One Man’s View Of Disc Brakes

I make similar adjustments when riding my bike in the rain as I do when driving in the rain. It rains enough around here that many riders own rain bikes. Wet roads effect braking, No matter the system. We have ‘New Locals’ bouncing off the Jersey Barriers all the time late fall when the rainy season starts.

All this talk about what is and isn't affect by rain/wet is hilarious. We already worked this out in cyclocross. 99% of the bikes I see there now are disc except for a few carbon canti masters racers who readily admit they are sticking to inferior carbon wet braking due to cost

And they weigh 50 to 100 pounds. Nobody has ever climbed a hill with a disc brake bike. The only good thing about them is if a thief ever tries to steal your bike they'll throw their back out. The only reason anybody likes them is brainwashing by the bike industry, they put something in the water and in contrails from jet planes.
Step 1: Kill off rim brakes
Step 2: ???
Step 3: Profit
Seriously, the things people seem to believe about them are kind of goofy.

Rim brakes will kill you in the rain. Disc brakes will slice up bodily parts. I'm taking the brakes off all my bikes.

Laugh all you want. I can't hardly hear you any way. Your discs squeal too loud ... ;-)
Have no ide why ppl have such a hard time with this. It's just fact. Discs squeal and loose brake power in the rain. Rimbrakes are crap too. Especially with carbon rims.

One point I would make is about disc brakes on group rides has to do with how quickly a few of our riders in a pace line will decelerate. I don't know if this falls under "modulation" or what it is but one particular lady who is quite fast who is riding a 2019 Specialized disc Tarmac has almost gotten rear ended by me and my Dura Ace 7800 dual pivot caliper/Mavic Open Pro rim brake on a couple of occasions. Partly (maybe) it might be me decelerating too slowly but mostly it is her decelerating too fast.
Just curious if over braking has been an issue with other road riders. It seems that hydraulic disc brakes on uber lightweight bikes ridden by lightweight riders is the main culprit.
The new titanium Wittson disc frame that I just bought that will be built up has specially curved rear seat stays to accommodate 160 mm rotors to go with the 160 mm front rotors. This sounds like a lot of braking power to me. Which is mostly a good thing. I'm looking forward to finding out.

I don't know if you've heard, but it rains a lot in Seattle. People who ride here, a lot of us have been doing it long enough to have ridden rim braked bikes, those used to be a thing. Everybody who's had experience riding both types of brake systems in the rain thought you were pulling our legs.

It costs a manufacturer more money to design and build disc and rim brake variants of the same frame. Most of the top end frames still do come in both versions, but I can understand why the manufacturers are moving towards disc-only designs. No, I don't much like it, but I can learn how to do my own maintenance on hydraulic disc brakes if I have to.
And now I'm off to yell at Cannondale for not making the rim brake version of their new Supersix Evo Hi-Mod available to the public.

Would you pay a premium for discs, though?
I like discs from the little time I've spent on trying bikes with them. However, would I pay a premium for them? Probably not. Not for the riding I do. For me, direct-mounted rim brakes work awesome, especially since you're likely saving in the neighborhood of $400. That's a decent chunk of change.

For an overseas touring bike, I'd like discs, but with V-brake posts on the frame in case something goes wonky and I need to fit V-brakes in a pinch. Maybe this will not be an issue as discs become ubiquitous, wait, let me be more specific... as they standardize mountings, calipers, rotors, and pads so replacements are ubiquitous. I suppose that would stifle innovation, so perhaps not good. So for overseas travel I would spec the brakes for high reliability and high availability of parts. Or carry one spare caliper, rotor, disc, pads.

Endless adjustment due to the pad wear being magnified by the mechanical advantage necessary for discs. Those with disc bikes and cable levers should all be using a hybrid caliper like that TRP number.

i have tried TRP spyer to Juintech F1 and now to 8070 di2 Hydro, yes full hydro will allow 1 finger braking from the hood where cable and hybrid would require at least 2 fingers. In the drops, there is little difference because you get alot more leverage on the lever pull. The pad wear adjustment on cabled disk is simply a turn of a screw, it takes 1 second to do and not a big deal. If you are doing so much braking that you wear out the pad on a single ride, I guess you should go full hydro.

But yeah, a decent brake instead of yum cha junk makes adjustment much less hassle.
