Yes have one as spare. Point is one isnt suppose to ride with a spare chain in your back pocket. Riding with GX is like owning a landrover. Its amazing until its not

Not on this bike but I have many other chains in the household. Will try XX1 now

If it is fake then the SRAM distributor in SA gave me the wrong product which I doubt.

I’m reading more and more about the same issue happening with SRAM GX chains elsewhere. Also, first example of a guy who snapped his chain on 2 places simultaneously. something is seriously wrong with this product…

I wish it was due to excessive power, but alas. FTP a tad over 300. I’m just an average rider. The chain issue cannot be a power thing

Its a sram eagle chain. Got it from Sram. Some links says sram others say eagle

Not worn by much - 0.39% (havent been riding much over the last couple of years on this specific bike). So technically it should still have some life left.

Who is Matt and how do I join him? 😀

Except the current casette effectively has only had one chain. The new chain bought in Jan is its second- shouldn’t be worn that quick but I guess it is possible. Normally a casette lasts 3-4 chains depending on use.

I am super happy that the rainy season is now over, as I will most certainly be struck by lightning if I were to leave the house..... TWICE. So, update after a couple of years of riding my "replaced under warranty GX chain and GX cassette".... it happened again! Out on a ride, having fun and then snap - chain gone. In fact, the weirdest thing happened: the chain did not just snap, a piece with about 10 links broke off and was lying in the dirt road. ie. two links broke at the same time. Kid you not! So I used my spare link and that of a fellow rider to get me going again. 5kms in, it snapped again. This is when I threw in the towel, the group rode on and I had a boer-maak-a-plan to get home. This time I had around 8 links look like the image below. I bought a new GX chain on my way home This was January 2025. Two months in I noticed that eary tiking sound when I put power down. Took my bike for a checkup before the Sani2C couple of weeks ago thinking by BB was acting up and the mechanic told me my chain is worn and should be replaced. TWO MONTHS OF RIDING?? Hauw... Anyways, seems after all this I'm back to square one. I don't think I have energy for another root canal to try and get to the bottom of this one... If anyone has the contact details of someone at SRAM - please PM me.

great coffee and convenience doesn't normally go hand in hand. However, the Jura machines are probably the closest you'll get to great coffee in a bean-to-cup setup. It is consistent and these machines lasts. So if convenience and consistency is your thing, you cannot go wrong with a Jura. Dont expect the same quality tho as you'll get form a cafe quality manual or semi-auto machine. different league all together.

Am looking for a 203mm post mount front adapter. Shops dont seem to keep stock in the 203’s.

I wonder how many other of these types of issues (‘hidden defects’- not cassette specific) exists across the various brands and models that the general public just doesnt know about. Kind of makes me feel like a mushroom. Anyways, on a positive note, I received my long awaited 4 pot Zee brakes and upgraded rotors yesterday and the new cassette and chain tomorrow. If all goes well I’ll be hitting the trails on Saturday! Cant wait.

lol you are right.

I hear you. Rationally speaking you are probably right. Right now though I am wondering what I would get for the complete SRAM GX groupset incl brakes, cranks, drive train, Syncros 3.0 29" wheels the works. The chain and cassette is brand new

You should have said this 7 pages ago - that would have saved me hours of investigation... :-) On the chain stretch wear thing - that's a separate debate it seems and I am with you on this one, if its stretched/worn/elongated etc, it means its useful life is running out like with all mechanical things and soon to be replaced.

This is an update on the outcome of my Snap-Crackle-and-Pop ordeal. It appears that the problem lies with the GX cassette and NOT the chain. The cassette has a manufacturers defect - certainly the model I had (2018 stock). When the chain is running on the 18 tooth cog, there are two adjacent teeth on the 16t cog that interferes with the chain plates running over the 18t ever so slightly. The interference is caused by the shape of these two teeth and its (mis)alignment with regards to the others, placing it slightly closer to the adjacent cog on a cassette that already has very tight tolerances. This puts a force perpendicular to the chain while under normal pedaling tension which explains the occasional clicking sound at is catches the chain plates. (see my attempt at a picture to explain this) Over time this causes the chain plates to fail under this undue stress resulting in snap, crackle and pop's. The above is of course my synopsis of the problem - having read up a lot about alignment issues on the GX on other forums, checking out videos of the two mis-aligned teeth and noticing way excessive wear on the said two teeth on my own cassette. This, plus 1. the agents requesting the chain AND the cassette for inspection (which was a bit puzzling at first), 2. the agents' original response which downplayed the issue from the get go and suggested wear and tear as the cause and 3. upon enquiring about the outcome of their assessment, I was informed by the workshop manager that SRAM was 'not happy with the middle part of the cassette'. Outcome - full replacement under warrantee. expecting the new bits to arrive tomorrow. Not quite sure what to make of this whole thing. I still think SRAM is a great product but it does feel that this defect is being hidden from the general public, hoping people wont notice. Had I simply replaced my chain with an XX1 without getting to the bottom of it, I would have wasted that money too. If you are now worried about your own setup and that your warrantee might have expired - some people (I do not recommend this btw) have successfully modified their cassette's by filing the two teeth back ever so slightly (using dremmel or the like) to avoid interference with the chain running on the 18t. proceed with caution please when considering this as its an expensive piece of metal to test your diy skills. Good luck

I bought a Thule rack from Volvo in Bryanston few years ago. was the cheapest around at the time. If Barry doesnt sort you out, give Volvo a call.

I was thinking of this. Although I havent had this bike clamped on a carrier for the last probably 5 years or so. The ‘Crack’ only started appearing in the last couple of months. I could not spot any visible scratches or other deformites on the tube which is what puzzles me. Would alu not bend instead of crack as Eugene suggests?

I agree its a strange place. This particular bike doesnt go on bike racks. Workshop clamp possibly, however the guys who services the bike uses the partktool clamps, so doubt it.

I noticed this crack on the top tube of my CAAD5 frame. Its about 10mm long and feels smooth to the touch. Is it common for paint to crack in this way or could it be the frame? Its located around 120mm from the headset on top.

It is old enough to be considered a classic I think - if this is anything to go by (Same era Cannondale): https://www.globalcyclingnetwork.com/video/retro-vs-modern-cannondale-pro-bikes-cipollinis-caad3-vs-uran-s-supersix-evo

I see you mention Jhb/Pta - For my snap crackle pop problem (Chain) I found Cajees Centurion carried some stock- have you tried them?
