im sure this has been covered many many...many times before. BUT I CAN'T FIND IT. so im sorry in advance...is the difference in the 89mm crank vs 87mm crank, are the benefits greater than the downfalls of both these cranks. from what i understand, 89 will eat away more at your engine in abuse. i already have an 89mm. im really thinking about getting rid of it and going with an 87mm crank. i jus don't want the worst for my build. can anyone, maybe give their opinion. maybe i can build from there. thanx

 

what is the reason ur wantin to do this?

 

i need to know what my best choice is gonna be is the 87 mm crank better tha the 89 mm crank. they are both at an arms reach for me.i'm gonna make more power with the 89mm, but is the stretch worth the sacrifice of poor rod stroke ratio. i jus want some honest opinions. if you were in my shoes...
