Disk brakes
So if I go the disk brakes route thinking Lynskey. Option for mechanical or hydraulic, what is the better option? Are either of them really all that hard to keep working with properly? Seems if you have bleed hydraulic that would be a little more but nut rocket science.
Finally I really do fine with standard rim brakes but seems the future is only in disk. I can only see a downside to rim brakes in going down long mountains and heating. Rain would make them better too. Could all be completely overblown too? Deacon Mark |

I can only see a downside to rim brakes in going down long mountains and heating. Rain would make them better too. Could all be completely overblown too? Deacon Mark I prefer hydraulic discs, and on some bikes, the cable runs for mechanical disks add too much cable drag for weak return springs and you end up with pad drag and weak braking. After initial installation, bleeding is unnecessary (at least for Shimano road discs), and the only thing you need to do is watch pad wear. The brakes self-adjust, but you can find yourself braking with the aluminum pad carriers. Set up is easy -- far easier than cantilevers. Pads are expensive, you will need a bleed/install kit (assuming you're building the bike) and will have bikes with different wheels -- and you will have to deal with odd-ball through axle standards (12mm/15mm). You have to buy rotors. If this all comes OE, then no big deal except the cost of pads. Also, hydro discs means either 10/11/12 speed, and if you had your heart set on 8sp STI/Ergo, you're out of luck. I don't know of any hydro levers-only for road, so if you had your heart set on DT shifters or bar-ends, you'll have to shop around. Wet braking with discs is superior to rim brakes. There is no rim wear, which was a problem for me riding in the PNW. You can use whatever rim you want (CF, aluminum, dimpled steel) and can use whatever tire fits your bike because there is no brake arch or straddle cable. Great fender clearance. I have discs on my wet weather bikes but not on my racing bike (descriptive term for bike type and not my use), but sometimes I wish I did because even in dry weather, my poor rims are getting ground down. OTOH, rim brakes on dry weather bikes are fine, light and simpler. They work well for most people. IF I were building a one-bike solution, it would have hydro discs. -- Jay Beattie. |

"I do fine with rim brakes but I'm getting disc" is a very common meme these days! I've gone down mountains with rim brakes and heavy loads. I was aware of the potential problem and was careful about it, but I never had that problem. For people riding mountain bikes in mud or (like Jay) commuting in six months of rain, discs make sense. For others, not so much, IMO. I have only a tiny bit of experience working on discs, so I'm not qualified to comment on hydro vs. cable, etc. My only advice is to buy extra pads early (maybe on sale?) and carry one set when you ride. I'd worry, perhaps needlessly, about someday being told "Oh, you need pads for an Acme 1100-Z disc brake? Dude, that's SO unfashionable! They stopped making pads for that one five years ago!" -- - Frank Krygowski |

Now the question is how much do replacement pads cost. Personally I can see no reason to go to disk but in the rain would be the first reason. I live in Illinois so we are flat as a pancake. Not sure the longest descent in the mountains I have done but not done a lot of riding in mountains. One time around Bozeman Mt and I did fine on a rental bike. I would like to travel and do some riding in mountains. The steepest grade of any length I have gone down is about 6% for a mile and feather the brakes but have no idea how much you have to descend until brakes get hot. One other item is taking the wheel off and on any more tricky or harder to line up. Seem they don't use quick release levers? I would hope it is easy to set up because would not want brake rub.

One other item is taking the wheel off and on any more tricky or harder to line up. Seem they don't use quick release levers? I would hope it is easy to set up because would not want brake rub. Through axles have guides that line up the wheel, and the axle places the disc in the right orientation. You will not get brake rub if the calipers are properly installed unless you bend a disc. It takes five minutes to learn how to deal with through axles, if that long. It is faster to remove a front wheel with a through axle than a front wheel with lawyer lips and QR. I never had a problem with brake fade except on a tandem with cantilever brakes -- after over heating and blowing up a front tire. On a single, I don't think it is an issue with rim brakes or discs -- at least not on a mile of 6%. I'd probably go with the disc on a super-steep decent, but some of that is avoiding hand fatigue. -- Jay Beattie |

I used to stop every mile or two and feel my rims, and never found them the least bit warm. But I never feathered the brakes. I would coast until I started feeling a bit nervous, then brake hard until I was going a bit slower than I preferred. If the road was straight and the pavement was good -- neither was common -- I wouldn't brake at all, but count on the following climb to slow me down. -- Joy Beeson joy beeson at comcast dot net http://wlweather.net/PAGEJOY/ |
