OOOOOOOh Gee Are Eee
No disagreement from me.Yeah, but the claim that aluminum cranks NEVER give you problems is just as ridiculous as saying Race Face Next SL is durable. Plenty of people have pulled pedals out of aluminum cranks, bent cranks, had interface problems, etc.
IME, Race Face carbon cranks should not be used as an example of CF cranks. They have been systemically bad, while SRAM has managed to make a durable product IME. I've broken 3 sets of the RF and the SRAM stuff has held up amazing. This appears to be due to SRAM using a metal skeleton inside the crank, rather than pedal/axle inserts bonded blindly into carbon fiber with the RF stuff.
Hollow shimano cranks are generally a good value, but they keep changing their chainring mounting standards basically every year or so. There are other metal cranksets that are a good value. If you learn/research a bit about aluminum alloys, you'll see there is a difference between some of the lower end and higher end aluminum stuff.
I mentioned above I love my SRAM carbon cranks and have never had an issue with them. That's also why I asked the above poster who had carbon cranks fail what brand they were.
