs thing but whaddya know after actually trying discs on the road I guess I was wrong 🙂 Not looking to upgrade my road bike so not too fussed about road discs myself, but would like full hydro for cx in the future.

wanted some of them for my pompino

Another advantage of disc brakes tho is for trusty commuters/winter hack bikes, you aren't wearing away the rims [b]everytime[/b] you brake.

One of the reasons they're in the shed.

I did buy a set of stainless steel rims to use with them though. At 790gms they're not much heavier than heavy duty alloy rims.
