sounds about right...really god bik for the money, i loved mine when i had it....they ride pretty well and are supposed to be amazing for taps. the zoo is shorter (1065 against 1080 ) and ever so slightly higher bb ( 15 against 10 )
tape a piece of wood to the back of the cranka rm...flip the bike over then tap the crank so it hold's itself up.....pour boiling water over the isis interface and crank arm...proceed to twat with a hammer ( closest to the axle possible to help prevent crank bending. )
