More toys and tech for you to buy. Soon, bike geeks the world over will wonder how we ever rode bikes without discs and computers.

I'm in the market for a new bike and I'm really thinking of getting disc brakes, but still not decided. The best argument for me that I've heard so far is that disc brakes are far superior in wet conditions.
I'm still reading thru this thread, so not sure if this has been covered yet, but any thoughts?

I ride in the rain and mud a lot. They're way better than rim brakes once mud gets involved. That and you pretty much never wear your rims out with disc brakes. I used to go through about a set of rims a year on my commuter and touring bikes before I switched those over to discs.

I just bought a disc bike because of all the rain we've been having. I'd say ... meh. Unless you ride in a lot of rain a lot ...
For a gravel bike, for sure. MTB, full hydro or stay home. Road bike .... the wide tires might make more of a difference than the brakes most of the time.

if you cannot lock up your brakes, your brakes suck.
If you have wider tires, and run at lower pressures, you have a larger contact patch, which means you can exert more braking force before locking up your brakes.
Did you not notice that your only contact points with the road while riding (if you are doing it right) were the tires?
There is a big difference between 23-mm tires at 120 psi and 28-mm tires at 90 psi.

Guess I'm in the same boat as some. I'm ready to pull the trigger on a new road bike. Either a Cervelo S5 or Specialized S-Works Tarmac. Can't decide if I should go with rim or disc brakes however I'm starting to lean towards disc.

But that has nothing to do with rim brakes vs. disc brakes on a road bike.

I stated all this very clearly and the concepts are all quite simple.

I am following the conversation. But your comments about tires and tire widths are taking it a different direction than the original topic of discs vs. rim brakes. Your talking stopping distance in relation to tire width which has nothing to do with disc vs. rim brakes.
Ummm no. Disc brakes will grab and hold under all conditions. Rim brakes won't. Lots of sliding and drying before they catch.
However, hydraulic disc brakes generally provide significantly more stopping power than rim brakes, especially in poor weather when rim brakes will have difficulty gripping the wheel. Disc brakes keep on working even when wet.

If the rim brakes have difficulty gripping the wheel when wet, it ain't gonna matter how wide the tire is.
i think the wider tires have more to do with stopping power than the type of brakes.

yeah, it's funny, if you actually respond the things I actually said ... you have nothing to say.
And the world is a better place.
By the way ... I have well over a decade of daily riding in hard rain on rim brakes ... and now a few wet rides with discs. I don't need some guy on the internet or in a magazine or any of that to tell me what's up.
Happy to discuss stuff with you. Just please take the time and make the effort to figure out what I already said before you tell me what i should say.

I'm having flashbacks of the road section I left a year ago. You guys kiss and make up, or go over there. There's more important things in life to stress about than bicycle brakes lol

Dude, you need to have an attention span and concept retention a little more than that of a gnat to really hang on the internet.
Notice the emphasized part?

....and on long and/or steep hills....
...or any time I find myself braking hard.
Other than that, I don't see the point.

With the rear wheel, probably yes because it's a simple matter of weight transfer. With the wide, front tyre compressing and gripping, the rear wheel will become 'lighter' increasing the chance of lock up. If the rider leans forward, rear wheel skids, even stoppies should be possible.
