Guest Big H Posted November 20, 2006 Share I came in late on this discussion. When I upgraded my Tandems wheels to DMC Revolver hubs I went for the disk hub. I also fitted Avid Arch Rival V brakes. Have never adjusted them exceptwhen I change between slikc and knobblies. They work verrrry well on the Sun Mammoth rims, very wide braking surfce and dissipates heat amazingly, they work just like disks.(i think!!!!) The time has now come to upgrade. I am going to fit the new Shimano XT derraileurs and shifter pods. I am torn between the following disks:-Avid Juicy 7's, Avid Coda????? DH brakes or Hope Mono 4's, They will all be with 185 mm rotors. I will be fitting a cro moly front axle to the Revolvers but do not contemplate upgrading to 20mm through axle. This would mean upgrading the Marzocchi as well. Just too much money. Will fit a Mavrick DUC one day. Please help me with comments on the three disk sets above????

GoLefty!! Posted November 20, 2006 Share Rim Brakes aka as V-brakes: Light weightbetter braking torque than Disc brakessimpleeasy to set up and maintainStopping ability limited by tyres Disc brakes:Always heavierLots of force from hydraulicsmore consistent thn V's in the wet metals pads outlast rim brake pads in allconditions.Stopping ability limited by tyres. If you choose V Brakes then;Magura HS-33 Hydraulic Rim brakesShimano XTR V's are the best , by far.Avid Single digit and Cane Creek come in behind. If you choose Hydraulic Disc brakes:Shimano XTR, Magura Martha are th pic of the lotAvid Juicy is nearly as good but heavier.Formula Oro have rcieed grea reveus but never used them so can't comment.A good hydrauic rim brake is a good hydraulic disc brake. Theres some pistons and some oil and a conduit joining them. Funny anough one of the best brakes is also the oneof the cheapest Link to comment Share on other sites More sharing options...

MintSauce Posted November 20, 2006 Share I think Avid's are tops....once again it's probably a matter of opinion. I do ride them so it's the only brake I've spent quality time on as well. Here are some facts, some other people's opinions) etc. As for weight , the new Juicy Ultimates are 347grams per wheel, which if i remember correctly is roughly the same or lighter than Marta's, which are supposedly the lightest. Some rich lucky bliksem on MTBR with a Titus HCR ti hardtail(his commuter bike), a Exogrid MotoLite and a titanium Racer X has just built up a new xc hardtail, a Titus Eleven Titanium. He's always run Marta's and decided to try the Ultimates. He says the power and modulation are better than his Martas. And as far as i can remember the general consensus among the press has always been that Avid offer the best performance. The only complaint has always been weight, but that is no longer an issue. I've seen very little negative feedback, from what i can remember, re Hopes, and before i bought my brakes i did quite a bit of research on MTBR. Have a look at the reviews on MTBR.....i don't buy anything before i go there. If anyhing bothers you....ask questions. Remember to take a lot of the negative comments with a pinch of salt.....when people are disappointed with a product they sometimes get over-zealous in their rating of a product. Like i said before, my Avids have been faultless and are simply phenomonal! GoLefty, i understand what you're saying about performance being limited by tire performance. However, a brake with more power means less pressure at the lever to brake as hard, less finger/hand fatigue and better control. With discs i ride with one finger and that one finger uses less force than when it was helped by another finger tugging on a v-brake. Link to comment Share on other sites More sharing options...

Racer X Posted November 20, 2006 Share I run both V and discs, Avid ultimate V's (and levers) on my Extralite hardtail and the new Avid Juicy Ultimate discs on my Specialized Epic. Personally i prefer the V's I just find that you can get better lever modulation. Of course when you hit the wet... well I use my discs. Link to comment Share on other sites More sharing options...

There is always a trade off. I'd rather have the modulation than the absolute most powerful brake. Control comes from modulating the braking power to your speed and the surface rather than just grab and holdon. Link to comment Share on other sites More sharing options...

Ok, from my perspective, as a road rider. First of all, I've never ridden a moontin bike, and prolly never will, so maybe the dynamics are different, but from waht lefty says, it's not too much different to the euro pro style of having "spongy" brakes. You don't want to brake too hard and lock up. Specially not in a bunch of 100 riders doing 50+ Link to comment Share on other sites More sharing options...
MintSauce Posted November 23, 2006 Share Nah....i don't agree. My discs have better modulation than my V's ever did. Road XT, XTR, Avid SD Ti. Nothing comes close to discs IMO Link to comment Share on other sites More sharing options...
GoLefty!! Posted November 23, 2006 Share Mintsauce is very likely a fellow who likes to lock his brakes hence the obsession with power. as far as modulatin goes, V' brakes are far better in modulation but and not too far away interms of brake torque generated. Sure discs are great but the best disc are far far more expensive than the best V-s Link to comment Share on other sites More sharing options...
AndreZA Posted November 23, 2006 Share Okay, I've read though all the responses, thanks a ton. Now, the next question. How does middle of the range V's compare to middle of the range hydraulic disc ie. single piston? Link to comment Share on other sites More sharing options...
Thug Posted November 23, 2006 Share Are you now asking for another 5 pages of debate What brakes do you have in mind when you say "middle of the range" Juicy 5's ? Single Digit 7's ? XT's ? Link to comment Share on other sites More sharing options...
AndreZA Posted November 23, 2006 Share Juice 3 or Hayes solo - DiscAvid Single digit 5 or LX - V's Link to comment Share on other sites More sharing options...
