his latest video shows flawed design of sram's gxp system (which is now dropped). i remember when i first got gxp crankset and figured out how it works i had an "eh?!.." moment. i still have two of them (one came with a bike and still works ok, another is a quarq dzero power meter - also works ok), but both use threaded type bsa bottom brackets, so at least they don't creak. the third gxp crank i had died in a peculiar way - the spindle separated from the spider..
i've come across some shoddy design and "engineering" from other manufacturers too, it appears that cycling industry is lagging 20-30 years behind motoring in terms of innovation and quality. we are only cyclists, serves us right.
