Will you ever go disc?

Notices
Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Probably because you're more familiar with rim brakes from years of use. My first road bike was 9 years ago and I don't recall my early rim brake servicings to be any less fiddly or complicated.

edited to add: as far as your first point, I actually view hydraulic disc as being easier in terms of servicing because brake pad changes are easier and more involved servicing is less frequent.

I once tried to convince tommasini to make me a lugged steel road bike with disc mounts but they refused. that would have been kick ass though! I guess they can do it but they just dont want to.

------------------

as opposed to everyone else in here i actually strongly prefer mechanical discs. They are pretty much as simple as calipers to work on and have about 80% or so of the modulation/power that hydros have. But when something goes wrong with hydros i can be a 3 hour job, and in some cases you will never be able to fix the problem. Not so with mechs. So i prefer them basically because for me they are less of a hassle to keep going 100%. KISS principle applies.

Also my shimanos freeze up to solids at -25C. BB7 not so much.


I built my first road disc in 2008-9 or so. and then there were no road disc hydro levers at all. So cable it was. and it was a good choice in retrospect.

Yeah, Iím not sure how it provides better modulation when it locks the brakes with less lever travel, but ok.

I have very recently ďupgradedĒ my 10 year old Edge 500. I think I am safe in the sense that rim wear on expensive wheels will be a problem Iím to experience, considering it is very highly unlikely that Iíll spend $1000 on a single rim.

For the record, I do own a bike with cable actuated hydraulic disc brakes, I just donít believe I need that much of stopping power on my road bike. Thatís all.

That's "okay".

I'm sorry that you don't have the capacity to modulate your brakes.

Simples. Less travel to locking, less range to modulate.

Looks like someone is lacking reading comprehension, but whatever. If it makes you feel superior, more power to you. Letís not converse again until you gain some intellectual ďcapacityĒ.

Not in my experience. Travel is more or less the same, but there's less effort and better feedback. Simples.

Perhaps. In my experience, I find the lever travel to lock up to be more on the rim brakes. Iím on my last set of kool stop salmons though, and they do compress more compared to the black Ultegra rubber that came with the group set.

bb7 road gives the exact same lever travel as calipers.

Brake levers aren't simple on/off switches. Hydraulic discs require less effort to increase braking than mechanical rim brakes. Less effort = less fatigue.

If you ever try a long mountain descent, you might one day understand why this is important.

I did. For like 3 weeks. Wasn't for me. Disc brakes are amazing. But I find them equally annoying. I love pulling most parts of my bike apart and throughly cleaning periodically. Having to bleed brakes when you disconnect hoses sucks. Discs also rub. No matter what your experience is, I don't care. They rubbed on all disc bikes I've ridden. I set it up perfectly. They would be dead quiet for couple hours and start rubbing afterwards.

I love the modulation. I love the rain performance. But my best descends are still on my rim brake bike. Handling characteristics of a bike have much more impact on descending than brake performance IMO. So the usual "you descend faster on a disc brake bike" is a bunch of BS.

Anyway.. If the brake rub is completely eliminated, weights significantly reduced and if they come up with a system like after market motorcycle brake lines where you can disconnect cables without introduce air bubbles in to the system, I might check it out again. Also quick bleed system like motorcycles where you undo a bolt, squeeze the brake 3-4 times and tighten (where the squeeze pushes bubbles out but doesn't let air in)

I'd like to change my answer, now that I have experience with hydraulic disc brakes. They are fantastic!!

I bought a gravel bike with 105 hyd brakes, they are great offroad, as expected. What really surprised me was when I put on a set of wheels with road tires and took it out on my normal 40 mile loop today. They are confidence inspiring. I can go into curves with more speed, brake later and harder and still have more control. They are absolutely better than the rim brakes on my road bike (direct mount Ultegra), with either alloy wheels or carbon with textured brake tracks, there is no comparison.

I'm sold. My next road bike will have discs.

One important issue in the disc vs rim brake debate: What do the pros use? What the Tour de France riders actually use will drive the market as well as anything else.

No pro team will use something that gives them a disadvantage!

My old bike had 17,000 miles on the same wheels and the rims were not worn down to the wear markers. My disc bike has just over 1,000 miles and there is about 1 mm wear on the disc!

That's odd because from what I've heard the possibility of a Chinese throwing rotor keeps these pros up at night in a cold sweat, but also from what I've heard "the industry" has made the choice for everyone, there will only be disc braked bikes by next Tuesday, Obama is going around confiscating people's calipers.

I change out wheel all the time. I flip fix gear wheels, have several wheels for each dropout width standard with different FW/cassettes and tires and borrow wheels of different bikes. No desire for yet another wheel standard. Love how easy rim brake wheels are to swap. Plus light, cheap and easy to maintain. And it gives me an excuse to do my favorite hobby without going into wheel N+1, replace the rim and rebuild the wheel.

Ben
+1 I already have to "pay attention" between a few Dura-Ace 7 speeds and the rest of my rear wheels when swapping . That's enough non plug and play for me. I really like to ride the bikes they fit or I would consider dumping those wheels just to simplify. I'm fine with rim brakes in the rain, my old carbon wheels are mostly for show, and can wait for nice weather, since I'm not competing.

hydros can be finicky setting them up and adjusting them. basically there is never the same the same friction in 2 or 4 different pistons. so its much much morwe likely to rub on any side/piston. no matter the actual system or maker. they are all affected by this. all hydros work like this. almost impossible to keep them from rubbing over the long run.

Get mechanicals instead. i have bb7 road and bb7 mtn and they are much, much dependable and less finicky than hydros. by like a factor of 100 or so. no S! seriously.
i simply laugh at the idiots insisting on hydros. they dont know jack S. But they will find out how all this works soon enough! hahaha.

whyfi.

well he mentioned "discs also rub" which is actually the most common "problem" with discs. hydros that is. because the fluid in the lines and calipers expand with temps and with water/air content (that they may or may not), absorb. I simply explained how i solved that very problem. and its a very elegant solution.

Yeah i've only been on discs since 2008, as my only form of transportation, so w t f would i know about discs right, doing only 7-10000km a year or so.

but yes noodle soup i gotta hand it to you, you are obviously better at posting on the internet than me. because you see, i actually have a job. a very demanding one.
