Its the ES70 is the model # You have to find out what length spindle 113 or 118.
if it's the Octalink (splined) then it will be the ES model designation..if square, it's the UN desig. If you're running it on a FS frame..usually they're 73mm shell size and the spindle lenght usually runs 116mm (HT usually run 113mm for low profile cranks). The spindle length plays a factor on your effective chain line..
you need to know the shell size and the spindle length. the shell size you can usually get with a decent metric ruler, just measure across the BB shell. 68 and 72 mm are the 2 typical choices. The spindle length is usually determined by the size of the seat tube but not always. I'd call Jenson and tell them what you have and see what they say. That way, if it's the wrong one it's partly their fault also and makes returning a wrong part easier.
the 68 x 113 was the correct one and works for both bikes and both cranks.
