    XX Cassette...36t Ring

    Does anybody know the part number of just the 36t ring? I would like to order one for my cassette, but the local bike store can't seem to find this part.

    Can you clarify why you need the part? We don't actually offer this part alone in the aftermarket. Thanks. I assume you are talking about the large cog for an 11-36 cassette.

    My understanding is that the XX 36T cog isn't typically available at bike shops in the US anymore. I tried everywhere and finally had to buy it on Ebay from a bike shop in the UK (Pro4sport).

    bama,
    Why aren't these readily available in the US?

    DavidR1,
    Any luck finding one?

    I'd like to know as well. When the XX group was launched Sram heavily promoted the fact that the aluminum gear was replaceable. Now that people have worn them out they can't get them.

    I know it doesn't help you guys that need the part now but there is somebody in europe that should be producing these in ti shortly and his price will likely be close to what the sram one goes for.

    We had them available briefly, but it caused a lot of people to try taking the cassette apart just for the fun of it and not putting it back together again properly. If it's not done accurately it will cause a potential bad shift and damage to the parts.
    We have not found that the large cog wears faster than any of the other cogs, even under heavy use. If your large cog is worn, it's likely the other cogs are also worn.

    If somebody makes one from Ti at a reasonable price, i have a job for him or her. It's very unlikely to be lighter and fulfill our testing.

    If you get one, and insist on trying to replace it, do it carefully. It must be clocked properly so that the pins match the holes on the cog, and the cog must get pressed on dead straight, and all at one time. otherwise you can damage the pins or cogs and the large cog can eventually work it's way loose. Same goes for removing it.

    Jeez man - you guys have videos on the net of how to take apart your forks and you're saying that we can't have a simple gear for a cassette ? Just put a video online of the correct way to do it.

    So when I need the cog, and call sram to complain that I can't get one, is the offical script going to be that I need to replace the whole cassette, because you assume that its all worn the same ? There's going to be a lot off pissed off riders if thats the case.

    I agree with you completely, especially the comparison between the cog replacement and the daunting task of rebuilding a suspension fork. The first bike I ever built is a full SRAM 2x10 29er and it was easy with the right tools and SRAM’s excellent installation instructions. Later, my aluminum 36T cog happened to wear out before the steel cogs. I bought a replacement 36T XX cassette cog, replaced it myself and thought it was a pretty easy task.

    Chris, SRAM has some of the best installation instructions I’ve ever seen. I’m confident your team could provide the replacement part along with first-rate installation instructions.

    True. They give do it yourselfers more info than any other company. As an experienced wrench I really appreciate that. Which is why this story seems so out of character that it has me questioning the source a little.

    Still no replacement rings available from US distributors. I run my bike 1x10 so I use the 36 a lot. I'll probably need a new one next summer and if I can't get it I'm going to be pissed.

    Has anyone made a aftermarket 36T cog in a different material than alu? I spend a lot of time on the largest cog, so the alu is worn out after only half a season....I'm in the market for a replacement. Love the steel part of the cassette, hate the alu-crap.

    Mattias Hellore said months ago that we was waiting to receive a 36t cog from someone so he could make one in ti. Don't know if that ever happened. I think he got banned for talking about his products in the weight weenie forum.

    I'm not persuing it now, but if someone else wants to contact him you can google - experimental prototype bike - and find his site.

    Geez guys, just go buy an XT or XTR especially if you're not all that worried about a tiny bit of extra weight.

    To already own one means you've considered the pro's and con's before parting with the cash and found it worthwhile. So the girls and guys who already own an XX cassette would be very interested in a 36T cog replacement, even if they also run other cassettes.

    Do you realize that sram sold thousands of these before shimano had 10 speed cassettes on the market? And that sram publicized that the big cog would be easily available and replaceable?

    I too have run into this issue, just replaced my chain and only the 36t was skipping. LBS says they've discontinued them. WTF SRAM??? Do you think I'm going to buy another one of these - NOT!

    I've voted with my feet, and now am running an XTR, which goes on in pieces that are replaceable.

    I have ordered a titanium 36t XX-cog from Hellöre. 8 weeks delivery, 100 euro inclusive shipping. Will post pics when I get it in April. Around 50g.

    Experimental Prototype

    I am really curious to see bama coming up with a good reply to why a replacement part not being available. It is really hard to see why SRAM is choosing to screw it's customers over by not supporting their product.

    Yep, exactly why Ive invested in them as well... Seriously what is SRAM thinking right now??

    First they don't make Black forks anymore and now this Just this year SRAM has lost all my Fork business and now all my Cassette business. Keep it up SRAM and you wont have any business left

    I hear ya bro. I dumped my XX brakes in favor of Magura MT-8's and I'm not looking back. No more turkey gobble, rubbing brake pads, constant bleeding. What kills me is that every time my LBS called SRAM about turkey gobble (on multiple SRAM models on multiple bikes), they always acted like they had never heard the phrase turkey gobble before. Granted, they would always be happy to send another set of pads or rotors, but they were playing dumb to the whole problem.

    MT-8 brakes

    "Just ordered the mt-8s. Are they as good as they appear to be?"

    Just as light as the Sram XX, BUT w/ more braking power, very quiet, AND I don't have to freaking bleed the brakes every couple of months.

    MT-8s are my brakes from now on.

    My XO 11-36 was skipping, looked down and saw this:
    XX Cassette...36t Ring-imageuploadedbytapatalk1343457366.574373.jpg

    Anyone seen this happen? I mean, why should that be the cog to fail?

    Disregard. I thought you were talking about the wear on the aluminum cog. Just noticed the the missing part of the other cog. Rock or something caught in there, or it was just a defective cog. Time for a titanium XTR cassette.

    Need an aluminum 36T, SRAM!!!

    OK, I now own TWO PG-1099 cassettes in 36T.

    Yesterday, during my ride, I lost the ability to stay in my next to lowest cog... On examination, I found it was due to a broken tooth on the 36T...

    Look, I know the 36T is aluminum, but you SAID there'd be replacements... I have the tools and the knowlege and experience... I just need the dang part.

    Here's what happened to mine... (BTW, less than 125 mile son this cassette, and this is an XC bike... not even riding anything super tough/rough.



    In profile:



    What's the word on that titanium part? The old XTR had titanium cogs on the top two gears... never had a problem.

    That looks like a rock hit it. But I'd still call sram to complain that the whole cassette is now useless because the part they said would be replaceable isn't available.

    Oops! Sorry guys I just realized that they only offer individual cogs up to a nine speed cassette. But they do offer a 39 tooth titanium! Pretty cool... With that in mind I'm gonna leave my previous post up.

    Actiontec now has a 36t option under "Single Titanium Cogs"... has anyone tried it?


    I'm pretty F'ing disappointed with SRAM... I've been wrenching on bikes for 20+ years now and they tell me that they won't sell me a common replacement part to fix something that doesn't work because they are afraid that I "might" do it wrong?

    Seriously guys, disposable $350 cassettes?

    I just pulled my cassette, carefully removed the 36T cog with a taped flatblade screwdriver, a little bit at a time while rotating around the perimeter, cleaned everything up very nicely with the inside of the cassette wide open, replaced the cog, carefully pressing it back on with my thumb at each pin point, and then seating it with small channel locks with taped jaws, again a little bit at a time while rotating. Alignment is easy, as the one flat/short pin on the main body lines up with the single blind hole on the 36T cog. Piece of cake. My only concern would be that it loosens up if you do it to the same cog often , i.e. to clean the inside of the cassette. There are many normal maintenance tasks that are more difficult than this.

    XX Cassette...36t Ring

    Posted in the wrong thread: here it goes again.

    Got my XX 36t titanium replacement cog from hellore.se this week. The XX cassette retails for an unbelievable USD670 over here, so the USD130 paid incl shipping was ok to save a half season use cassette from being disposable.



    The cog has an aluminium spider for more contact area against the boss. The cog weighs 87g, 31g more than the original alu cog 56g. Not bad. The finish is good.

    XX Cassette...36t Ring

    That looks awesome. Is this something he makes or a one off? I've seen regular 36t rings on his site but not one to match up to the xx cassette.

    Just put a 3rd new chain on my 15 month old XX drivetrain and now my chain always skips on the 36tooth cog. Was thinking the derailer might be the cause since it was not as strong anymore and the small philips screw that holds the cage post has developed a half moon flat spot. Now after reading here it makes more sense that Ive just worn the 36t cog(should have replaced chain sooner).

    Even though to my eye it seems not that bad , is it most likely to cause chain skipping under power?

    Every other cog works fine it seems stupid to give sram another $400 for one cog. Can a new cog really be put on without special tools?

    I just had to replace my XX cog stack due to worn chain too. These thinner 10 speed chains don't last like they used to folks. My lbs has been watching this issue over the past two years and has figured out that if you ride alot you need to replace your 10 speed chain AT LEAST twice per season to get maximum cog stack longevity. XX stack = way cool, light, RACING equipment. Not built for the long haul IMHO. Factory racers get this stuff for free and replaced often. I am now riding an XT stack and bought a dropper post with the savings... If we could just replace the individual cogs on the XX stack...
