S/POSTS CRANKS BRAKES SHIFTERS BITS AND PIECES

how does this hollowtech business work? you say hollowtech cranks with an isis fitting? i thought hollow tech was a thing of its own :?
 
Dont really know better ask shimano,no, to be fair the cranks are marked up hollowtech which i believe is a hollow crank arm. the bb fitment is isis type which appears to be a splined fitment similar in idea to the old square taper fit.Im sure any intelligent cycle mechanic will rip this article to bits!!!

It will be for a Shimano Hollowtech BB which is splined but different to Isis, Hollowtech II is the new version with the BB spindle attached to the driveside crank
