Road Discs
So, my SuperSix was crushed in a roof-rack accident and last weak my Roubaix was stolen out of the garage that I left open all night. I've done that many times -- apparently one too many. I'm down to a gravel bike and my commuter -- the reborn warranty CAADX (which is a great bike).
The gravel bike is a pig, but I'll use that for fall/winter/spring sport riding. I want a fast bike, though -- and I've got a line on a nice bike that I can get with rim brakes or discs, but the disc model will not be available until December -- which really means that I get to ride it in dry weather some time around May. I can get a rim brake model by the end of the month. All the shops are pushing discs, and I did like the discs on the Roubaix and on my gravel bike. I know this is absolutely the wrong group to ask because it's wall-to-wall curmudgeons, but if you were buying your last nice road bike, would you go rim brakes or discs? It will be a dry weather bike or ridden in the rain only because of bad luck. There would be no real weight penalty because the bike is so light to start with. I'm not aero, so I don't care about the aero penalty with discs. My concern with getting rim brakes is not really even a performance issue because in dry weather, I've never had a problem with rim brakes -- but to listen to the guys at the local shop, rim brakes are going the way of the dodo. I'm worried about buying an antique! -- Jay Beattie. |
Road Discs
I have no experience with disc brakes. None. If building my new dream bike, it would be rim brake. I know rim brakes. Rim brakes are easy to work on. I'm not against learning new things, like disc brakes. But don't see the need. They are not as simple to work on or understand as rim brakes. In all my riding, I've always been able to stop just fine with rim brakes. Loaded touring bike down the Alps, Dolomites, Rockys. Never a problem. Never over heated a rim or burnt up brake pads. I've also ridden in rain and stopped just fine too. Maybe in emergency situations in the rain, the performance improvement of disc would matter. Maybe. But I don't ride crazy and ever need to stop instantly. And disc brakes still need time, distance to stop just like rim brakes. Maybe less distance but I don't see that ever really mattering to me. So my dream bike of the future would have rim brakes.

So, in my opinion waiting until December makes no sense. I'd go for the bike I can get now. Who the f*ck you calling a curmudgeon? :-). -- duane |

I spoke new rims to the old hub and spokes. Since I have very little practice doing this, it takes me maybe 4 hours to get the spokes transferred, the wheel reasonably centered and round, and the spokes evenly tensioned. 2) I bought a mountain bike with disc brakes last October. The first change of brake pads came in April, and a few days ago I had to install a new disc on the back wheel (the original disc was worn to the safe limit). Both things are a lot quicker than spoking a rim, but at least here in Switzerland rather expensive. 3) With rim brakes I would have pain in my hands from braking during a long descent in the mountains. Much less or no problem with disc brakes, which require less pressure. But I'm old, and a younger person probably wouldn't notice this. 4) Again as an issue on very long descents, I no longer worry about a tube failure because the rim overheated (happened to me once many years ago, https://flic.kr/p/9XmmWn ). Disc brakes can also overheat, and then fade, but this hasn't been a problem for me. Overall I prefer the disc brakes, but should note that I have no experience with road bikes. Ned |

Disc for road bikes are coming that is for sure and they do brake an order of a magnitude better than rim brakes in the wet which I found out again during my trip this year to the Dolomites in bad weather. Set up properly they are very low maintenance (my cross bike). The only argument against them is the weight penalty of about 500 to 1000 grams. In one of the last issues of TOUR magazine they measured no aero penalty to their and my surprise. Once the pro riders going to use disc brakes rim brakes will get obsolete if you like it or not. What I see is that more and more road bikes offered for the next season are disc only... Lou |

Disc brakes can also overheat, and then fade, but this hasn't been a problem for me. Overall I prefer the disc brakes, but should note that I have no experience with road bikes. Ned, my experience is that the so-called advantages of disk brakes are their downfall. 1. Where you need the brakes the most - descents particularly on twisting roads or sharp turns and the like - you have your hands on the brakes. Disks are so powerful that if you hit a bump you are very likely to pull on the brakes while trying to keep yourself from being thrown off of the bike. This pulls the brake on and with all it's power can stop the front wheel completely rotating the entire bike around the front wheel. Voice of experience. 2. Because the whole idea is power the leverage has to be effectively very high. This means the distance of motion must be very low since the lever has limited motion due to your hand size. So brake pads are VERY thin and because they are small they wear very rapidly. 3. Yes it's easier to replace a disk than a rim. In 40 years of riding I've had to replace one rim from brake pad wear. Since I built many wheels it took me a half hour from start to finish. But of course I do have a wheel stand and spoke tools. Now in Switzerland you may have a hell of a lot more sharp and dangerous descents than we do around here but in the last five years on just ONE altimeter that I used on only some of my bikes I do have 57,000 feet of climbing shown. I have worn some brake shoes to the extent that I replaced them. But only on super-light alloy wheels have I ever shown extensive wear. And I find buying new wheels generally cheaper than buying a new rim. I just bought two sets of Campy Scirocco CX's (stronger than the road version) for $240 per set. These are cheap wheels but I am getting tired of spokes breaking on the lighter road wheels. |
