There is a reason why people use breaker bars and 2ft torque wrenches for this nut.

well i managed to get my front sprocket nut (supposed to be torqued to 136nm) off last night with just my fingers. it could be that it wasnt tightened at all of it could be i have super powers. For the time being im going with the latter
