V's or Discs?

Do you racers go for the light-weight of v-brakes, or the all-around stopping power of discs?

I don't race, but I have discs on my MTB, and Shimano dura-ace V brakes on my road bike, and I find that the shimanos stop as well as my discs.

I will say that I love my hydros (XTR) and I'll take all the stopping power and modulation I can get. I don't get the same power/modulation on my record equiped road bike. So for me, it's hydros, but everyone has thier own preferences.

if you really want light weight go for v's
if you are willing to sacrifice some weight for some stopping power get mechanical disc brakes(i am pretty sure hydros are heavier)

To see the real difference you need to have a muddy race and see how much mud build up in the v-brakes to the point of stopping the tire from spinning and also see what the built up mud does to the sides of your wheels when you are trying to stop. Disc brakes are the only way to go on a MTB.

I run discs for racing.

There's no way that v-brakes could stop me on some of the courses I've raced.

If you live out west where it is dry I would race v-brakes but in West Virginia where there is 6 inches of mud on all the courses, and v -brakes just stop your wheel from spinning I race disc. My Marta SL are pretty light I think.

ZeCanon come to SnowShoe,WV and you wont think what Never posted is BS.

Nope, V's were a product of the late 1980's/Early 90's.

Disc for me.

I'm not saying I prefer v-brakes. I don't. I'm saying they are adequate for virtually every XC situation, even if they may not be the best. Saying they "will not stop you" is a false.

Based on personal experience, the friction my v-brakes provided was always greater than that of my tire with the ground, meaning I could always lock them up and modulate them to some extent. If the conditions were nasty enough that my brakes weren't working very well, the ground was slippery enough that braking power was irrelevant anyway.

Like I said, I'm not advocating v's. I don't like them, except for their low-weight, and I don't run them on any of my bikes. But they do their job, and did for a long time before discs became popular. If you're on a budget, don't discount a good set of V's.

And sometimes discs "will not stop you" either, if you're going to be nitpicky about it. This year, after a stream crossing in one race followed by a short, steep, brakeless downhill into a rockgarden, my wet discs barely slowed me down for about 20m.
I never, once had a single instance where my v-brakes failed to stop me, racing in very wet New England as well as around the country on the norba circuit. They are capable brakes, so when people go around claiming they "will not stop you," I will argue otherwise. In most cases, I believe you would do the same (but since you are following me around rebutting all my posts, that is not the case here)
Sorry if my experience isn't enough for you.

ZeCanon, I really don't think it's a matter of whether or not a brake "will stop you;" it's more a matter of how effeciently one brake will stop you over another. For nearly any given condition, disc brakes are more efficient stoppers. Just because a V-brake will work does not detract from the fact that a better-working brake will improve your confidence in technical sections, make your riding more efficient and make you faster. To borrow the old motocross axiom, "the faster you can stop, the faster you can go."

I've raced a lot of XC - - on a more recreational level than my DH racing - - and I can definitely see the advantages to discs for XC racing. Given a choice, I would not be running vees any more on any mountain bike of mine.

Don't assume...this is a racing forum, not an XC racing forum. And the OP didn't mention any specific riding style.

The original question was whether racers prefer v-brakes or discs. Since there was a lack of input from the racing side of things, I gave my opinion: discs are superior, but for most racing applications v-brakes are up to the task. To say that they are not suitable for MOST xc races is false - even if they may not be the best. There are still many, many racers who run v's, especially in dry climates.
I wasn't arguing that he should run v-brakes. I was arguing that saying discs are the only way to go is foolish.

Remember, you're posting in a race forum, not an XC race forum.

And who said discs are the only way to go?
