Disc brakes in pro racing 2019

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

Disc brakes in pro racing 2019

Now that disc brakes have been approved by the UCI and the increased use at the TdF this year, what are people's thoughts or insights into prevalence of disc brakes next year at the World Tour level? If they get widely adopted at the World Tour level, how quickly might we see this trickle down to the amateur racing scene?

2019? They've been plenty prevalent this year. And if you want to include cyclocross and mtn biking (remember, UCI is more than road biking), they've been de rigueur for quite a while now....

As far as amateur racing, may take another couple years to really penetrate as people upgrade/replace frames/equipment....

Me and the wife have watched several stages at the local Redlands Bicycle Classic the past couple years. Every year, more disc bikes. I would reckon about 15% of the men's field was on discs. The neutral support motorcycle carried two sets of wheels-- one pair of rim, one pair of disc.

I read that several manufacturers are doing some their road models in disc only configurations.

Seems to be the way things are going. As manufacturers embrace discs they may find less demand for rim brakes and eventually the cost to have a bridge on the seatstays and boring for front brakes might spell the end for a lot of rim brake bikes.
That said, the disc brake bikes I have tested do not seem to have any better stopping power than my '14 Chorus brakes.

I'd say slowly.

People that change bikes frequently may go for it sooner, but then there's still the issue of wheels.

Personally, I've got four bikes and about 6 pairs of wheels, including a powertap set.

One new disc bike will make all my wheels obsolete for said bike, so straight off the bat a new bike would also require buying another pair of wheels.

I won't be riding disc bikes anytime in the next five years, if not the next decade, personally.

Plus I have absolutely zero need for them. The speed at which I can take wet turns and corners and descents is solely dependent on my tire grip and skill, not my braking.

I would imagine that within about 3 years, the majority of pro bikes will be disc breaks. But for people that buy their own bikes and wheels I expect it will take much longer. Looking at rubiksoval's post above, I imagine that scenario is fairly common and making a change would be quite expensive. My guess is much of the change will be driven by newer riders entering the scene.

Several articles I have read on this have said the one thing that could upset things is if the UCI lower or remove the minimum weight limit, giving rim brake bikes an edge in weight.

Bike companies are selling disc brakes as an upcharge on many of their current road bikes right now. If they want to sell more expensive brakes to the crowd that buys bikes just like their favorite pro racers have than those bike companies need to get disc brakes on the pro bikes right now!

Within the next 2-3 years the entire pro peloton will be on discs, and the only bikes with rim brakes manufactures will produce will be the lower end models. And eventually it will be only Walmart bikes. Same as what happened to mountain bikes. They aren't going to keep making high end frames in both a disc and rim version forever, those days will be over soon weather people like it or not.

Exactly right. Discs will be the only choice on "mainstream" brands if you want something on the higher end. Too bad direct mount didn't ever gain much traction, I feel that was the best of both worlds (for road).

The synapse is a good example. I tried their upper end ultegra model at a lbs with the hydraulic disc brakes which were amazingly responsive. It was almost worth the price of admission. But I have just as much confidence on a properly set up rim brake bike. But if you are racing like these tour guys I would imagine disc brakes are an incredible advantage on a descent coming out of a tight bend.
