hello! im the guy thats changing the BB of a 98 trek 6000 mtb.
one quick question.
pic related is the BB i removed. im not totally sure if it was the correct BB for my bike.
so i measured the bike's frame BB cage /shell (dont know its correct name), and it is 73mm. width.
so i guess i need a 73mm width BB right?
and heres the real question, pic related bottom braket says "68 x 122.5" (green arrow). but on the code name it says "73" (red arrow). with the cups on it measures 73mm (can be seen in pic, camera nagle makes it look a little different though but it is 73mm)
. so is this a 73 or 68mm BB?
i should go get another one that is the same right?just ask 73x122.5 right?
this discrepance in whats pointed in the green arrow is confusing me, thanks!
