Seeing disc brakes become prevalent will sell more bikes. Fact.

I'd agree they are by no means perfect at the moment, I work in a bike shop and we see a lot more issues with hydraulic disc's than we ever have with rim brakes. As we get a few generations in they will be more reliable and lighter etc.

You could also argue the pushing of road disc is a by-product of the strict rules the UCI have regarding weight limits and frame design. If manufacturers can't innovate with those two things they are going to have to find something else new to add interest.



This sounds like the voice of someone who knows.
Just curious, which issues with discs are the most common that are popping up with bikes coming through your shop?
I know Ive found road disc a pain the in butt to bleed perfectly, and it seems like pads wear pretty fast.... but haven't had anything break or leak....

Shimano road disc's seem to have had issues with the oil leaking through and contaminating the pads, On top of that we have the usual squealing/juddering/fading etc which I'm assuming isn't just limited to road disc. But we had a lot less back when they came stock with mechanical disc brakes (TRP spyres)

But disc brakes are the answer for the heat related and crappy braking problems of carbon rims :-)

Amazon still sells music in mp3 format. As Mark Twain once said, "Rumors of my death have been greatly exaggerated."

That's because the patent has expired and now anyone can use the format for free - a licence is no longer required. The format is not dead (but has, arguably, been superseded).

It's the only universal format that's supported on all devices.

Bike is 7.2kgs including pedals and on original 1635gm wheels. No WW but still some scope...

From your perspective, How does TRP Spyre perform in the grand scheme of things? Based on riders feedback, they work fine with Yokozuna compressionless housing, lighter, simpler and less maintenance.

^ i have used spare / hydro / juin r1 and shimano road hydraulic.

juin with compressionless housing is closest to shimano, but shimano significantly better imho.

actually the patents relating to MP3 are still current. the overseers have chosen to not licence MP3 any more.

Indeed, you are correct :oops: Although it turns out Fraunhofer's patent expires in December, so it was close to it in any case.

yes, i must admit I should be a little embarrassed too, being so pedantic as to quote a patent expiring in less than 6 months. and maybe my original point was wrong, and they have stopped licensing it as indeed it will be "open" soon and there will be no future profit to be made :oops:

anyhow, still, disc brakes do not belong on racing bikes :D

97 kg, lightweight clinchers, col du glandon, alp d'huez and galibier. No problem? And saw alot of people on disc brakes with problems on the decents. So maybe it's the rider?

Along the lines of "a bad workman always blames his tools"...not biting
You maybe right, may be the rider.

But isn't that just an argument for using discs?
