Disc brake-equipped bikes enter professional peloton

Team Roompot is the first to use disc brakes in pro road racing

Team Roompot is using disc brake-equipped road bikes in the Eneco Tour that’s currently taking place in the Netherlands and Belgium. This is the first time that disc brakes have been used by professional road racers.

The Dutch Pro Continental team Tweeted this photo (above) earlier today. It’s not the best picture but they’re SRAM’s hydraulic disc brakes fitted to Roompot’s Isaac bikes.

World cycle sport’s governing body the UCI confirmed back in April that hydraulic disc brakes would make their first appearance in the professional peloton this year under an experimental programme ahead of an anticipated full roll-out in 2017.

"The aim is to eventually introduce disc brakes to all levels of road cycling," said the UCI and the World Federation of Sporting Goods Industries (WFSGI).

They announced that the process would start during August and September when all teams would be able to use bikes with disc brakes during two events.

That time has now arrived and it’ll be interesting to see how things develop from here. Although Team Roompot and Isaac appear to have jumped at the opportunity to use disc brakes in pro road racing, Trek didn’t seem particularly eager to provide their Trek Factory Racing riders with this technology when we visited them back in June. In fact, they seemed to be decidedly lukewarm on the subject.

Time will tell. We’ll keep our eyes open for more developments.

What do you reckon? Are disc brakes a welcome addition to road racing? Let us know what you think.

The only time I'd want them is when it is wet but I could just switch out my carbons to aluminums and reduce my PSI. I'm not sold on the need but I am on the convenience.

Was quite surprised campag have gone with brembo when formula have been making disc brakes for mtb for years and are not far from campag

Will have to wait and see what they come up with

I personally dont think there ever will be one standard when it comes to disc brakes and bolt thu axles just look at bb's or seatposts for example

some manufacturers favour 140mm discs some 160mm, some prefer qr others 15/12/10mm thru axles

I know one manufacturer who says their frames wont come with a thru axle on the rear as the rear end of their frame is stiff enough as it is and it would be pointless

Im pro disc but couldn't care less if the pro peleton adopt them or not

Disc brakes work for me in the conditions i ride in and in the areas i ride in, they have saved me more than once when i know rim brakes wouldn't have stopped me in time (almost high sided a cow!!!!)

Once you have tried discs for a serious amount of mileage in all weathers then go back to calipers you realise just how good they are

My bike uses 6 bolt disc brakes with qr hubs front and back, ive tried my hardest to cause disc rub with no luck, out of the saddle, pulling the bars etc...

Even when removing the wheel to fix a puncture i just remember how many times i turned the skewer to release the wheel and do it back up the same amount and get no disc rub

Some people will be always against them, let disc brakes prove themselves in pro racing and if they don't then the nay sayers can say i told you so lol

As with any new technology (well new to road bikes anyway) things will improve, get refined and made even better

Now it seems that the Flat Mount and 142mm bolt thru are the standards being pushed forward there should be some interesting things to come in the years ahead.

Campagnolo will definitely have something up their sleeves, it's naive to think the opposite, I'd hazard a guess they'll have been working with Formula to get something ready.

Having discs on my commuter I can safely say I prefer them, guaranteed consistant functionality in all weathers and can't wait to get my new road bike with hydro discs later this year. The thought of having lighter carbon rims with no heavy braking surface to delaminate is an exciting one.

Go tubular. That's where you save rim weight.

been told it is Brembo but anyway, makes more sense for Campag to buy the technology than to develop from scratch.

I have nothing against disc brakes only those that insist that they are the miracle solution to braking in the wet as if a dry braking surface somehow enhances the contact between tyre and road. A slippery road is a slippery road.

I've dealt with braking in the wet without incident for 35 years now by braking earlier and by not going out in the wet.  4

Also - and I realise that opinions differ on this - I think disc brakes look very ugly and clunky. If the pros need them fine but I'll choose the equivalent of an E Type Jaguar over a Range Rover every time.

Don't get me started on Campag V Shimano. I've bollocked Campag for making black brakes in recent years. Very vulgar.

I think Ali rims versus carbon in the peloton is more of an issue, disks will give carbon the breaking it needs but at what cost, wheel change unlikely full bike change yes, but how many bikes can a team support car really carry. Does disk really give you an edge against a well set up ally rimmed wheel. I put Swiss Stop blues on my ally rimmed carbon C50's massive improvement.

Certain people just come across as being so desperate for disc brakes to be fundamentally flawed in some way and the excuses for not liking them are wearing thinner than a carbon rim with rim brakes! I'll leave it to the white heat of actual racing to decide if the things provide an advantage to certain riders in certain conditions and that is still only a relevant test for racing not the road riding that most of us indulge in.

They're here, they work, get over it.

Not a great analogy given carbon rim wear rate is very ,very slow and certainly slower than Aluminum!

But I agree that disc brakes have the potential to vastly improve braking esp in poor conditions, having used them on mountain bikes for some time.

I think the introduction of disc in the pro peloton is an unstoppable train and always was. It doesn't matter what you think about them, in 3 or 4 years from now you will only disc brakes and a common standard.

Personally, i have discs on 2 of my 3 road bikes and i love them to point where my caliper bike is now my turbo trainer bike and never sees tarmac. Discs are so much better for me, particularly in the wet. You can leave your braking, particularly on the front, so much later going into corners and it's where j usually ambush my caliper mates and drop 'em.

If I, as a complete bonehead amateur, can modulate my (disc) braking to co-exist with my predominantly rim-braked buddies when out on a road ride completely incident-free.

To suggest that professionals cannot do the same is demeaning and disingenuous: I ride to the conditions, my skill level and the skill level of those around me - once we're in close proximity then we all have to trust each other to do the right thing in terms of steering and braking.

Sure the pros are probably riding closer together and definitely riding faster but that's exactly because they are pros - and I'm not.

I don't think anybody said that they couldn't do it, in a racing situation those with discs will be maximising the benefit of those discs. They aren't on a club ride...

The point is that the "received wisdom" is that it will somehow cause crashes by the differentiation in braking performance - only if the riders are all gung-ho nobbers (rather than professionals).

Disc brakes work in CX because you have a 2-3 bike scenario for each rider. The only way to currently do a problem free swap out if you puncture is to do a whole bike swap. Can you see every team deploying 2-3 bikes per rider in the caravan? No. This is why it won't work until you can change a wheel on anyone's team bike in 5-15 seconds with no issue. *walks off*

Well, I can only speak from personal experience, but having used disc brakes and caliper brakes, and racing cyclocross and mountain bikes and road bikes and having raced in the UK and Spain and Belgium and Holland, and having ridden bikes for 30 years, I can't see that it will make any great difference to riding a bike.

Your mileage may vary, as people say...

@bikejon

You make a good point.

If the wheel is swapped like for like then there is no issue. This is where standardisation could assist.

If the hub changes the disc caliper position over the rotor centre needs resetting, due to small lateral differences on the rotor mount

Meh.

It's not a revolution, it's just a different way of slowing a bike down. It has been amazingly over-done on the internet but will cause very little in the way of actual change when it comes to riding a bike.

Crikey, I'm really impressed that you are in a position to be able to say that something wont have much of an impact on the professional peleton, what inside info do you have to be able to make such a confident and knowledgeable statement?

Speaking of neutral service...pity the poor mechanic trying to deal with a rubbing rotor when leaning out the side of a team car. How on earth is he supposed to do this? It takes me minutes to get mine right in a proper bike stand after swapping wheels.

I'm all for discs in other applications - commuting, winter training bikes, sportives but for me it doesn't work in the pro peloton due to the above. So I'm interested to see what happens (probably complete bike swaps).

Sounds like you need to employ some thin spacer washers to get the discs consistently aligned on all your wheels, will save lots of faff. I do see your point though, the tolerances are much closer so I suspect it could cause problems in that narrow field. Personally I wouldn't buy a bike without disc brakes now but then I'm not a pro or a road racer and I couldn't particularly give a monkeys if they use them or not.

That's true to an extent, thin shims could correct minor variations in hub dishing between wheels, but that's not the only factor in play.

Some calipers are worse than others, but the clearance when fully open is usually razor thin compared to rim-pad clearance, so even changing the skewer tension on the same wheel can have a deleterious effect.

It's only a matter of time until they get the technology dialled though and I'm looking forward to it, unlike some of the luddites here!
