What will it take for you to accept disc brakes on tri bikes?
Quote | Reply
White papers? Every manufacturer stating it's slightly faster? Pube's upcoming test? AeroCamp results? ERO Velodrome? Tom A. finally giving the approval? We can go around and around and around in circles about this but what will it take for YOU to convert?

Just curious as someone who rides a 2011 P2 and is wanting a new bike next year.

Nothing. I hate the way they look. Besides, I've never been in a situation on my tri bike where I thought the stopping power of rim brakes was inadequate.

Simple - when a bike I lust after happens to have disc brakes, that's when I'll switch.

Pube's test? lol, right..

A clear, compelling and convincing argument that has yet to be made.

I can accept disc brakes on anyone's bike, but I don't want them or need them on my bike. Just don't need them. I barely use the brakes that I do have :-)
I am hoping that when the time comes that the bike that I want doesn't have them.

My biggest concern is ease of use/maintenance. I have disc brakes on my fat bike and had them on my mountain bike and they've always been a bit of a pain in the ass to maintain...primarily to keep from rubbing. Even the slightest rub drives me nuts and I've never been in a position where I felt I needed them so the potential utility isn't enough to outweigh my pain in the ass experiences.

Let others be beta testers. When majority of you are on disks, I'll switch to disks too, but only next time I'm buying a bike. I would not go out of my way to "upgrade" because it isn't an upgrade.

If disks don't catch on, then I don't want them either.

Why? Wheel swaps if my race wheels are damaged. That's why.

Whenever I am in the market for a new bike (~1-3 years from now depending what mfg's do) and I can no longer buy a superbike with rim brakes.

I really don't understand disc brakes on tri (or road for that matter) bikes. It seems like a solution without a problem. I've spent a LOT of miles in mountains (1000s of miles in Northern Colorado)...I just can't ever recall wishing that I had more stopping power than I was able to obtain using my rim brakes. Even doing the 100 mile loop to the top of trail-ridge-road and back, in the rain...never once. Just. don't. get. it.

Now that I'm in Texas, the only time I touch the brakes is at stop lights.

With the extra components, cost, weight, complexity, and presumed aero tax...where is the upside?

I admit I'm only recently back in the sport after a long hiatus, and haven't done any research on this topic yet. So, maybe I'm missing something.

My next bike will be disc brakes... at least five years from now, when discs will have become the defacto standard for all bikes.

I'll accept it as soon as my Andean gets here.

How about highly reliable braking on long steep technical downhills where neither the disc rotors, nor the calipers, nor the pads, nor the hydraulic fluid fail at any time in any realistic situation?

In other words, if a disc brake system can work as the primary brakes on a tandem (and currently they can't -- they fail catastrophically), then they'll work on a single rider bike too.

Finally, will such reliable disc brakes be more aerodynamic than state-of-the art caliper brakes? If yes, then I will be stunned. But I will accept them for tri.

When a compelling use case scenario actually is advanced that is not overly dependent on developing new marketing opportunities. FWIW, Cannodale's new disc TT bike yesterday wasn't overwhelming ;)

First, I need to be in the market for a new bike. Second, I would need there to be no bikes I wanted to be without rim brakes. Third, I would have to be able to get disc wheels for racing without losing too much money on selling my rim brake which would be near impossible if the switch actually hits mainstream. I don't think I have an issue with disc brakes but I have an issue with need to get new wheels along with a new bike if I made the switch.

Here's a observation that has not been mentioned. At least I have not read of this on any thread regarding disc brakes on road/tri bikes. I was in Seaside, FL last year and friend of mine brought her Mtn Bike over to ride the trails. 1/2 thru the ride she squeezed the rear brake and the rear brake caliper froze up closed on the rear rim. Rear wheel was locked and could not turn the wheel. Had to bleed the line to relieve the pressure and the rear braked unlocked. She dropped it off at local bike shop and their response was the lack of use and the build up of moisture inside the line cause the rear brake to seize.

Can u imagine hitting your brakes at the turn around at IMH and this happens?

My take on disc brakes are this:
1) Timming is bad...people just had to upgrade wheels from 10spd to 11spd not to long ago. Now u have to upgrade wheels again but add a new frame and new hydraulics.
2) Frame manufactures rushed to make frames work for disc...for example: look at Cervelo R3 disc(lets just drill a hole in the side of fork to run the brake line...that took a lot of thought) Other companies did it to.
Frame manufactures still have not made a frame/fork that's seamless to accommodate the disc brake itself.
3) Frame/wheel manufactures have not made frame/fork/wheelsets/disc brakes that weigh the same or less than rim brake frame/fork/wheelsets/brakes.

2) and 3) should have been addressed before the big push to change in my opinion but that would have cost the manufactures money.

Also, if manufactures are going to do disc why not make the frames accommodate potentially the next increase in cogs from 11 speed to 12 speed and above?

Your question is worded poorly. I have accepted that their are disc brakes on tri bikes. Not accepting it would be like me saying that the world is flat.

Now, what would it take for me to actually buy one of these things? Well, I'd have to want a certain bike that just happened to have disc brakes. And not only would I have to want it, I'd have to want it enough to deal with selling all of my non-disc wheels and buying the new more expensive disc versions.

I don't see that happening anytime in the next 5 years. But that may be just because all of the new disc tri bikes out there right now are uninspiring.

That's when I will switch. When I don't have choice.

Pretty much this, and to actually have enough money to buy a new bike, regardless of which brakes it has.

I will run rim brakes on my tri bike until they stop making them.

I think my problem is I want a new bike in 2018. Specialized will most likely have released their bike by then. Why would I want to buy a P5 frame when the P5-X and all the other bikes with disc brakes are out?

Because it's faster.
