Made out of an Aluminium cheese, softer then Hollands best Gouda

The whole thread idea was to replace with a steel bolts to do away with the aluminium 

that is steel I think even though the description say alloy … I think that refers to the cap

Have you ordered one? Only thing that looks steel to me is the washer. Everywhere on the ad states Black Anodized Aluminum

well you could have walked into MacD and got ripped R200 for Vegan cheese burger deluxe meal.

Its all kind relative. R200 could kill you on the onehand while R450 for a genuine part brings peace of mind.

YEah older Shimano cranks were bulletproof. The M960 XTR I bought in 2002 is still going strong but I've run out of spare chainrings and Wolftooth is out of stock to convert it to a 1x system (uses a stupid 102mm BCD fr the middle and outer-rings- Csixx don't make these either and it will likely be expensive)

The 54N.m torque required to hold the crank is just silly. Cannondale Hollowgram's interface is free to use but that would be a slap in the face for the likes of Shimano and SRAM so everyone has a stupid work around. The Hollowgram/SRAM/PRaxis Works/ Race Face style crank interfaces are just adaptations of the square taper and Octolink BB crank interfaces. They work, but ya well everyone wants to be different so we're stuck with endless standards thanks to trivial patents

SRAM pricing is higher yes. Look at the number of MTB teams they sponsor. They have been the technology leader in cycling components since the mid 2000's in both road and especially MTB and now Gravel. That alone justifies their higher price positioning. 

Higher prices t bricks and motor vs online imports is not unique to SRAM. It's the same for Campagnolo, Shimano and almost every other bicycle component brand. If you want good value and global pricing then Wheeltop, Ltwoo and other Chinese brands is were the value is at.

Why Lyne’s last AMP crankset was such a unicorn. Looked like Hope’s, had Shimano spindle/mounting interface, sram dm chainring interface. Best of all worlds. And also came in 165mm. Ive tried asking why they stopped making them…but im convinced the answer is legal 😅

we need @cSixx to start making us blingy cnc cranks👀  save us from the corporate juggernaught!

they stopped making them because they ended up making no money off the darn things due to p*ss poor tolerances and warranty after warranty after warranty

I have a  Race Face crank on one of my bikes - I quite like their system. No silly hidden extractor bolt, you just need a crank removal tool and a BB tool to fit a chainring.. Actually that's way too many tools 🙂
