UCI expected to approve Road Disc Brakes for 2016

[jasonc]

Being the wrong side of 80kgs and doing over 1% climbing I get about 3000kms out of a set of front pads. Rear pads were still good when I upgraded the rotors

Thanks Jason, give we do the same climbs that gives me a rough idea.

I think I'll order up the replacements because I guarantee they'll become unusable at approximately 5pm on a Saturday otherwise.

From what I've been reading it looks like the 500-1200 miles estimate is one of those things that was stated on a random internet page in 2014, and has been quoted everywhere else verbatim; half the time being used as an argument against disc brakes. Looks like people can get anywhere from 2500km to 7000km depending on usage.

Mine literally look brand new.

In a (slightly) related thread - what sort of mileage is everyone getting out of their road disc pads?

I'm by no means a typical user at 59kg's, no traffic lights and only use the brakes for a few sweeping downhill bends and arrival back home.
My disc braked bike has clocked nearly 16,000km's and I've only changed the front pads once at about 10K. Plenty left both front and rear.

[jasonc]

Mr purple - my brother is a flat land rider in comparison to me and he's got double out of his front pads
Those numbers you mentioned sounds very MTB to me

You could give metallic pads a try. They last longer, especially so if you ride in the wet.

The downside is they are more likely to be noisy in the wet and they lack a little bit of initial bite in comparison to the resin pads.

[Mr Purple]

Mine are metallic and at 61kg I’m probably not the greatest load so that all makes sense, thanks.

I do descend a lot but not exactly emergency stopping at the end of them, so probably that also helps.

I may or may not have bought the 25 pack from pushys when on sale. The resin are fine. I have lots

I’m the same. I have a few disc bikes, and average around 10k at the front

About 12,000km out of mine IIRC - unfortunately lots of braking needed, plenty of stop starts and braking to avoid unpredictable people.

I'm 59kg so I'm also pretty light. SRAM Red disc brakes on Cervelo S5 (SRAM E-Tap AXS). Mine have the non-metallic pads.

I'm always mystified by the not making 6.8kg with disc brakes thing given quite a number of manufacturers have gone under the 6.0kg mark with disc brake equipped bikes. Canyon had a ML size disc brake Ultimate CF Evo back in 2019 that was about 5.8kg IIRC. 1kg under. Even with pedals added to it that will be well below the limit.

I've loved the disc brakes when trying to do local rides in my LGA during the lockdown, the added stopping performance has allowed me to avoid hitting people doing random sudden U-turns.

Finally have a disc braked bike.
A Revolt Advanced running Shimano brakes.
Do the metallic pads make much difference to brake disc wear/life?

Edit;

Had a read of this;
https://bike.shimano.com/en-US/informat ... to-kn.html

This was interesting
Mix it up
Still can’t make up your mind? Well, it turns out that you don’t have to. Some of the top professional racers in the world, including some members of the famed Santa Cruz Syndicate downhill mountain bike team, often run mixed brake pad set-ups. The idea is that since the inner brake pad typically wears quicker than the outer, you run a metal brake pad on the inside and resin on the outside. This allows riders to reap benefits of both the materials while minimizing drawbacks.

Prob try resin for better progressive feel if that article is accurate.
Doesn't say much about disc wear.

[Nobody]

In the past I've found resin to have a bit more initial bite. Sintered wear better. As for disc wear. Sintered are supposed to wear discs out faster. But discs last a reasonably long time anyway and are fairly cheap to replace for basic ones.

Thanks mate

Pogacar uses disc and rim, and weather not a factor in choice.

I imagine 'braking performance' is not even in the top 10 reasons why you'd win a professional race. As long as they can't make 6.8kg I'm thinking brake choice would be irrelevant.

In a (slightly) related thread - what sort of mileage is everyone getting out of their road disc pads? I've seen reports of anywhere from 500-1200 miles on average but just checked out mine at 2500km and they still look brand new with a mile of pad left on there.

Being a bit OCD about cleanliness and 61kg might make a difference, I'm just wondering if I'm missing anything.

I just looked at the spread sheet.. last new set of pads was 23k.. and I'm currently up to 38k

oh damn.. you mean disc pads not rim pads.

“I think it’s still a technology that is a work in progress for road bikes and there are still some issues for pro races. But it’s a technology that is evolving and I’ve been working with the guys from Factor. I’m one of the owners too, so development and feedback comes with my role there.”

“We’ve actually ironed out most of the issues we were having earlier this year with disc brakes,” Froome added

[MichaelB]

Not really, just realised he was wrong

Duh. The issues were *always* solvable with a "how can we make this better?? mindset.

This

[AndrewCowley]

Not really sure I’m buying this. We are supposed to believe that a pro team, with presumably the best mechanics in the business and deep manufacturer support, has only just worked out disc brakes?

Could it be that Froome, given his underwhelming performances this year, has been given the tap on the shoulder and been asked to tow the line?

[MichaelB]

So, reckons that there have been changes/improvements from suppliers, but doesn’t say what.

From all the press I’ve seen, everything to do with disc brakes is in, the same. Even the 9200 DA group set uses pretty much the same fundamental parts with no new tech or revised design.

Think his “acceptance” is more about publicity and part-owner endorsement. So no change actually.

Meh

And what issues were those? There are loads of brilliant disc brake bikes out there already and some of them are 1kg below the UCI weight limit. The disc brake bike I have is amazing. Sure it's not one of the lighter ones but everything else it does beautifully. The braking power, how precise the brakes feel to use, the handling, everything.

I think that's right too. But we've got to some how keep this whole disc brake debate going to reach 1000 pages right?

The new 8100/9200 series have more clearance for the rotor.
I agree with your statements

AFAIK, the measurement is less than 1/2 a mm. Or in technical terms, a bees weenie.

That ain’t any difference, just marketing

[warthog1]

No expert on disc brakes.
My new bike a Giant Revolt Advanced 2, has Shimano running gear and brakes.
GRX RX600 levers.
GRX RX400 calipers.
My understanding is they are equivalent to 105 and tiagra in terms of road componentry
Hardly top of the line.
No complaints here though.
Great power and modulation.
No caliper rub, no squeal, no probs.
There is no apparent problem in need of drastic improvement.
No hurry to upgrade or change any of the componentry.

Best road bike mechanics in the business. It's entirely possible to be outstanding in a narrow field and struggle with new stuff that comes from left field. Kind of like being an outstanding orthopedic surgeon but being early in the Dunning Kruger curve with regard to epidemiology - as we've been seeing more of lately. Disc brakes are new tech for them. This commentary doesn't surprise me.
