The Ouzo Posted February 23, 2023 Posted February 23, 2023 1 hour ago, ChrisF said: Okay .... when all else fails ..... go read the Parktool Big Blue Book. different torque settings for Alu and Steel. Pretty wide range between 5 to 10 N.m. My 6N.m would thus have been on the low end, rather than over-torqued. Though steel bolts seems to be the safer option for e.bikes .... now just to track it down ... And yes, Parktool do recommend a "thread locker", ie locktight. My uneducated guess is that you had one weak one, when it went the extra force took the others out. ChrisF 1
117 Posted February 23, 2023 Posted February 23, 2023 I call bollocks. Chris didn't tighten them properly. They came lose. Put new ones and go ride that Argus like a winner. Dont over think it chris, you'll be fine by replacing them ChrisF 1

dasilvarsa Posted February 24, 2023 Posted February 24, 2023 It Actually Doesn't Happen A Lot. But When It Does It usually leaves U Stranded. I like using the Chain Ring Bolts that Came with the Bikes on the 2X10 Shimano Systems. The After Market ones Seem to be weak and Flimsy.

He only has aluminium bolts on the shelf. Any idea where I can buy a set (or two) of steel ring bolts ? Ek het stainless steel bolts vir jou en staal. ChrisF 1
Migual Posted February 26, 2023 Posted February 26, 2023 (edited) My experience says that most bike shops will not do as good a job as someone who does their own work and takes the time to understand a bicycle properly. Ever since I had a bike shop swap out a fork that nearly got me crashed due to low rake angle, I never went back to a bike shop for service ever again. I learnt to do all my work myself and have never had a problem with a bike since. Multiple Cervelo and Look builds, wheel builds, hydraulic services, etc. For me I mostly see friends’ bikes coming back with problems from various shops rather than being 100% right first time!

Some shops are definitely better than others. I can do most of the basics, but will take my bike in for things like wheel truing and also for jobs I don't have the tools for, e.g. pressfit bb and wheel bearings. LBKloppers and ChrisF 2

Yeah if you can buy the tools they are worth every penny. You won’t believe how many bike shops don’t even use torque wrenches when working. Absolute amateurs!!!! They think they can “feel” what good enough. And when they crack your R80,000 carbon frame who pays for that; the customer.

Two ring bolts gone .... during the holiday I did a "major service" of the bike, including checking all bolts ..... What have I learnt ? Uhmmm .... will ask Mark what I did to end with this ..... Damage ... . Chain got seriously mangled as it got trapped between the ring and frame .... will replace it. . Ring looks bent .... . My ego ... O-well .... rather now than during the Argus. Lessons learnt .... Bolts were too loose .... (despite using a torque wrench) Pulling away, twice, with the ring loose ended up twisting the spider arms 😵💫🤦♂️ Managed to get a new spider from the Darrvin distributors. Dankie tog ... 😁 New chain and a 40 tooth ring fitted (properly tightened by the LBS) 👍 TheoG, dasilvarsa, Scary Rider and 1 other 4

Fred van Vlaanderen Posted March 13, 2023 Posted March 13, 2023 Is the following KMC link compatible with SRAM GX Eagle 12 speed? I've tried to search and can't seem to find an answer. It does however look different comparing to the SRAM link on my chain. It looks like a road link to me. If it is, I'm assuming it won't work. Any advice welcome, please. https://www.takealot.com/kmc-chain-link-12-speed-gold-2-card/PLID73147265

Any advice welcome, please. https://www.takealot.com/kmc-chain-link-12-speed-gold-2-card/PLID73147265 It should work considering the chain pin width and link length has to be the same seeing they are both specc'd as 12 speed parts and likewise there's no material difference I am aware of between chains branded road or mtb. I've used KMC links on many different chain brands incl Shitmano directional chains. The packaging pic on that Takealot listing does also state "Compatibility : KMC & SRAM 12 speed chains" so I think you'll be good but maybe someone else can chime in to confirm that 100%.
