i've seen this twice now maybe you remember we were talking about "the movement" from Mutiny and cleaner "no sprocket bolt" look we decided on it was too much of a hassle but now the finer threading I've seen twice that it just comes undone and you drive it into your frame like a knick.
is it possible to have the sprocket bolt like with a locknut going the other way, towards or away from the frame thru the crankarm with a locknut on the frame side so it cannot come undone and harm the frame?
