    8 inch rotors and QR axles = pickles and ice cream, or peanut butter and jelly?

    Ive heard from many many people not to use 8 inch brake rotors with 9mm QR axles.
    YET....... I believe I have seen just as many bikes come stock from the manufacturer equipped with the same combination. (Kona, Marin, Norco etc.)
    What gives???

    Fox Forx says not to use anything bigger than a 185mm rotor with QRs.

    How many people are currently stopping their QR's with 8 inchers? (front or rear)

    STOOPID if you ask me. but I actually go fast. poseurs probably could get away with 8" rotors on a wheel held on by zip ties, though.

    serious answer: I think it's kinda reckless. I am running 185mm on a QR fork and I can feel it when I reef on the brake on steeps. I would not want to try 200mm. and I weigh only 160-165.

    I do. But the brake in question is the Hayes MX-2 mechanical, which, they tell me, does not have enough power to cause a problem. If it was any decent hydro, I would have either gone to a 20mm or stayed at 6". No problems so far, but then again this an urban/jumping bike that doesn't have to undergo a whole lot of braking for extended periods of time, like a downhill bike.

    the problem is if the riding you're doing really uses that much braking power to its fullest, you are probably over-extending little 9mm axle/dropouts anyways. So no using 8" rotors isnt inherantly bad (i did it for awhile even), but you are using a qr fork with a little axle and qr which has its limitations anyways. And chances are if you really need that 8" rotor, you may be exceeding those limitations. Remember that disk brakes want to seperate your wheel from the fork

    Zedro, do you think the bike companies that sell bikes with this combination of brake/axle might have been thinking that the people who would buy and ride these bikes are incapable of exceeding the limitations that would cause a problem??

    ya i roll the 8" on my POS manitou black, its held up although the shock is blown out and i need one. But i dont beleive its because of the 8" rotor. I was warned by the bike shop mechanics not to use the 8" rotor in the front of my HT because the fork wouldnt handle it but i went for it anyways and dont regret it. Gives me the qualiy stopping power i need.

    I just don't understand how bike companies are selling this brake/axle combo when I have heard from many people that it is not a good idea.

    i actually havnt seen any bikes being sold stock with 8" rotors. But what i could suggest is that those 8" in rotors may or may not be coming on like techtro brakes which truthfully dont have the piston power to stop that well. But i can only suggest this because i dont know what bakes these stock bikes are comin with

    I know that most stock bikes in the shops iv seen go cheap on you and give u like the worst disc brakes available

    WOW that goes to show how intelligent you are. Whats it like to ride a blown fork? I bet the bike shop guys get a kick out of you.

    You should have never said anything about my hair, Ilikepinktights. You will always get a hard time from me...

    Especially if you keep posting on MY threads.

    Only forks that I've had a problem running a 8 inch rotor with a QR axle are the Fox Vanilla 125 Rs. Supposedly you can run a 8 inch combo with the fork this year. *shrug* The disc mounts cracked on it when I tried running an 8 inch. I don't have the adaptor to run 8 inch rotors with my Manitou Sherman Firefly yet, but I do plan to. And it's a QR fork as well.

    Alright... Lets look at an affordable hardtail that is specced with 8 inch rotors up front... Haro Escape 8.2, is specced with 8 inch rotor and Hayes HMX discs. Given that they aren't the most powerful brakes, it's still a bike that's specced with 8 inch rotors AND 9 mm QR.

    QR with 8" Saint Discs on my Heckler

    I've had no problems running 8" Saint disc brakes front and rear on my Heckler with a Marzocchi All Mountain 1 fork using standard QR. Marzocchi engineers explicitly rates their AM1 for 8" rotors in their manuals, even though they conservatively only rate it for small drops. They only rate leg diameters 32 mm and larger (like the AM1) for the 8" rotor due to leg twisting issues.

    This issue came up in the Shock(?) forum around October, when I was building up my new ride. I had my LBS check this out thoroughly. They even called up Marzocchi to make sure there wasn't a typo in their manual. I did the same via email. No mistake. Marz rates their QR for 8" rotors. Note the beefy dropout has massive structural support (see below).I can't even turn the skewer handle because of the beefy support forming a recess. Same beefy support with the Heckler rear drop out.

    From more reading and talking with others on MTBR and elsewhere, the issue with the standard QR is leg twist, prevented by the stiffer large leg of the AM1, along with improper skewers such as Ti (that could stretch) or lower quality and improper skewer tightening. The feeling from others was that a good quailty Shimano XT or Salsa skewer tightened properly would not be a problem.

    Note I use 8" Saint rotors more for moderate XC (under 2' drops) than technical DH. My need for 8" is more thermal related than for big forces and stresses. I use big rotors because of fade in long steep 2000' descents at my 330 lbs (me+gear+bike). My 6" Hayes rotors were turning colors and then fading COMPLETELY on long descents. I could slide my bike like no brakes at all with the levers pulled to the bar. They'd recover to "normal" after a few minutes of cooling and pumping. My 8" Saints work super with no fade whatsoever.

    Marzocchi's engineers formally approve 8" rotors on their QR. My LBS and other shops say it's OK. Others on MTBR have not had trouble with proper QR skewers used correctly. My wife says it's OK (as long as I keep the life insurance high ). So I'm using them. No problems so far.

    Man, you sound so stupid it isn't even funny. Just stop talking ok?

    The 04 coiler came with 8" Hayes HFX-9 brakes on a QR drop-off. The 04 enduros came with Shimano M-965 XTR hydraulic 8" discs on a Fox Float RLC TALAS.

    Whereas say a 2003 Formula disc hub with standard qr axles also Does Not recommend using 8inch rotors because it would propbably break the skewer or damage the hub.

    What I'm trying to get at is......
    If there were any question about mechanical failure in the first place , why would ANY bike companies sell bikes with 8 inch rotor hydraulic disc brakes and 9mm quick release axles, front or rear??????

    i had an 03 DJ 3 and when ridin on a DH trail i had to brake very suddenly and my front wheel shifted from the force... i really dont recomend running 8 inchers becuase that is too much power for the axle to handle.

    i wouldnt recommend ridin qr period unless it was on an XC bike...

    Uh, no it didn't. It came with a 6" rotor, or at least mine did. I have a 8" rotor on right now with the stock brakes and forks and haven't noticed any problems but then again the front end is so flexy on rough stuff I'm not sure if I would notice anything.

    If you gotta use QR AND 8in, you better go with a solid non-QR axle.

    I've seen QR bolts snap before, it's NOT a pretty sight, esp. if it snaps right before a jump. A buddy of mine face planted HARD when his wheel fell out of the fork in mid air.

    Having a wheel fall out of the fork is bad on disc brakes, but not quite as bad on V-brakes, due to the Vbrake preventing the wheel from coming out of the dropouts.

    For heavy/hard riding, 20mm up front is required IMO, also adds confidence. On the other hand, QR rear hubs are just fine for any bike, never seen one of those snap. Even if the rear wheel fell out, it wouldn't be a super spectacular crash like losing a front wheel. I had the whole rear end of one of my old bikes completely sheer off the bike at full speed. All it did was cause my crank to tear into the ground and I came to a stop still standing up on the bike. Sucked ass carrying my bike for 4 miles though!!!

    it realy is worth payin extra and getting a 20mm axle set up and wiht the introduction of the maxle system its not exactly rocket science to get the wheel off if need be

    Oh ya, you're are right. I think my friend had his switched to a 8" before he bought it thats why I thought that.

    ur a cock, the frok wasnt blown due to the 8". The fork was an '02 BLACK that came stock so i rode the **** out of it. And it sucks riding a blown fork but i dont have the money right now to afford a new one, ill be getting one in a few weeks hopefully. Not all of our mommy's buy our sh!t.

    No kidding! Was it the DOT fork?

    I like Marzocchi, but some of thier OEM stuff is just down right JUNK and dangerous!!! The MZ comp fork is a perfect example! I've seen "freeride" bikes stocked with it.

    I give Manitou props for at least making better OEM stuff. A lot of cheap low end FR bikes at least come with the 20mm shermans, which I would take over a crappy Zoke any day.

    I never said that your brake broke your stupid fork. I dont care anyway, its the fact that you're stupid enough to ride a blown fork.

    im stupid enough to ride a blown fork? what the fuq am i gonna do instead, i cant just whip out a new fork and install it right of the bat, i have to ride what i have for now untill i can save up enough money. I would get a job but i dont have a car and without a car i cant get to the job, so I'm in what is known as a catch-22.

    They put 8in rotors on those bikes because they look cool and the kids will ask mom to buy them.

    If your riding agressive enough that you NEED and 8in rotor then you should already have a 20mm thru axel fork anyways. Just my two cents on this whole thread, which i must say is probably the ghayest thing i've read in quite a while. Later kids.

    How many people are currently stopping their QR's with 8 inchers? (front or rear)

    What if I were to say that I've had a wheel pull out from the dropout of my fork with a 6" rotor?

    Even worse yet, what if I told everyone that it was with a mechanical disc brake?

    If you do a bit of research you'll find out the truth. From your original post you're already half way there. It might involve some long distance phone calls depending on where you live though.

    Sell your bike and buy some rollerblades or something...

    People should DESERVE to ride, and you shouldn't be one of them.
    Sorry, but that's my honest opinion.


    Nice excuses for not having a job... I dont have a car either..
    And if my fork were blown I would simply NOT RIDE MY BIKE!!

    Go sell lemonade or something. There are no excuses for not making money. You are proving to us all that you are a wothless, resource-devouring-leech-of-a-human-being, taking up precious space, air and water, and completely wasting my time.

    It almost looks like there is an equal amount of people who have and havent had problems so far.

    So if 8 in rotors are known to break little qr's, WHY THE HELL are bikes coming stock like that!!

    Are the bike co's just like fugit or whut?

    well maybe ur the one who should invest in a nice pair of rollerblades if u dont want to ride a bike if the fork is out. I mean ya i will get a new fork in a bit but i dont want to just have my bike sit there in my garage. Granted my frok is down to about 2" of travel, ill still ride it even though its shitty. Im not just gonna let my bike collect dust in my garage like u might. U really need to reconsider which one of us should be getting those rollerblades

    If your riding agressive enough that you NEED and 8in rotor then you should already have a 20mm thru axel fork anyways. Just my two cents on this whole thread, which i must say is probably the ghayest thing i've read in quite a while. Later kids.

    HAHAHAHAHAHHAHAHA you make me laugh..
    If my fork was blown..
    My bike would sit for a day or too, then..
    I would buy a new fork, because I have a job, and therefore, I deserve to ride...


    Now what size rollerblades do you want me to buy you?

    ...SInce I own you.....

    ur an awefully smart man...so basically those of us who cant afford to get a new fork right away just shouldnt ride bikes?

    just reread what u write before u send it, maybe then ull realize what ur writing. On a second note, dont bother cause this argument is going nowhere fast so im just gonna call it a day and we can part ways.

    Pretty cool of you to actually make a comment on my signature. I take it your the tough guy member of the wannabe zachdank norcal crew right? Alot of people with an education know where maine is. Alot of people who know where some of the best riding on the east coast know where maine is too. Maine is the highest state in new england. Yes new england is in the US, its not to be mistake with england, which is an island in europe. Its all tech riding (yup, there are roots and rocks) that from judging by your pictures, would straight up hand you your ass in more than 10 ways. I've said it before and i'll say it again, i dont like you, your a f*cking toolbox. This sites gone to the sh*tter over the past year. Its no wonder i dont post here much.

    I'd do (i've done) 8" front rotors with a BMX axle (and axle nuts) in a front hub. Shimano hubs can be converted in this manner.
    I know in my heart that Ellsworth bikes are more durable by as much as double. AND they are all lighter...Tony Ellsworth

    Yo Jsun, you probably know this, but if you are using it as a urban/dj bike, I wouldn't recommend using 8" rotors in the first place... For dj'ing you just don't need em, and for urban they get in the way if you are planning or grinding on the left-side of your bike. Good luck man.

    8" on a Minute 3, plenty of power to stop a Giant VT with a 200lbs rider using standard QR hubs.

    I dont know why everyone thinks that I would want to put this combo on MY bike!!!!!!!!!!!!!


    I never said that!!!



    I just want to know why bike companies dont care about the safety of people who just might push those brakes and axles to the limit. If they did, they wouldnt sell them like that.



    For the record:
    I dont want to put 8 inch rotors on my bike!!!

    The fact that there is a "question" about something is really irrelevant. If engineers and or designers were concerned about "questions" then space travel, many of our new materials, and techniques for extracting natural resources would never exist. From a liability standpoint, if a mfg. says "no 8" rotors on my fork", then the idiot who put an 8-incher on and took a dirt nap is at fault. (unless the action was foreseeable use, blah blah blah...)

    Engineers and designers use data, calculations, and professional judgment when evaluating decisions.

    That being said, these brake / rotor combinations must have been checked by someone. Does that mean some crummy state-schooled fraternity brother moron engineer made a mistake? Maybe. More likely, the application was evaluated, and a decision made based on facts.

    Take Big Larry's advice - call the manufacturer before installing an 8-incher on a standard QR fork that was not OEM equipment. It can't hurt.

    simple answer:

    the world is full of PinkBike poseurs. it's more important to have a bike that looks sickter gnarcore than it is to be able to ride that bike to its limits.

    the times I notice my 7" (185mm) rotors stressing a 9mm QR axle junction are when I am riding stuff that most folks walk. steep and full of stoppers. the number of people who buy MTBs that actually ride such stuff is maybe 3%. you think that's true danger? I say the danger is in the rider's choice of terrain to ride, or tricks/stunts to try. it's not the bike, at least not in the types of bikes that would come spec'd with 8" hydro disc and 9mm QR axle.

    NOBODY is promoting danger. the choice remains up to the consumer. what, are you trolling for litigious plaintiff's personal injury lawyer arsewhypes, JSUN?
