Are there better V brakes than others?

Are there categories of V brakes? What do you look for in buying v brakes? Are they all the same? Do some stop better? what are the best V brakes?

XTR are the best I've used, higher end Avids are pretty decent. Basically you want the stiffest arm possible, without excess weight.

Avid Arch Rivals are better than XT. They don't squeal as much as the first few generations of XT. Not sure if they are better than XTR but they have to be a lot cheaper.

Squealing is all about the pads, or the angle of the pads... I don't think it would be a product of a particular brake arm.

The original XT had very loose pivots that allowed the pad to lift off and chatter no matter how you adjusted the pad. They beefed them up later but the early ones squealed like a stuck pig ever time you used them. Get really annoying on a 7 mile downhill. Corner...squeal. Too fast...squeal. Stop...squeal. My friends made me ride 3 miles behind them and they said they could still hear the stupid things.

They are all ridiculously expensive and light as hell.

Try a search engine for specifics on weight and price

Yes, some are better than others. High end Shimano brakes have a parallel push mechanism, which does exactly what it says. Cheaper V brakes move in an arc as you pull on the lever, and so the pad doesn't hit the rim 100% straight on.
As seely said, get as rigid as possible calipers and levers. High end Avids and Shimanos are the place to look. And don't forget the cables and pads. A high quality cable like the mountain bike Odyssey linear slick cable, and some nice pads will really improove the braking power, and are relatively cheap.

The big deal with the XTR cable is that it's a Teflon coated cable. Save a buck or two and get the generic teflon coated cables

Avoid any with pivots. Really, honest, they're not necessary. They add complication, potentially slop, and are an extra service point.

I'd take a pair of Avid Single Digits any day over their Arch series or Shimano's Parallel Push.

The fancy pivots square the pads to the rim, but they can't redirect braking force, which still is aligned as an arc around the pivot. For all intents, the braking force is "square enough" to the rim and pretty much similar between all the various brakes.

But the deal is, these cartridge pads most brakes use are so slim, there isn't enough material on them to worry about the pads wearing at an angle. The aren't the big honking brake pads of old (which would get a little skewed over time).

Avid's SD5 and SD7 brakes are both about the best I've used, compared to various Shimano, Tektro and Cane Creek V's over the years.

In the 4 plus years I've owned my Arch 40's I've never experienced this "slop" you speak of.

the Single digit brakes i am using right now wont stay centered for crap. Khuon reported that the Arch rival stay centered much better, they weigh a little more but im thinking its worth it

Ahh, but I said "potential slop".

I in fact rode a set of Arch Rival 50's for a season, and they were much more solid than the Shimano XT V's they replaced. My hangup with the Arch brakes was that the arch got in the way of the tire tread when spreading the arms wide enough to remove a wheel, and would clog with mud. In the end, they prooved to be just a little more hassle than was necessary (they were, however, quiet and fairly solid while I owned them).

I'm having the same prob. with my SD's... I hesitate to recommend them to anyone for this reason.

The arch on the Arch rivals doesn't do anything to help keep the brakes centered. The spring mechanisim is similar to what you find on the Single Digit series. All the arch is there for is the pads, nothing else.

FWIW, I've had SD5, SD7 and SDTi brake arms on various bikes at various times and never had a centering issue. But something I've observed is that in setup (regardless of brand/model), many folks tend to center their brakes by increasing tension on the side that is too close (and working back and forth). Like an over-tensioned wheel build, this causes each twist of the tension adjust screw that much more sensitive, leading to finiky brakes (not to mention higher than necessary lever resistance).

I like working the opposite approach, loosening the far side, keeping lever force low, and making centering less sensitive.

Me too. Seems to work better,(for me) if I get too loose =I unhinge the spring arms, tighten the scews, put the spring arm back on and start over. I don't RUN the springs low tension, I back the screws out carefully to keep the highest recoil I can.

It doesn't matter, they won't stay centered. They will be perfectly centered, and all the sudden "snap" to a off center position, drastically different from the centered position.

I've never encountered this with an Avid V brake and I've handled pretty much the whole line.

The only reason that I wouldn't spend a lot of money of 'v-Brakes' is that I just hate them. I would prefer getting a pair of cheap hayes disks,then going to v-brakes.
Why, you ask? AS soon as your wheel goes out of true , thats it. Gotta re-adjust the pads so they will stop rubbing. I also find V's loose power a lot quiker, since there more open up to water and dirt.

Of course in your case, I say dont spend too much on V's, save up some money for decent disks.

I say save up for a decent bike instead of polishing this turd. You can say you're going to put the parts on a new frame, but by then the parts will be "used" and you'll want the next thing

Well I was assuming he had a compatible fork and wheel. I agree, upgrading sometimes is just not worth it...especially when its a fork.

We're talking about a Y-26 here. Draw your own conclusions. I know I wouldn't have sunk the money he has into it. To each their own I guess
